Professional Leak Detectionin Tucson, AZ
We find the leak before anyone starts cutting.
Unexplained high water bill? A meter that won't stop moving? Priority Rooter & Plumbing uses pressure testing, acoustic listening, and thermal imaging to pinpoint hidden, underground, and slab leaks across the Tucson area — then repairs them at a flat, up-front price.

How precisely electronic locating narrows a hidden leak
Detection appointments available across the Tucson metro
Every kind of leak you can't see.
If water is escaping somewhere between your meter and your fixtures, we can find it.
Hidden Water Leaks
Leaks behind drywall, under cabinets, and inside chases that never show a puddle until damage is done.
Underground Line Leaks
Yard and main water line leaks under gravel, pavers, decomposed granite, and desert landscaping.
Slab Leaks
Supply lines running through or beneath a concrete slab — common in Tucson's slab-on-grade homes.
Wall & Ceiling Leaks
Stains, bubbling paint, and soft drywall traced to the exact pipe or fitting behind it.
Plumbing System Leaks
Angle stops, hose bibbs, water heater fittings, irrigation tie-ins, and pressure-side connections.
Hot Water Line Leaks
Warm spots on the floor and a recirculation line that never stops running usually mean a hot-side leak.
Clues that water is going somewhere it shouldn't.
Recognize any of these? A detection visit is far cheaper than the damage a slow leak causes over months.
Unexplained high water bill
A bill that jumps with no change in habits is the most common reason Tucson homeowners call us.
Water meter keeps moving
With every fixture shut off, the meter's low-flow dial should sit still. If it creeps, water is escaping somewhere.
Running water you can hear
A faint hiss or trickle inside a wall or under the floor with nothing turned on.
Warm patches on the floor
A hot spot on tile or concrete points to a hot water line leaking under the slab.
Musty smell or mold
Persistent damp odor in one room means moisture is feeding something behind the surface.
Wet soil or lush green patch
In our dry climate, one unexplained damp or green area in the yard almost always means a buried leak.
Diagnostics, not demolition.
Several methods used together turn "somewhere in the house" into a spot we can mark with a pencil.
Pressure Testing
We isolate and pressurize sections of your plumbing to prove which line is losing water before we open anything.
Acoustic Leak Listening
Ground microphones and amplified listening equipment pinpoint the sound of pressurized water escaping a pipe.
Thermal Imaging
Infrared scanning reveals temperature differences from wet insulation, hot water lines, and saturated framing.
Moisture Mapping
Pin and pinless moisture meters map how far water has traveled through drywall, wood, and flooring.
Line Tracing & Locating
We trace and mark buried water lines so digging happens in one small, correct spot.
Meter & Isolation Testing
Meter readings plus valve isolation separate irrigation, pool, and house leaks from one another.
From high bill to marked spot.
A repeatable sequence that rules out the wrong answers before we commit to one.
Talk through the symptoms
Bill history, sounds, stains, and when it started tell us where to focus first.
Verify a leak exists
A meter and pressure test confirms water is being lost — and roughly how much.
Narrow the zone
Isolation testing separates the irrigation, pool, main line, and interior plumbing.
Pinpoint the spot
Acoustic, thermal, and moisture equipment locates the leak within inches, not rooms.
Mark and explain
We show you exactly what we found, what caused it, and what repair options exist.
Repair on your approval
Once you approve a flat-rate quote, we repair it — often the same visit.
Why locating first saves you money.
Cutting into drywall, tile, or a concrete slab to hunt for a leak is expensive guesswork. Pinpointing the leak first keeps the repair — and the restoration afterward — as small as possible.
Once we've located it, we walk you through the repair options: a spot repair, re-routing a slab line overhead, or replacing a section that's clearly at the end of its life. You get a flat price for each before anything starts.
