Water leaking around a plumbing fixture usually comes from a worn seal or washer, a loose connection, cracked caulk or grout, or a failing supply line. Where the water shows up, and when, can help you figure out which part is to blame.
Around Sinks
Under the sink, check the slip nuts on the drain trap, the supply lines leading to the faucet, and the shutoff valves. If water appears only when the sink is draining, the drain is likely leaking. If it drips even when the sink is not in use, a supply line or valve is the more likely cause. Water around the base of the faucet on top often means a worn seal inside it.
Around Toilets
Water at the base after flushing often means the wax ring under the toilet has failed. Water on the floor behind the toilet may come from the supply line or the bolts that connect the tank to the bowl. A toilet that rocks can break its seal, so loose toilets should be fixed quickly.
Around Tubs and Showers
Missing or cracked caulk lets water slip behind the tub or under the floor. Loose tiles or worn grout can do the same. A shower valve or drain with a bad seal can leak inside the wall, and you might only notice it as a stain on the ceiling below.
When to Get Help
Small leaks can rot cabinet floors, subfloors, and framing over time. If tightening a connection does not stop the water, if the floor feels soft, or if a ceiling below is stained, it is time for a professional repair. Turn off the fixture’s valve in the meantime.
A plumber can replace the worn seal or connection before it causes more damage. Replacing worn caulk, seals, and supply lines is part of routine fixture maintenance. Call JPR Plumbing at (833) 603-1840.
