What is a master valve on a sprinkler system?
Short answer: A master valve controls the main irrigation water supply and normally opens only when the controller calls for irrigation.
In plain terms, a master valve controls the main irrigation water supply and normally opens only when the controller calls for irrigation.
The valve is where the controller’s electrical signal turns into water, so a valve problem can look like a controller problem and the other way around. Sorting out which side is at fault is the first step, and it takes testing, not guessing.
Lawns around Fall Creek deal with the same Houston heat and clay soil as the rest of the Lake Houston area, so a system that is close to right can still show problems here — dry spots in the sun, runoff on a slope, or heads that never quite throw far enough. That is why we test in the yard itself instead of guessing from the curb.
What we check in Fall Creek
When we come out to a yard in Fall Creek, we test the solenoid and the wiring at the controller, then test the valve itself, so we know whether the problem is electrical, hydraulic, or both before we replace a part. If something is off, we show you what we found before we change anything. See Sprinkler repair in Kingwood for what that visit covers.
