While most plumbing jobs require a licensed professional, there are ways savvy homeowners can save time and money by safeguarding, upgrading or repairing their own systems.

Theres quite a bit homeowners can do themselves, especially when it comes to maintenance, says Gale Bellows, a journeyman plumber and service manager with South West Plumbing. If you have basic tools and some inexpensive supplies, here are six things you can do to prevent costly plumbing disasters and increase the life of your existing pipes, valves and appliances.

Protect your exterior faucets from freezing and breakage. Install inexpensive padded or foam faucet covers (about $10 each). Properly sealed, these will prevent or delay pipe freezing. While youre at it, drain the garden hoses youve disconnected to protect them as well.

Remove and clean (or replace) sink faucet aerators to improve water flow. The tips of most faucets can easily be unscrewed and the mesh aerator screens rinsed to remove grit. If a screen looks torn or damaged, take the aerator to the hardware store to buy a matching replacement.

Replace a worn toilet seat. This is a cosmetic repair, but many homeowners want to upgrade seats to more attractive or durable models. Soft close seats, which close slowly rather than dropping down with a crash, are popular, Bellows says.

Remove and clean the P trap under your sink. P traps (which are actually U-shaped) are critical parts of your plumbing system. Water is supposed to stay in them, forming an important barrier that prevents gas from your sewer from coming up into your house. Problems occur when a P trap gets clogged with hair or soap and the sink starts to drain slowly. Rather than using harsh chemicals, you can remove and clean the trap in a few minutes. Put a bucket under the sink to catch water and gunk while you work. Then twist off the slip nuts that hold the P trap in place. Once youve cleaned the trap, reattach it and twist the slip nuts. No need to use plumbers tape or worry that it will leak, according to Bellows. When you tighten the nut, it seals automatically, he says.

Check your water pressure. While many of us complain about low water pressure, the real enemy, Bellows says, is pressure higher than 80 psi (pound-force per square inch). Excessive water pressure can damage valves on water heaters, dishwashers, washing machines and other appliances. You risk flooding your house if a stressed hose or valve ruptures. Fortunately checking water pressure is cheap and easy with a psi gauge ($5 to $10 at the hardware store). Attach it to an outside faucet, turn the faucet on all the way, to measure system pressure. (Bellows suggests measuring psi at night, when few people are taking a shower or running washers.) If water pressure exceeds 80 psi, its important to call in a professional plumber address the issue.

Know the location of all the water shut-off valves in your house. That way, if a leak occurs, you can quickly turn off the flow to the sink, toilet, water heater or washer. If you are uncertain about where a leak is coming from, use the main water shut off to control damage.

Do-it-yourself repairs can be quick and inexpensive, but Bellows cautions against tackling more complex plumbing repairs or installations on your own. One problem, he says, is that the system you are repairing, or adding to, may not have been built correctly in the first place. Often, especially in older houses, the plumbing is out of code or lacking in required safety features. A professional plumber can spot these existing problems and avoid adding to them.

When to call in the pros? If you notice dampness on ceilings, walls or floors near pipes, bring in a plumber to analyze the situation. The leak may be minor, but ignoring it can allow mold to grow in walls and flooring, creating a larger problem.

Remodeling a kitchen, laundry, or bath? Youll want to get a plumber involved to make sure your system can support the new fixtures it may need updates. Bellows advises scheduling plumbing work early in your project, right after rough carpentry and before any electrical, flooring or tilework gets underway.

There are certain plumbing problems that require immediate attention from the pros. These include a malfunctioning water heater or the smell of sewer gas in your home. You dont want to risk a flood or an explosion, Bellows says.

Which are the best places to install a tankless water heater?

Manufacturers and users agree on one thing. The location of the tankless water heater affects its efficiency. Ideal locations ensure that water remains hot even during the coldest season. There is a direct correlation between the heaters performance and where it is. For example, installing it closer to the demand source ensures that less water goes to waste.

There are various options when it comes to where you will position the heater. Take time and assess the different places you can place it, as it means a lot to its performance.

