Where is my sprinkler master valve?

A master valve is an automatic valve, typically an electric solenoid type valve, that is installed at the point where the irrigation system connects to the water supply. The master valve is wired to a special "master valve circuit" on the irrigation controller. (Sometimes this circuit is called a "pump start circuit".

Similarly one may ask, how do I find my sprinkler master valve?

Start at that sprinkler and try to find the valve nearby. The cheapest and easiest way to find buried irrigation valves is often to probe the soil with a thin rod, such as a long screwdriver. Often you can estimate the rough location of the irrigation valve, then find a buried valve box by probing the ground.

Similarly, how do you find out where your sprinkler lines are? As others said, find the sprinkler heads (where the water sprays out) and if you mark them on a diagram of your lot you probably will see a pattern and be able to tell where the lines are. The lines should be in straight lines between the valves.

Subsequently, one may also ask, does my sprinkler system have a master valve?

A master valve is an electric valve installed at the main water supply for the irrigation system. A master valve will greatly reduce any water loss due to a leaky station valve because the leaky station valve can only leak while the master valve is providing pressure to the system.

How do I find a sprinkler head without water?

How to Find Buried Sprinkler Heads

  1. Turn on your sprinkler system using its controller.
  2. Measure the distance between active heads using a tape measure.
  3. With the entire sprinkler system activated, identify blind spots in coverage.
  4. Probe blind spots with the tape measure and spade.
