Why does my sprinkler system have low pressure all of a sudden?
Short answer: A sudden pressure drop usually means something changed inside the irrigation system. It could be a broken underground pipe, leaking fitting, clogged nozzle, valve that is not opening completely, partially closed isolation valve, or a damaged sprinkler head dumping water.
The first question is whether the pressure is low on every zone or only one. If every zone is weak, we look at the water supply, backflow preventer, mainline, and system block valve. If only one zone is affected, the problem is usually somewhere between that zone valve and the sprinkler heads.
This is a common sprinkler repair call in Kingwood, especially on older irrigation systems with previous repairs or tree-root activity.
Low pressure is a symptom. Proper testing tells us where the pressure is being lost before parts start getting replaced.
What we check in Kingwood
This is a common call in Kingwood, and it is the kind of problem we test in the yard instead of guessing at from the driveway. We run the system, watch how the water is actually moving, and check the parts that cause this — before anything gets replaced. That is the same approach in the full Sprinkler Repair service page.