The tankless water heater is small in size. Thus it can be put in small spaces such as under-stair storage areas, closets, in pantries or under the sink. Be careful to ensure that your water heater is convenient and safe in case future servicing.

A tankless water heater is for indoor installation only. In case you install it outside, get a suitable enclosure. This is to protect it from splashed water, rain, insects, direct sunlight and debris. Avoid installing it in locations that may subject it to freezing.

Frozen water inside your tankless water heater may cause severe and permanent damage. And most of the time it isnt covered by the warranty. For a frozen water heater system, wait until it has thawed before turning it on and inspect leaks in the system. If you water has frozen inside your water heater contact the manufacturer.

Choosing the best place for your water heater is quite tricky. Luckily, there are several options. Lack of proper planning may lead to irregular water temperatures. Poor flow of water, need for regular maintenance, or worse still, damage to the whole system.

Its better to install the tankless water heater in the same location where the old heater was. Only a few changes are necessary. This way you will cut the installation costs. You will use the hot water line, and water and gas supplies that are already in place. Change the venting to accommodate the new tankless water heater if youre to follow this idea.

Otherwise, consider the existing plumbing configuration. Your desired location should not demand significant alteration to the existing plumbing work. This is because relaying the entire system afresh may lead to unnecessary costs.

The site should be close to the main electrical panel. Keep it close to all the areas that need hot water including bathrooms, kitchen, and laundry area. When its near the points of use, the time taken by the hot water to travel from the heater to the fixture will reduce.

A dedicated gas line is also required. When the furnace and water heater are in the same room, you only need one gas line to supply the duo. But, this can create an issue whenever the 2 are operating. Even worse, the 2 units may not get enough gas if the supply line isnt large enough. In most cases, the water heater always gives way to the furnace thereby depriving you of hot water supply. This can be a huge inconvenience.

To reduce these occurrences, consider following the manufacturers installation manual. You may also involve an experienced plumber if plumbing isnt your thing. It pays in the long run. Always ensure that that the heater is accessible for maintenance.

Youll enjoy greater flexibility during installation if your home is custom built. But slight renovations will also fit the bill if you bought your house.

As mentioned earlier, having the water heater placed where hot water is much needed is vital. For instance, for a home with two stories and a basement, the worst place to install the heater is in the basement. The best place to install the unit is on the second floor. This is assuming that your laundry room is in the basement or first floor.

Ensure that the heater or outlet water pipe doesnt touch the combustible materials. Keep a distance of 24 between the combustibles, the water heater, and the output hot water pipe.

Again, remember to be a law-abiding citizen. Install your tankless water heater according to your State or Citys local codes. If theyre none, at least follow the recent edition of the National Fuel Gas Code.

For safety reasons, the water heater should not be on air conditioning lines or under pipes that can drip. Also, dont put the water heater above an electrical box. This could cause a fire in case of water leakage.

Tankless water heater requires a higher voltage power supply. As such, ensure you have large diameter gas supply lines.

Do not adjust manifold gas pressure as its computer controlled and is preset at the factory.

Ensure that children cant reach the electrical sub-panel, outlet water pipes. This will prevent them from injuries or tampering with temperature controls. The outlet water pipe can get boiling at times, which may pose a danger to children.

There are 2 options when it comes to venting a tankless water heater; direct and power venting.

A Direct vent unit features an intake and exhaust vent since it pulls in the air outside the building. Place the power vent unit in an area with enough air quantity for combustion processes. Unlike the former model, this one requires the exhaust vent only.

The water heaters structural design also has a bigger say on the venting options available for you. Depending on the model, you can vent through the sidewall or from the roof.

Tankless water heater built with condensing technology has lower costs of installation. These heaters have polypropylene or PVC exhaust vents, which translate to greater flexibility.

For your familys safety, opt for a water heater with concentric vent design. A vent with this design has insulated intake and outtake pipes. Thus, the 2 pipes remain cool to the touch. To keep the homes aesthetics, use pipe covers and creative termination points.

