TYPES OF SPRINKLER SYSTEMS

The water pressure in most residential systems isn't great enough to water an entire lawn at once. As a result, most systems are divided into circuits, each with its own control valve. Control valves are operated by an electronic controller that turns each circuit on and off according to the schedule you set.

The system consists of standard PVC pipe running from your existing water supply line. At each sprinkler, the pipe connects to a riser that feeds the sprinkler head. Sprinkler heads are designed to throw water in a full circle, a half circle, or a quarter circle. There are two types: rotary sprinkler heads extend above the ground permanently, and pop-up heads are designed to be flush with the ground when off, so you can mow over them.

PLANNING YOUR SPRINKLER SYSTEM

The first step in planning your system is to check with your local building department and get any permits you may need. Then make a sketch of your property, showing the locations of all structures, walkways and driveways, and trees and shrubs. Call your local utility companies and have them come out and mark the location of buried gas, electrical, and telephone lines. Note those locations on your sketch.
