Sprinkler System Leak Detection in Flower Mound

Leak locate and repair typically $200 to $600

Irrigation leaks waste thousands of gallons before anyone notices, and in Denton County they usually show up on the water bill before they show up in the yard. A few signs you have one:

  • A water bill that jumped with no change in habits.
  • A patch of lawn that is greener or soggier than everything around it.
  • Water on the sidewalk or in the gutter when the system has not run.
  • A zone with noticeably weaker pressure than the others.
  • A depression or sinkhole forming near the meter, the backflow, or a valve box.

Mainline versus lateral leaks

The mainline runs from the backflow preventer to the valves and is under constant pressure, so a mainline leak runs 24 hours a day. Lateral lines run from each valve to the heads and only leak while that zone is running. Mainline leaks cost the most in water and are the most urgent. If you suspect one, shut the irrigation off at the backflow until we arrive.

How we find them

The tech pressure tests the mainline with the zones closed, then runs each zone and watches flow and pressure. Suspected sections get checked with an acoustic listening device and, where the wire runs with the pipe, a tracer. Once the leak is isolated to a few feet, a small section of turf is lifted, the pipe is repaired with the correct fittings for the pipe type, and the sod goes back. Most leak repairs in Flower Mound are done in one visit.

Root intrusion and age

Post oaks, blackjack oaks and cedar elms of the Eastern Cross Timbers cover Flower Mound, Highland Village and Argyle, and their roots go straight into leaking lateral joints, which is why a small drip under a tree becomes a geyser within a season. Older systems with thin-wall pipe or glued fittings that were never primed fail in clusters. If we find the third leak in the same lateral, we will tell you whether it is time to replace that run rather than keep patching it.

Call (469) 949-2629 and we will get the water stopped first and the repair scheduled second.

Leak Detection questions

How do I know it's the sprinkler system and not a plumbing leak?

Shut the irrigation off at the backflow preventer. If your water meter's low-flow indicator stops spinning, the leak is on the irrigation side. If it keeps moving, it is on the house side and you need a plumber.

Will you have to dig up my lawn?

Only at the leak itself. We locate first using pressure testing by zone, acoustic listening on the mainline, and tracer wire, then open a small section of sod that is put back when we are done.

If a zone is stuck on, close the valve at the backflow preventer first, then call (469) 949-2629. Everything else gets a date on the calendar when you call.
