Emergency Leak Detection in Goose Creek, SC

Meter still running, or a high bill with no visible leak

A meter that keeps moving with every fixture off is the clearest sign of a leak you cannot see. Some homeowners describe a trickle, others a steady gallon a minute, and a bill that doubles or triples usually follows. The water can be escaping inside the house, in the yard, or somewhere in the line between the meter and your foundation, and the first job is narrowing which.

Finding a hidden leak is a diagnostic job, and the repair that follows has to meet the plumbing codes adopted locally (built on the UPC and IPC model codes). Acoustic listening, pressure testing and thermal imaging are accepted trade methods, but none of them replaces confirming the exact spot before anything is opened.

Check the cheap suspects first. A toilet flapper that leaks into the bowl can waste gallons all day without a sound, and a few drops of food coloring in the tank will show it. Also look at the ice maker line, the water softener, the water heater relief valve drain and any hose bibb left dripping.

That last step saves hours of guessing. A meter that runs after the house valve is closed points to the buried line, which is the work covered on our water service line repair page. The City of Goose Creek Water Division reads meters, so if the meter lid is flooded or the register looks damaged, tell the Division as well.

Wet ceilings, damp walls and attic leaks

A brown ring on a ceiling rarely sits right under the leak. Water runs along joists, drywall paper and pipe until it finds a low spot, so the stain can show up several feet from the source. Cutting a hole under the stain often misses the problem, which is why locating comes before any demolition.

Typical culprits include a failed shower pan or tub drain overhead, a loose supply fitting inside a wall, a corroded drain line, and an air handler or water heater drain pan in the attic. A garage ceiling that drips when the upstairs shower runs usually points to a drain or shower valve. Stains that appear only after rain point to the roof, not the plumbing.

We map the wet area with a moisture meter and a thermal camera, then run each fixture above one at a time to see which one wakes the stain. Pressurizing the supply side separately from the drains tells us whether the leak carries clean water or waste. You end up with a marked spot, so the opening in the drywall stays about the size of a hand.

Leaks under the house and in the crawlspace

If your home sits on piers or has a crawlspace, the plumbing hangs where nobody looks. Warning signs are a musty smell, sagging insulation, a soft spot in the floor, a faint sound of running water at night, and a bill that keeps rising. A sewer-gas smell in a bathroom suggests a drain leak, which is a different repair than a pressurized supply leak.

The method is methodical. We isolate the supply lines at the main, watch a gauge for pressure loss, then close off zones until the loss stops. Visual inspection with a bright light and a camera follows, checking every elbow, valve and the drain below each toilet. If the drain line is the problem, a camera run can tell you whether it needs sewer line repair or only a joint reseal.

Tell us on the call if you have stored items blocking the access hatch. Clearing it before the visit saves time, and we can tell you what to move safely. Older supply lines in galvanized steel or early plastics often leak at several points, so a second leak found during testing is a signal to price the repiping option.

Buried, yard and meter-box leaks

Underground leaks announce themselves outdoors. Look for a soggy patch with no rain, grass that is greener or taller along a straight line, sunken soil, bubbling near the meter box, or a hiss at the hose bibb. Pressure that sags at every tap while the yard stays dry can also mean a buried leak.

To find it, a pipe locator traces the route of the line. Then a ground microphone and a leak noise correlator listen for the sound of water escaping, and we mark the spot with paint or flags. Plastic pipe carries sound poorly, so on those lines a tracer gas test or a pressure test often confirms what the microphone only suggests.

Responsibility matters before anyone digs. The City of Goose Creek Water Division reads meters, maintains water lines and runs cross-connection control devices, so water bubbling up beside the meter box or in the street may be the city's to fix. Ask the Division where its responsibility ends at your address. A leak past that point belongs to the homeowner and to us.

Irrigation system leaks

Sprinkler leaks hide well because the lawn is supposed to be wet. Clues are a swampy zone, a head that never stops spraying, low pressure in one zone, or a meter that moves only when the irrigation clock runs. We test by running each zone alone while watching the meter, which isolates a cracked lateral or a valve stuck open.

The Water Division oversees cross-connection control devices, so ask if your irrigation backflow assembly needs a test. A lapsed certification can lead to a shut valve. Checking before the watering season starts avoids a dry lawn.

Pool and spa leaks

A pool that loses water faster than evaporation can still have a shell problem rather than a plumbing one. The bucket test, where a bucket of pool water sits on the step and the two levels are compared over a day, helps separate the two. We handle the pipes: return lines, suction lines, heater connections and spa remodel plumbing, using pressure tests on isolated sections. Shell cracks, liners and pump pads belong to a pool specialist.

How leak detection works: the tools and what each one finds

No single instrument finds every leak. Sound travels well in metal pipe and poorly in plastic, thermal imaging needs a temperature difference such as a hot water line, and tracer gas needs the pipe sealed and filled. The plumbers we dispatch combine two or three methods and cross-check them before anyone cuts a surface.

Ask whoever you call which of these they carry. Some callers have already paid a plumber who guessed and cut the wrong spot, and a clear answer about the method is a good sign. Tell us the symptoms and what you suspect, and we match the visit to the equipment.

Commercial leak detection for apartments, plazas and offices

Property managers call about water in a parking lot, a utility notice of a continuous leak, or a sub-meter that keeps climbing. Large sites need a method, not a hunch. We read sub-meters, close valves building by building to see where the movement stops, then use acoustic surveys and pressure tests on the section that remains.

Fire sprinkler piping is a specialty, and repairs to it usually belong to a licensed fire protection contractor, so tell us on the call if that is your system. For domestic water, irrigation and restroom groups, see our commercial plumbing page. Same-day appointments when available apply to businesses too.

After the spot is marked: repair paths and your options

Once the location is marked, the same crew can repair it, or you can take the marked spot to another contractor. The usual paths are a spot repair, a reroute around the bad section, or new pipe, and the choice depends on pipe age and how many leaks testing finds. A leak in a concrete floor leads to our slab leak repair work, and a failed section behind a wall is often a cracked pipe repair.

We dispatch across Goose Creek, and homes in neighboring Hanahan with the same symptoms get the same testing. Leaks do not follow a schedule, so nights, weekends and after-hours calls are handled the same way as a weekday morning.

My bill jumped but I see no leak

Most high bills have a cause that is not a broken pipe. A running toilet, a stuck irrigation valve, a pool refill or a water-fed appliance can use more than a hidden leak. The meter test sorts this quickly: if the meter is still when everything is off, the extra use came from a habit or a fixture, and if it moves, a leak is real.

If you do find a moving meter and an unexplained bill, ask the City of Goose Creek Water Division for the read dates on your account so you can see when use began to climb. That date often matches a repair, a storm or a new appliance, and it gives the detection visit a starting point.
