TYPES OF SPRINKLER SYSTEMS
05/20/12
* 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.
