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 Sheldon, SC 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 Sheldon, SC 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.
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.
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.
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.
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.
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.
A full repipe in Sheldon typically completes in 2โ3 days for a standard single-family home. You're without water for a portion of each day; we plan the schedule to minimize disruption to occupied rooms.
Here's how a Masters Plumbing Service pipe repair call plays out in Sheldon, SC.
For emergency burst pipe calls, we dispatch immediately. For suspected slow leaks, we schedule at the earliest available slot and confirm before arrival.
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.
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.

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.
