Short answer
To check for a hidden leak, turn off every fixture, the irrigation controller and pool fill, then watch your water meter. If the leak indicator still moves, water is escaping. Professional leak detection uses acoustic tools, thermal imaging and pressure tests to pinpoint it without tearing up floors. Call (857) 201-2772 to have it found.

Leak detection in Phoenix and across Arizona
Hidden leaks waste water and rot cabinets, walls and floors before you see them. Leak detection uses the meter, pressure testing, acoustic listening and thermal imaging to find the leak before anything is opened up.
We take leak detection calls in Phoenix and in cities across Arizona, from Mesa, Chandler and Scottsdale to Tucson, Flagstaff and Yuma. The quickest way to start is to call (857) 201-2772 and describe what you are seeing. A person answers and talks you through what to do right away, and you get a written quote before any work starts.
What are the signs you need leak detection?
- Unexplained jump in the water bill
- Meter leak indicator moving with everything off
- Musty odor or soft drywall
- Warm floors
- Water in the yard with no irrigation running
If more than one of these sounds familiar, do not wait for it to get worse. Water damage, mold and higher bills grow quickly, and small repairs often turn into large ones when they are put off. If water is actively leaking, close the main shutoff valve first, then call.

Why do Arizona conditions matter for leak detection?
Irrigation lines, pool fill valves and slab lines are the usual hidden leaks in Arizona yards and homes. Your water provider's bill history helps show when a leak started.
Arizona water is hard almost everywhere, from Phoenix to Tucson and Yuma. Utilities such as Phoenix Water Services publish yearly water quality reports showing what is in your supply, and the Central Arizona Project delivers Colorado River water to much of central and southern Arizona. That mineral load is behind a lot of early water heater failures, crusted fixtures and narrowed drains. Low-desert heat is hard on garage and attic plumbing, while high-country cities face winter freezes.

Call (857) 201-2772What should you check before you hire a plumber?
In Arizona, the Registrar of Contractors oversees contractor licensing. Use the Arizona Registrar of Contractors contractor search to check any plumber's license status and complaint history before you hire. Ask for a written scope and price, ask what permits the job needs in your city, and keep the paperwork. Permits for major work such as repipes, sewer replacements and water heater changes are handled by your city or county building department.
Where do we offer leak detection in the Phoenix metro?
Most of our leak detection calls come from the Valley. In Phoenix that means everything from 1950s block homes in Maryvale and Arcadia to newer houses in Ahwatukee and North Phoenix. In the East Valley we cover Mesa, Gilbert, Tempe and Queen Creek. On the west side we cover Glendale, Peoria, Surprise, Avondale, Goodyear and the retirement communities of Sun City and Sun City West. Each city page covers local water supply, housing age and official resources.
Outside the Valley, we take leak detection calls from Tucson, Marana and Oro Valley in Pima County, from high-country Flagstaff, Prescott and Prescott Valley, and from river and border cities including Lake Havasu City, Bullhead City, Yuma and San Luis. Call (857) 201-2772 and we will tell you what scheduling looks like at your address.
What should you do before the plumber arrives?
- Find the main water shutoff, usually in a box near the street or on an outside wall, and know how to close it.
- If a water heater is involved, turn the gas valve to pilot or off, or switch off its breaker.
- Move valuables and rugs away from any leak, and take photos for your records or insurer.
- Clear access to the area: under the sink, the water heater closet, the yard cleanout or the attic hatch.
- Write down when the problem started and anything that changed, such as a new appliance, a recent freeze or a monsoon storm.
These steps limit damage and make the visit faster. When you call (857) 201-2772, we will tell you which of them matter most for your situation.
