Several Possible Sources, One Systematic Process
Water showing up in your yard with no rain to explain it could be coming from a few different places: the underground water service line, a sewer lateral leak, an irrigation line, or in some cases just poor drainage redirecting rainwater from elsewhere on the property. Yard leak detection is about systematically ruling these in or out rather than guessing and digging randomly.
We start by isolating your irrigation system, since that’s the most common false alarm – a cracked line or stuck valve can pool water in a spot that has nothing to do with your main plumbing. From there, pressure testing and electronic line tracing narrow down whether the source is your water service line, followed by a sewer camera inspection if a lateral issue is suspected instead.
Depending on What We Find
- Underground water line issue → see our underground water leak detection page
- Sewer lateral issue → see our sewer lateral leak detection page
- Irrigation system issue → see our irrigation leak detection page
If it turns out to be drainage-related rather than plumbing, we’ll tell you that directly rather than pursue a repair that wouldn’t actually solve the problem.
Frequently Asked Questions
How do you know if a yard leak is irrigation or my main water line?
Isolating the irrigation system’s shutoff valve first is the quickest way to check – if the leak stops or the water meter’s leak indicator stops moving, it’s irrigation. If not, it’s likely your service line or sewer lateral.
How much does yard leak detection cost?
This depends on which system it turns out to be – irrigation issues are often cheaper to diagnose and fix than a water line or sewer lateral leak. We’ll give you a clear price once we know what we’re dealing with.
Will you need to dig up my whole yard to find the leak?
No. Pressure testing, electronic line tracing, and camera inspection narrow down the location before any digging. We excavate only at the confirmed spot.
What if the water in my yard is just from bad drainage, not a leak?
We’ll tell you that directly. Drainage and grading issues are outside our scope, but ruling out a plumbing leak is still useful information before you address it as a landscaping issue.
