A stain on the ceiling under an upstairs tub, or a soft floor next to a downstairs tub, means water is getting out somewhere. A bathtub can leak from the drain, the overflow, the faucet and valve, the caulk, or the tub itself. Call (951) 299-3473 any time.
Many tub leaks can be found with simple tests. When they cannot, our water leak detection in Murrieta team uses thermal imaging and moisture meters to find the spot before drywall is cut.
Where does a bathtub usually leak?
A bathtub usually leaks from 5 places: the drain gasket under the tub, the overflow gasket behind the plate, the faucet valve inside the wall, cracked or missing caulk and grout, or a crack in the tub itself. Drain and overflow leaks happen only when the tub is used. Valve leaks can drip all the time.
| When it leaks | Likely source |
|---|---|
| Only when the tub drains | Drain gasket or drain pipe joint |
| Only when the tub is filled high | Overflow gasket |
| Only during showers | Caulk, grout, spout or shower head arm |
| All the time, even with the tub off | Valve or supply pipe in the wall |
| Floor flexes or cracks near the tub | Cracked tub or failed tub base |
