Pipe Leak Repair in Cedar Park, TX

Homeowners call us when they see “water under the sink,” hear a drip in the wall, find a wet spot by the baseboard, or notice the water meter moving when every fixture is off. Those words point to a possible pipe leak, but the source may be a supply line, a drain connection, a valve, or a fitting hidden behind a cabinet.

We start by narrowing down where the water is appearing and where it could be traveling. A ceiling stain below a bathroom, for example, does not always mean the failed pipe is directly overhead; water can run along framing, a pipe sleeve, or the outside of a drain line before it reaches drywall.

A pipe leak should not be put off when water is active, a wall or cabinet is getting wet, or the meter continues to register use with fixtures off. Even a small leak can soak insulation, swell wood, stain drywall, and corrode a fitting while the water remains trapped out of sight.

Water under the sink

“Water under the sink” can mean a loose supply connection at the shutoff valve, a pinhole in a copper tube, a split braided hose, or a drain joint that leaks only when the basin is used. The location of the puddle, whether it is clean water or used water, and whether it returns with the faucet off all help separate those faults.

Customers also report a “hissing in the wall,” a warm patch on the floor, a wet ring on the ceiling, or a water bill that changed without an obvious reason. A hissing sound can come from pressurized water escaping at a pipe or valve, while a ceiling stain may come from a bathroom line, a kitchen line, or water that traveled across framing from another spot.

Another common call is “the meter is still spinning” after the toilets, faucets, washing machine, and irrigation controls are off. That can indicate a concealed supply-side leak, but a meter test has to be paired with checks at fixtures and shutoffs before the source is identified.

These signs can look alike from the room side, yet the repair can involve entirely different pipe, fittings, access points, and labor. We inspect the actual leak path before treating a ceiling stain or cabinet puddle as the same problem.

Leak inspection and test

During a leak inspection, we ask which room is affected, look at exposed supply pipes and drain connections, and check the water meter with fixtures off. We inspect shutoff valves, angle stops, flexible connectors, pipe joints, cabinet floors, drywall edges, and nearby ceilings for moisture, mineral marks, or corrosion.

We can use a pressure gauge to see how the plumbing system holds pressure after water use is stopped. Residential water pressure is commonly kept between 40 and 80 psi; readings above that range can place added stress on valves, hoses, and fittings. We also isolate sections of pipe where possible, since a pressure loss on one branch narrows the search.

The initial inspection and meter or pressure checks commonly take 20 to 40 minutes, depending on the number of fixtures and the access to pipes. An exposed fitting, valve connection, or short section of copper, PEX, or CPVC pipe can often be cut out and replaced on the same visit after the water is shut off and the line is drained. That repair may take another hour or two when the pipe is accessible.

If the leak sits behind tile, inside a wall cavity, under flooring, or beneath a slab, the visit may establish the likely route and the access needed before repair work is booked. We explain whether a cabinet panel, drywall opening, or other access point is needed instead of opening surfaces without a reason.

Shutoffs, walls, and pipe material

The condition of the shutoff valve matters because it controls whether we can isolate the leaking line cleanly. A valve that turns freely and seals properly makes an exposed repair more direct; a seized, corroded, or leaking valve can add replacement work before the pipe fitting can be addressed.

Access changes the scope of a pipe repair. A loose connection beneath a kitchen sink is different from a pinhole behind a shower wall, a line routed through a ceiling bay, or pipe below a concrete slab. Cabinet backs, drywall, tile, insulation, framing, and the route of the pipe all affect how we reach the failed section.

Pipe material and fitting type also matter. Copper can develop corrosion or pinholes, older galvanized pipe can restrict access at threaded joints, and PEX or CPVC repairs require compatible connectors and pipe sections. If a specific valve, manifold component, or specialty fitting has to be ordered, the repair may need a follow-up visit.

We also check whether the work affects a shared line, an exterior wall, or an area where a building approval or inspection is required. Those conditions do not make every leak larger, but they can change the materials, access work, and scheduling involved.

Fixture location and pipe access

Before calling, note the room and fixture closest to the water, such as the kitchen sink, upstairs tub, laundry box, or water heater closet. If you can see a valve, hose, or pipe connection, tell us where the drip begins and whether water continues after the fixture is turned off.

A photo of the cabinet interior, ceiling stain, exposed pipe, or water meter can help describe the leak path before the visit. For a visible valve or connector, the make stamped on the handle or the size printed on the pipe can also help us identify compatible parts.

Let us know whether the main shutoff valve works, whether water is currently running, and what access is available behind the fixture or inside the cabinet. Avoid removing drywall, tile, or a pipe cover until the source has been checked, since the visible stain may not sit below the failed fitting.
