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 Macomb, MO use acoustic listening devices and thermal imaging cameras to find the leak first, then open only what needs to be opened.

The biggest cost variable in pipe repair isn't parts โ it's how much structure gets opened to find and access the failure. Precise pre-repair location tools reduce that cost significantly.
Pressurized water escaping a pipe creates a characteristic acoustic signature. Our listening devices amplify ground and structure-borne sound to pinpoint a leak location within inches โ through concrete slabs, behind drywall, or under flooring. This means we open only the section of wall, floor, or slab directly over the failure.
We use thermal imaging as a complement to acoustic detection โ particularly useful for slab leaks and leaks inside insulated wall cavities where sound transmission is reduced.
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.
Every supply line repair is pressure-tested before we close the wall or floor. We pressurize the repaired section, hold the test pressure for the required duration, and confirm zero drop before considering the repair complete. You don't find out there's a second leak next week โ we find it before we pack up.
Pipe failures have different causes depending on material type, age, water chemistry, and installation history. Here's how we address each category.
Copper failures most often involve pinhole corrosion in soft copper tubing from aggressive water chemistry, failed soldered joints, or fatigue cracks at fittings in high-vibration locations. We locate the failure precisely, cut out the failed section, and install either a sweated repair coupling or a press-fit connector โ both rated to ASTM B88 standards for potable water service.
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.
This detection step routinely saves homeowners $500โ$2,000 in unnecessary drywall removal compared to opening walls speculatively.
For slab leaks, we present repair, reroute, and lining options with pricing so you can make an informed choice before any concrete is cut.
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.
Our galvanized supply lines finally gave out โ low pressure everywhere, rust-colored water at some fixtures. Masters Plumbing Service repiped the whole house with PEX over two days. They confirmed pressure and flow at every fixture before leaving, patched all the wall access points smooth, and cleaned up each work area. One year later, no issues at all.
