01A simple fix
Most tub spouts with a lift gate are a single part. When the gate wears, it stops sealing and water splits between the spout and the showerhead. A new spout of the right type and length fixes it.
The plumber checks how it attaches, because a slip-on spout put on a threaded nipple will leak.
| Lift-gate spouts | Most common in older tubs |
|---|---|
| Leaks behind the spout | Can rot the wall framing slowly |
| Galvanized nipples | Replace with brass or copper while it is apart |
02Water behind the tile
A spout that leaks at its base can send water behind the wall every time the tub fills. Over years that can rot studs and the floor in front of the tub. Look for loose tile or soft grout around the spout.
03Three-handle tubs
Older setups with a middle handle for the diverter need a new stem or a full valve replacement.
04Hand showers
Adding a hand shower often requires a new diverter or a dedicated valve position. We can advise on the best way to fit one to your existing setup without opening the wall.