If you want a thing done well, do it yourself. Napoleon Bonaparte

A week ago my hot water heater died without warning. Essentially, I was forced to live up to my homeowners responsibility of restoring life and the universe back to normal!

At first, my plan was simply to repair the old gas water heater in high hopes of a cheap fix, but you know the cliche

If you want to make the Water Heater Godz laugh. tell them about your plans of a cheap repair!

Still, you never know!

Whenever you are troubleshooting, its always better to start with the cheapest and easiest repairs first. That way you dont make the mistake of buying a brand new water heater when you couldve fixed the old one for ten bucks!

Ya know wat Im sayin

In this scenario, the cheapest and easiest fix was to take apart the burner assembly, clean it and attempt to relight the pilot. Unfortunately, that didnt work so I did a little more research.

All of the main symptoms (pilot lights, but wont stay lit after release of the pilot button) were pointing to either the thermocouple or gas control valve, otherwise known as the thermostat.

Since the free fix didnt work I moved on to the next troubleshooting idea replace the Thermocouple!!! Another let down. the cheap $10 replacement of the thermocouple was also a no go.

At this point everything is now pointing to the gas control valve. Time to drain the tank and move on to the next item on the ol checklist.

Upon further inspection and draining of the water heater, we discovered that the tank had 7 years of sediment build up. I think thats what in all probability killed the gas control valve. The water draining out of the tank was also a slight rustic color, which could indicate that the water heater has some internal deterioration as well.

In retrospect, I probably couldve fixed the old unit by installing a new gas control valve. Yet, how long would that last me before the tank rusted through and started leaking all over my garage?

After some thoughtful considerations on whether to order a new gas control valve for $135 + $42 expedited shipping, I decided it would be best to simply replace the whole unit and actually perform the recommended maintenance going forward.

I want HOT WATER!!

Technically, I was replacing a gas water heater using the existing set up and not installing one from scratch. That would be slightly more complicated!

By the way, I should be clear that I knew absolutely nothing about hot water heaters prior to this ones demise. You would be surprised how helpful Youtube can be on the subject of installing a gas water heater.

Plus, I do have some mechanical ability from working on my own cars, and helping my Father with the many household projects hes done over the years.

This is my way of saying that I had a certain degree of confidence that I could do this install on my own.

By doing my own installation I think I saved $400-700 dollars or more in installation costs.

I also learned a lot about water heaters, how they work and how to trouble shoot, remove and install them. The biggest downside was having to spend a week without hot water while trying to get it installed correctly and up to code.

All in all, I realize why plumbers charge so much to install these heavy beasts. In fact, after looking over the numbers Ive been thinking that maybe we should go into the plumbing business!!!!

I can see it now

Were NOW open for business!!! um, not really!

On second thought, installing hot water heaters daily could wear a brother out and Im not so sure Id enjoy doing this for a living. Not that theres anything intrinsically wrong with it. I definitely have a deeper respect for Mario and Luigi!

Most importantly, the final lesson is that when the hot water is gone someones gotta bring it back! Now you can either pay someone to do it for you or YOU can do it yourself. Yet in the end it is a job that has to be done. The question you need to ask yourself is.

Now for those still unsure if its worth it, weve included a play-by-play recap of the entire process and time estimations that were spent on the job.

Now be advised that this is NOT a how to article; I am just documenting the basic steps I went through for purely informational purposes. And to help you decide whether you want to tackle such a project.

Even though I saved a decent chunk of cash, I paid for it with the opportunity cost for all you inspiring economists out there! In other words, even though you might save several hundred dollars you have to ask yourself what your time is worth?

If you were to put those same hours into running your business or other money-making pursuit than the value of your time may well exceed the money youd save. In this case, it would be more advantageous to simply call a plumber.

On the other hand, if you would have just sat around watching T.V. or playing video games maybe you should get yo a$$ off da couch and install that water heater yourself!!!

