Low water pressure diagnosis is very important for cost effective performance of your sprinkler system. If you notice that your sprinkler system barely sprays any water or the heads don’t pop up when the system is turned on, the system’s water pressure is probably too low. The problem may be as simple as closed back-flow valves – check to make sure that your valves are fully open, with the handle parallel to the pipe.

Sometimes your entire sprinkler system isn’t getting enough pressure but the water pressure inside your home is fine. A sprinkler system requires much more flow than your sink or shower. 


Have you or a service provider done any digging in your yard recently? Have you put a garden stake, trellis, fence post, dog leash tether, or similar sharp object into the ground near a sprinkler line? If so, a water line may have been cut and will need to be repaired. Lines can also develop leaks.

Over time, small cracks can develop in the water lines and let in dirt. Dirt can also get into the lines during repairs and maintenance. It doesn’t take much dirt to form a clog, impeding water flow. The line will need to be flushed to the last sprinkler head of the affected zone, or repaired if there are cracked sections.
