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 Bruner, 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.
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.
Press-fit copper connections โ particularly useful for repairs in occupied spaces where open flame is a concern โ are available as an alternative to torch sweating where code permits.
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.
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.
Galvanized steel pipe was standard in homes built before the 1960s. It corrodes from the inside out โ zinc coating depletes, iron oxide (rust) accumulates on the inner wall, progressively narrowing flow and leaching into the water supply. Repairs on severely corroded galvanized are generally temporary; the pipe is failing systemically along its full run.
PEX is also the material of choice for extending or reconfiguring supply runs during remodel work. Its flexibility reduces fitting count and eliminates the need for torch work inside walls.
We also inspect upstream of the burst for additional sections that froze but haven't yet failed โ because a partially-thawed line sometimes shows multiple failure points only after pressure is restored.
Supply line leaks under a concrete slab are identified by acoustic detection and confirmed by thermal imaging. Once located, we evaluate three repair options: direct-access repair (jackhammering to the pipe, repairing the section, and patching the slab); rerouting the line through the wall framing above slab to bypass the failed underground run; or epoxy pipe lining for older copper systems with systemic pinhole corrosion.
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.

For emergency burst pipe calls, we dispatch immediately. For suspected slow leaks, we schedule at the earliest available slot and confirm before arrival.
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.
You receive a written summary of what failed, what we installed, and the warranty terms before we leave.

Water stain appeared on my kitchen ceiling from the bathroom above. I expected them to tear up the entire bathroom floor. Instead the tech ran a pressure test, found a 12% pressure drop over 10 minutes, then used the acoustic device and identified the leak at a failed sweat joint in the copper supply to the toilet โ accessible through a 14-inch drywall cut in the ceiling below. Repair was maybe $280 including the detection. I'd been dreading a $2,000 floor demo.
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.
