Plumbing Leak Repair
Quick answer
Most household leaks come from a supply line or shutoff valve, a faucet cartridge or washer, or a drain connection. Dry the area, test each part, and close the nearest shutoff. If the leak is inside a wall or ceiling, or you cannot stop it at a fixture valve, call (888) 217-6781 to reach a plumbing company in your ZIP.
Follow the short menu, then your 5-digit ZIP. The line goes quiet for a few seconds while it connects; stay on. If it does not connect, call once more: companies taking calls change minute to minute.
Signs you need a plumber
- Water in the cabinet under a sink
- A faucet or tub spout that keeps dripping
- Stains or bubbling paint on a wall or ceiling
- A water bill higher than usual
- The water meter moving with every tap off
Water coming through a ceiling or out of a wall means a pipe is leaking where you cannot reach it. Close the main shutoff and call.
What to check before you call
- Dry everything, then lay paper towel under each connection to see which one drips
- Drip with the faucet off: supply line or valve. Drip while draining: the drain or trap
- Check the water meter with every fixture off to test for a hidden leak
- Know where your main shutoff is before you need it
What the plumber does

Leak repair: common questions
Why is there water under my bathroom sink?
It comes from one of four places: the supply lines and shutoff valves, the faucet, the drain (pop-up, tailpiece or P-trap) or the drain flange seal. A drip with the sink off points to the supply side.
How do I know if I have a leak inside a wall?
Turn off every fixture and watch the water meter. If it still moves, water is going somewhere. Stains, soft drywall or a musty smell show roughly where.
Is a dripping faucet worth fixing?
YesThe worn part is usually a cartridge, washer or seat, and a steady drip adds up on the water bill and wears the valve further.
