We find an irrigation or sprinkler line leak using the same acoustic and electronic listening equipment we use on slab and sewer leaks, applied to the buried irrigation lines, then confirm the exact spot with a zone-by-zone pressure test, without digging up your whole lawn to search for it. Acoustic and electronic listening narrows down the general area where water is escaping; the zone-valve pressure test then confirms which zone and section actually contains the leak before anyone touches a shovel.
Any one of these is worth a check, especially if you’ve noticed more than one at the same time:
If a rising water bill is what brought you here and you’re not sure whether irrigation is the cause, our full explanation of what drives a high water bill walks through the other common culprits too.
Before assuming it is the sprinklers, separate the three causes. A wet patch in a lawn is irrigation, a supply leak, or drainage — and a free two-day test tells you which. Turn the irrigation system off completely for two days. If the patch dries, it was irrigation. If it stays wet and the water meter moves with every tap in the house shut off, it is a pressurised supply leak rather than the sprinklers. If the meter is still and the patch appeared after rain, it is drainage, and that is a different trade.
The full version is on wet spot in the yard that won’t dry, and the meter procedure is on the water meter leak test.
We apply the same acoustic and electronic listening equipment we use on slab, sewer, and pool leaks to your buried irrigation lines, listening for the distinct sound of water escaping a pressurized line even through soil and turf.
Once we’ve narrowed the general area, a zone-by-zone pressure test isolates exactly which valve and section of line is actually leaking, so the repair targets the specific run of pipe involved rather than the whole system. This is the same non-invasive approach we use everywhere else: locate first, precisely, before anything gets dug up.
Yes, and it is one of the more common irrigation faults we are called out for. A sprinkler system leak that continues with the timer off means water is escaping upstream of the valves, on the pressurised side of the system, where the line stays charged all day whether or not a zone is running.
The usual causes are a failed valve that no longer seats, a cracked mainline between the point of connection and the valve manifold, or a fitting that has worked loose. All three behave the same way from the outside: a patch that never dries, a meter that creeps overnight, or a bill that climbed with no change in use.
There is a quick check that separates the two cases. Shut the irrigation system off at its isolation valve and watch the water meter for fifteen minutes. If the meter stops, the leak is in the irrigation system. If it keeps moving, the leak is in the house supply, and that is a different job with different equipment.
Sprinkler leak repair follows the same rule as the rest of our work: locate first, then repair only what was found. A sprinkler line leak is usually a contained repair once its position is known, because the pipe sits shallow and the failure point is small.
What we do not do is dig a trial trench across a lawn hoping to find the break. That is the method the detection equipment exists to replace.
We locate and repair irrigation and sprinkler line leaks; a full irrigation-system redesign, new zone installation, or landscaping work is outside what we do. If your system needs that kind of broader work, a leak-detection visit can still tell you honestly whether a leak is part of what’s driving the decision.
The detection visit is a flat-rate fee agreed when you book, not calculated on site once a technician has seen the size of your system. If a repair is needed, it comes as a written quote afterwards, once we know which zone, valve or line is actually losing water.
We listen for the leak on your buried lines, then pressure test zone by zone to confirm the exact spot before anyone digs.

A wet lawn or planter patch with no obvious cause, a water bill that’s climbed without an irrigation-schedule change, a sprinkler zone running weaker than the others, and mushy ground along a line run are the most common signs. See the full list above.
Yes, an ongoing irrigation leak can run for a while before it’s noticed, since it’s underground and out of sight, and that shows up as a water bill higher than your usage would otherwise explain. See our full explanation of what else can drive a high water bill →.
No. Acoustic and electronic listening equipment plus zone-by-zone pressure testing let us find the leak’s location without digging up your lawn to search for it. Digging only happens once, at the confirmed repair spot.
We locate and repair irrigation and sprinkler leaks, not full system installs or redesigns. If a broader system replacement turns out to be the more practical choice for your yard, that’s a conversation worth having, but it isn’t a service we provide directly.