Personally, I took this on as a homeowner challenge and a learning experience. Im glad I saved some money on the install, but as you will see, I definitely paid for it in time and labor putting in the new one.

On the bright side, I learned quite a few things that will help me in the future should another unit ever fail or need installed. And next time, I am certain I could do it in about half of the time. In my opinion, it was definitely worth all of the trouble!

My final thought to support doing it yourself is

Wednesday (1 hour) Took my last hot shower unknowingly or I would have savored the moment! Discovered that the hot water heater died that evening Did a little research online

Thursday (1-3 hours) Researched how to repair gas hot water heaters online Took apart the old units burner assembly Cleaned it and put it back together Tried to light the pilot and burner didnt work Pilot lights, but fails to stay lit and burner never fires Cause = either bad thermocouple or gas control valve

Friday (2-3 hours) More research on Google and Youtube Went to Lowes and bought an $8 Thermocouple Installed new thermocouple onto burner assembly Same scenario Pilot lights, but fails to stay lit and burner never fires Must be gas control valve

Saturday (2-4 hours) Tried one last ditch effort for a cheap fix Took the burner assembly out again and cleaned everything really well Still no dice, so now I know for certain it is the gas control valve Researched cost of new gas control valve.. identical part = $192 w/ fast shipping Got to take a hot shower at my lady friends place!

Sunday (3-5 hours) Drained old unit using water hose (or thought I did) Started to remove gas control valve and heard gurgling and hissing sounds Finished draining unit using buckets Could see sediment coming out of tank with water Water was a slight rusty/dirty color with sediment build up Determined that the gas control valve failure was caused by excessive sediment build up Based on research, age of water heater, cost of part, etc. decided to buy a whole new unit Started pricing new units online

This is what failed on the old water heater

Monday (6-8 hours) Took half a day off of work to install Went to Home depot, Sears and Lowes checking out new water heaters Bought a $420 Whirlpool Gas Water Heater from Lowes and supplies Cleaned garage and prepared area for removal and installation process Removed the old unit and set to the side Lifted and set the new unit into place Started thinking about how to vent and install the new unit using the preexisting set up Went to back to Lowes for venting pipes and more supplies

Tuesday (8-12 hours) Took a full day off of work to install Fully read installation instructions and watched installation videos online Researched how to vent this type of water heater Went to Carolina Supply to get parts for gas line connections Talked to some plumbers there and learned some new things about venting Went to Lowes and bought some more supplies Filled up Thermal Expansion tank Realized that I bought the wrong type of gas water heater needed a direct vent water heater not standard atmospheric Cried incessantly for one hour. Lol j/k Called around to see where I could buy a direct vent water heater. Went back to Carolina Supply and bought a Rheem 50 gallon direct vent gas water heater Took the wrong unit back down and set to the side Lifted and placed the new direct vent water heater into place Connected the cold water line and thermal expansion tank Worked on installing the venting system

Wednesday (3-5 hours) Went to Lowes again for more supplies Finished installing the venting system Connected the cold water line Connected the how water line Connected the gas pipe and union to the gas control valve Tested for water leaks, had one but fixed Tested for gas leaks using soapy bubbles none discovered Filled tank with water and fired the pilot and burner Discovered another small water leak on the hot water connection Temporarily fixed the leak Took a HOT SHOWER!!!!!!!

Heres the finished installation

By the way, Im still not finished. Got to fix the small leak, silicone the outside vent terminal, and will probably take the gas pipe connections apart and use pipe joint compound to seal them better.

Also have to box up the wrong water heater and unneeded supplies and take them back to Lowes for a refund.

Well, if youve read this far you are either really bored at work OR considering installing a gas water heater yourself!

Either way, you are now armed with some insights on whether you should attempt this job or outsource it to someone else. Hopefully, this was helpful to you in some way.

Thanks for reading our hot water heater adventure story!

And always remember what Bruce Lee has to say on the subject;

You must be shapeless, formless, like water. When you pour water in a cup, it becomes the cup. When you pour water in a bottle, it becomes the bottle. When you pour water in a teapot, it becomes the teapot. Water can drip and it can crash. Become like water my friend.

