Electronic Leak
Detection Specialists
Some leaks don't announce themselves. We find them without digging.
Common signs you may have a hidden leak
Water bill spiked with no change in usage
Sound of running water when everything is off
Warm or wet spots on floors or walls
Low water pressure throughout the home
Soggy or extra-green patches in the yard
Mold or musty odors with no obvious source
Water meter moves when all water is off
Hidden Leaks Get Expensive
Water leaks are one of the most deceptive problems a homeowner can face. Unlike a burst pipe or a dripping faucet, a hidden leak can go undetected for months, slowly saturating soil under your foundation, feeding mold growth behind drywall, or wasting thousands of gallons of water every month.
The faster a leak is found, the less it costs. Electronic leak detection makes that possible without the guesswork and without tearing up floors or walls hoping to get lucky.
Signs You May Have a Hidden Leak
- Water bill that's suddenly higher with no change in usage
The sound of running water when everything is turned off
Warm or wet spots on floors or walls
Low water pressure throughout the home
Soft, soggy, or unusually green patches in the yard
Mold, mildew, or musty odors with no obvious source
Your water meter keeps moving when all water is off
The technology we use
How We Find Leaks Other Methods Miss
Electronic leak detection uses specialized equipment to locate the source of a leak precisely without relying on visible damage or destructive exploratory work.
At Yellowstone Plumbing & Drains, we use a combination of tools depending on your home's specific situation.
We don't dig or open walls on a hunch. We locate the problem first, then repair it with a plan.
Method 1
Acoustic Leak Detection
Sensitive listening equipment picks up the sound of water escaping under pressure, even through concrete slabs, soil, and wall cavities. Pinpoints the leak without opening anything up.
Method 2
Pressure Testing
We isolate sections of your plumbing system and test for pressure loss to confirm a leak is present and narrow down exactly which line is affected before any exploratory work begins.
Method 3
Moisture Meters
Handheld meters measure moisture levels inside walls, floors, and ceilings without opening them up, identifying saturated areas that point directly to the leak source.
Method 4
Tracer Gas Detection
For particularly difficult leaks, we introduce a safe, non-toxic tracer gas into the pipe. The gas escapes through the leak point and rises to the surface, where a sensitive detector pinpoints the exact location.
Don't Let a Hidden Leak Run Wild
Every day it runs, it's costing you money and doing damage you can't see.
Know where to look
Where Hidden Leaks Commonly Hide in East Valley Homes
Slab Leaks
Leaks between your meter and the home are your financial responsibility and they can be significant. If your meter is spinning when all water is off inside, this is where to look first.
Behind Walls & Ceilings
Supply lines running through interior walls can develop pinhole leaks from corrosion or joint failures, silently saturating insulation and framing for months before showing any surface signs.
Underground Yard Lines
Irrigation lines, pool supply lines, and main water service lines running through your yard are all vulnerable to root intrusion, soil movement, and material failure over time.
Water Main & Meter Lines
In Arizona's dry climate, a suspiciously wet or lush patch of yard is a telltale sign of an underground sewer leak.
Under Slabs (Commercial Properties)
High-traffic commercial buildings in the East Valley are especially susceptible to slab leaks given constant water demand and aging infrastructure common in older commercial construction.
Electronic leak detection can save you thousands on repairs and water bills. If any of these sound familiar, let's find the source before your bills go wild.
Got a notice from the city?
Your Water Bill Spiked or the City Flagged a Leak. Here's What to Do.
If your city notified you of abnormal water usage, or your bill has jumped without any change in how you use water, there's a strong likelihood you have an active leak somewhere in your system.
- 01
Check the obvious sources first
Running toilets, dripping faucets, and visible hose bib leaks. Rule these out before moving on. 02
Check your water meter
Turn off all water inside and outside. If the meter dial is still moving, you have an active leak somewhere in the system.03
Schedule electronic leak detection
We'll locate the source precisely without exploratory damage and tell you exactly what you're dealing with.04
Get it repaired and documented
We repair the leak and provide full documentation for your records and any city billing adjustment request.
City billing credits
Many East Valley cities offer one-time billing adjustment credits for verified leak repairs.
We'll make sure you have everything you need to submit that request including, repair documentation, before and after details, and licensed plumber certification.
Why act quickly
Leaks grow, small cracks under slabs widen with every soil shift
Mold can establish within 24–48 hours of sustained moisture
City billing credits require the repair to be made first
Foundation damage from slab leaks is expensive and largely preventable
