Pipe failures range from a slow pinhole leak weeping inside a wall to a full main line rupture. Locating the failure precisely โ before opening drywall or digging โ is the skill that separates a clean, affordable repair from an expensive and destructive guessing operation. Masters Plumbing Service's pipe technicians in Ava, MO use acoustic listening devices and thermal imaging cameras to find the leak first, then open only what needs to be opened.

Our techs work on every pipe material found in Ava, MO homes, from pre-1970s galvanized to modern PEX-A crosslinked systems. The repair method matches the pipe.
Acoustic detection is most effective on pressurized supply lines. Combined with a pressure test to confirm water loss before we start, it tells us both that there's a leak and exactly where it is.
Active water leaks create temperature differentials on wall and floor surfaces detectable with an infrared camera. A slow leak inside a wall shows as a cold, spreading zone; a hot water line leak shows the inverse. Thermal imaging confirms leak presence and approximate location before any cutting begins.
Our techs are proficient in copper sweating (soldering), press-fit connections (ProPress system), CPVC solvent welding, PEX crimp and expansion fitting installation, threaded galvanized repair, and ABS/PVC drain line work. We match the repair method and material to the existing pipe system rather than forcing incompatible transitions.
Drain line repairs are water-tested by running fixtures through the repaired section and visually confirming no seepage at the repair joint and downstream.
From a pinhole copper leak behind a kitchen cabinet to a full galvanized repiping, our pipe crew in Ava, MO handles the full range.
Pitting corrosion in copper is sometimes systemic rather than localized โ a single pinhole is often the first of several to appear. When the camera or pressure test finds multiple deteriorated sections, we give you an honest assessment of whether targeted repair or full copper repipe is the better long-term answer.
We replace galvanized supply lines with copper or PEX โ either as targeted section replacement at active failure points or as a full-house repipe project. We connect the new material to existing fittings using dielectric unions where code requires to prevent galvanic corrosion at copper-to-galvanized transitions.
Cross-linked polyethylene (PEX) is the current standard for residential supply piping. Failures are uncommon but occur at crimp or clamp fittings that were improperly installed, at pipe runs exposed to UV degradation, or at locations where the pipe was kinked during installation. We repair using expansion fittings (for PEX-A) or crimp fittings with the correct ring size for the pipe diameter.
A burst pipe from freezing or sudden pressure surge requires immediate water shutoff and precise repair. We locate the failure, determine whether it's a single failure point or multiple freeze-damaged sections, and repair with a method appropriate to the pipe material โ press-fit coupling for copper, expansion coupling for PEX-A, or a mechanical repair coupling for emergency situations.
Slab leak rerouting is often more cost-effective than direct access, particularly for longer runs or under tiled floors. We present the options honestly with pricing so you can choose based on your priorities.
When galvanized supply lines are at end of life or polybutylene pipe (recalled for chronic failure) is in the home, a full repipe with PEX or copper is the permanent solution. We run new supply lines through the structure, transition all fixture connections, pressure test the entire new system, and patch access points in walls and ceilings.
We don't open walls at random. Acoustic and thermal detection tools tell us exactly where to cut before we pick up a saw.
Active leak? Our dispatcher walks you through shutting off the main supply valve while we drive to you. Describing what you see โ water stain on a ceiling, drop in water pressure, wet flooring โ helps us arrive with the right detection tools loaded.
We pressurize the supply system and monitor for pressure drop to confirm an active leak. Then acoustic listening devices and the thermal camera locate the failure to within a small area โ telling us which section of wall, floor, or slab to open.
You receive a flat-rate quote covering the specific repair based on what the detection confirmed. We open only what needs to be opened โ typically a 12โ18 inch drywall or flooring access, not a full wall section.
Repair executes immediately on approval. After the repair, we repressurize and hold a pressure test to confirm the failure is fully resolved โ not partially. The access opening is left clean for your drywall patch or left ready for your contractor.

My older home had a copper supply line fail inside an exterior wall. The thermal camera showed the wet zone through the drywall without any cutting. They opened a 10-inch section right at the pinhole, put in a press-fit repair coupling โ no torch in my wall โ pressure tested, and patched the drywall themselves. Two hours total.
Had an under-slab leak diagnosed by Masters Plumbing Service with acoustic equipment. They found the leak at 6 feet from the wall โ a single copper elbow that had developed a pinhole. Presented three options: direct slab access, reroute through the wall framing above, or copper lining. I chose the reroute โ they ran a new PEX line through the crawl space and connected at both ends without touching the slab. Pressure tested, verified no remaining drop. No jackhammering at all.
I noticed my water meter spinning with all fixtures off โ confirmed a leak in the supply system. Masters Plumbing Service ran a pressure test and acoustic scan, found a pinhole in a copper section under the slab in the utility room. They rerouted the line through the wall above slab, tested, and closed out the permit. The reroute was exactly the same cost as direct slab access would have been, but no damaged floor tile.