Until next time, keep the hot water flowing

Brandon

P.S. I want to send a big shot out and thank you to my brother, Cory for helping me with the installation process. No way, I could of done this without his help. Definitely a two man job!

Building jurisdictions in nearly all cities and counties require a permit to replace an existing water heater. Codes have changed, so the installation of a new water heater should meet current codes for safety purposes.

If a water heater is installed improperly there are many things that can go wrong. A few examples:

Its important to remember that there have been code changes and other requirements that may apply to the replacement of an existing water heater.

Generally, a permit for replacing a water heater is very simple to obtain. Usually a quick trip to the local building department is all that is required, plus a few dollars for the cost of the permit itself. Many building departments have a handout on installing a replacement water heater and are happy to answer any questions that you may have.

There are a few instances when two or more permits may be required.

Electrical permit

If there are situations where you have to make electrical modifications or changes, then an electrical permit may be required. For instance, if the breaker and wire size is too small to carry the electrical load of the new water heater, then a permit may be required to make the changes.

Plumbing permit

Should you need to add, extend, or modify any existing water lines to install the new water heater, then you should get a plumbing permit in nearly all building jurisdictions.

If a gas line has to be added or relocated, then a plumbing permit may be required for the modifications or changes; note that just one permit may cover both the water heater and plumbing modifications.

The short answer is yes, most of the time. If there needs to be electrical modifications, many building jurisdictions will allow you to do the modifications yourself if its your own home, but a few jurisdictions may require a license electrician to do the work. Occasionally, there may be other exceptions or requirements, however, a call to the local building department will normally provide the answers you need.

Generally a homeowner can replace an existing water heater themselves, but should obtain a permit. The safest way to know what your local building department requires is a quick call or visit to the department. Many building departments will have a handout on their installation requirements which can be very helpful; also they may have drawings or other helpful information online as well.

Do You Need A Permit To Install Or Replace An Existing Water ...

Replacing anelectric water heater requires a permit in most areas, whether the installation is performed by a professional or by a homeowner. As part of the permit process, the work will be reviewed by an inspector to ensure that both the electrical and plumbing connections are done properly and safely, and that the installation complies with the local code requirements. Here we will look at the basic electrical requirements only, as they apply to a standard tank-style electric water heater, not an on-demand (tankless) water heater.If you're planning to replace an existing electric hot water heater, now is the time to make sure the original water heater wiring is up to snuff.

Before you examine or touch the water heater wiring or electrical connections, turn off the powerto the circuit that supplies the water heater. In most cases, the circuit is served by a 30-amp, double-pole circuit breaker. Switch off the appropriate breaker in the breaker box, then use anelectrical voltage testerto make sure that the circuit is off by testing at the water heater.

The electrical wire connections for a water heater are made at a built-in junction box on the top of the water heater tank. This is enclosed by a cover plate, which you can remove to inspect the wire connections inside. Typically, the wire conductors leading to the heater are enclosed in flexible metal conduit or are made with flexible metal cable, such as metal-clad (MC) cable. This flexibility provides a little wiggle room, making it easier to replace the water heater, and it is a required feature in many earthquake areas.

With the cover plate removed, you can test for power simply by holding a non-contact voltage tester next to the wire connections; if the circuit has been properly shut off, the tester will not light up.

Electric water heaters require a 240-volt dedicated circuit, which serves only the water heater and no other appliances or devices. The circuit wiring typically includes a 30-amp double-pole breaker and 10-2 non-metallic (NM) or MC cable. At the water heater, the black circuit wire connects to the black wire lead on the water heater, and the white circuit wire connects to the white wire lead on the water heater.

The white circuit wire should be wrapped with black or red electrical tape near the connection at both ends of the circuit (at the water heater and at the breaker box), to indicate that it is a "hot" wire, not a neutral wire. Unlike standard 120-volt circuits, a 240-volt circuit carries live current in both the black and white wires. The circuit ground wire connects to the green ground screw on the water heater or to the water heater's ground lead, as applicable.

Although you won't need to deal with the thermostats or heating elements during a simple replacement of an electric water heater, it's helpful to know that electric water heaters also include inner wiring that runs from the wire connection box down along the side of the tank to two different heating elements, each controlled by its own thermostat. The heating elements, and the thermostats that control them, are contained inside access panels mounted on the side of the water heater tank. Each pair of thermostats and heating elements has screw terminals that are connected to wire leads in the water heater. You will not need to deal with these connections unless you are replacing a thermostat or heating element on an existing water heater.

Some building authorities require a bonding wire, or bonding jumper, between the hot water and cold water pipes serving the water heater. It's important to note that the bonding jumper is not required by the National Electrical Code nor the Uniform Plumbing Code, but it may be required by your local building authority.

The bonding jumper may be required to ensure a reliable bond in a metal water piping system. Some experts believe a bonding jumper helps water heaters last longer by reducing corrosion in the tank caused by electrolysis. Another function of the bonding wire is to maintain the electrical grounding pathway on the water pipes. Without the jumper, there is a break between the hot water and cold water pipes in the system, which potentially disrupts the continuous grounding pathway of the electrical system.

In any case, if you need a bonding wire, it usually consists of a 6 AWG bare copper wire connected toa ground clamp on each of the hot and cold water pipes. Eachclampshould be on a smooth part of the pipe and not too close to any fittings; the pressure of the clamp may stress soldered joints and valve connections. When replacing a water heater, it's a simple matter of making sure the jumper connections are in place after you finish installing the new water heater.

Electric Water Heater Wiring - The Spruce

A standard tank water heater can stress your plumbing pipes by the normal thermal expansion that happens during the heating process. A safety device known as a water heater expansion tank (sometimes called a thermal expansion tank) can help minimize the risk of pressure damage to the plumbing system. (This is normally not a problem on modern on-demand, tankless water heaters--only tank-style heaters are subject to this problem.)

The water heater expansion tank serves as an overflow receptacle by absorbing excess water volume created by the tank water heater whenheating water, as well as absorbing fluctuations in the incoming water supply pressure. Since water expands when it is heated due to thermal expansion, the water heater creates extra water volume every time it heats water. It's estimated, for example, that the cold water in a standard 50-gallon water heater expands to 52 gallons when heated to 120 F. This extra water volume can createexcess pressure in the plumbing system, and if the increased pressure is enough it may, over time, cause damage to the water heater, plumbing fixtures and the water pipes themselves.

In an open system where expanding water can push back into the city water supply, there is rarely any problem. However, many homes have a closed water supply system, which is a water system equipped with a one-way valve such as a backflow valve, check valve or pressure-reducing valve. In a closed system, this extra water pressure from thermal expansion can cause the most damage because the extra water pressure cannot push back into the city water supply and therefore has nowhere to go.

Most cities require that residential closed plumbing systems be equipped with expansion tanks.If you have some form of backflow preventer installed on the main water line, you may be required by law to also have a water heater expansion tank installed. Check the local building code or call the building and safety department to find out.

If you do not have a one-way valve installed on the main water line and therefore do not have a closed water system, you may still benefit from a water heater expansion tank. Expansion tanks are normally installed above the water heater on the cold water line before it enters the water heater;however, they can really be installed anywhere on the cold water line prior to entry into the water heater.Having an expansion tank helps prevent dripping faucets and running toilets by keeping the extra built-up pressure in the system from reaching the fixtures and prematurely damaging them.

Water heater expansion tank prices start at around $40and range up to nearly $200; pricing is largely dependent on the size of the tank. For most residential installations with 40- or 50-gallon water heaters, a simple 2-gallon tank is fine. The tank is quite easy to install with a normal 3/4 threaded connection. A tee fitting will have to be installed above the water heater if one is not there already.

If you are hiring a plumber to have a water heater installed, its a good idea to get a price for the installation of an expansion tankat the same time. It may not be much more than you are already paying if it is done at the same time. If you are installing a water heater yourself, consider installing an expansion tank even if it is not required, since the benefits far outweigh the work and cost involved.

Fast Water Heater Company performs installations as safely as possible to protect you and your family. Due to various injuries and accidents related to water heaters over the last ten years, most cities and counties have adopted either the 2006, 2009 or 2012 Uniform Plumbing Code (or in the case of California, the California Plumbing Code).

When we perform your installation, we will inspect your water heater and ensure it is up to date on all relevant safety codes.

Also, on the back of your invoice, you will find a list of all of the state codes that are relevant for your installation.

Some examples of common water heater codes include:

An expansion tank is required if a plumbing system is closed, which means that the back-flow that normally runs between the house and the main water supply, is blocked. However, when water is heated, it starts to expand, which causes a rise in water pressure.

The increased pressure must go somewhere. If there is nowhere for the pressure to go, it places extra stress and strain on your water heater and your homes plumbing system. Increased pressure will shorten the life of your water heater. However, expansion tanks provide relief from this excess water pressure and protect your home.

A water pressure PSI test will determine if you need an expansion tank or not.

In all our service locations, we install water heaters with earthquake straps to ensure your safety in the event of a natural disaster. Because the West Coast is in earthquake zones, all installations include straps on the top- and bottom-third of the water heater.

If your water pressure is above 80 PSI, its recommended to install a pressure regulating valve. As population density increases, water pressure goes up as well. However, high water pressure can damage your plumbing and fixtures, including your hot water heater. This can cause a premature crack in the glass lining of the water heater. Pressure regulating valves will prevent unnecessary stress on your plumbing system.

Its generally recommended, and required, to install a drip pan with a drain line beneath your hot water heater tank. Especially if you water heater is in your home or basement, a leak could cause lots of water damage. A pan and drain eliminate this possibility.

Installing a dedicated water shutoff on your water heater will allow you to turn off water to your heater, but not to your entire home. This way, if you ever need to service your water heater, you wont be inconvenienced with having to turn off the water to the rest of your house.

In some areas, the P&T (pressure and temperature relief) valve is required to be piped to the exterior. The P&T valve goes off when your hot water temperature exceeds 210 degrees Fahrenheit or 150 PSI. Some areas will allow you to pipe the P&T within 6 of a garage floor. The advantage of this is that if the P&T valve is going off, it usually means your water heater has a problem and its good to know about it. The disadvantage is that when the P&T does go off, the water comes out at very high temperature and high pressure. It is dangerous to allow children, for example, to play around the P&T valve. Due to accidents, some areas require the valve to be piped to the exterior.

In addition to placement in a certain area, the CO emissions of a water heater require it be properly vented. This will prevent any CO from entering your home and living areas. The vents must be made of a proper material and keep specific clearance from combustible materials.

Gas water heaters emit carbon monoxide (CO) when they run. 10,000 people die in the U.S. every year from CO poisoning so its important the water heater is placed in approved location. For example, in some areas, water heaters are not allowed to be installed in closets, unless they are only used for the water heater.

Codes require us to place a sediment trap on the gas line into the water heater as close to the inlet as possible. This is to prevent moisture and debris from entering the firing chamber of the hot water heater.

For electric tanks in unheated spaces, the tank must be placed on an incompressible, insulated surface with a minimum thermal resistance of R-10. This bottom board is to help prevent heat loss from the bottom of an electric water heater and can increase energy efficiency.

Important Note on Max. GPM:This column represents the maximum gallons per minute flow rate the heater can produce. Maximum GPM flow isachievable only when the incoming water is quite warm. The colder the incoming water is, the longer it must be heated to reach the thermostat setting on the tankless water heater, so the lower the GPM flow rate will be. In tankless water heater specifications, youll see information such as Flow rate @ 70F temp rise is 4.3 GPM. Thats from a unit with Max.
