In response to Re: Shower valve/pipe leaking in wall.
: I have a PP three handle tub and shower fixture in a tub/shower combo. After taking a shower, water is noticed in the basement below the shower. I've replaced the valve stems and seats in all three handles making sure to use plumbers grease and teflon tape on all threads. The leak only occurs when the hot water is on during a shower meaning I can take cold showers without a problem (burrrrr). I've ran both the hot and cold water into the tub and don't have any problems. I've enve ran the cold water through the shower and not a drip. I can't figure why only the water hot throught the shower pipe leaks. Any ideas or suggestions?

To diagnose the leak, do the following;
- Fill the bathtub from an alternate water source to the overflow waste, check for the leak.
- Turn on the bathtub faucet; hot & cold, check for the leak.
- Run the shower; don't wet the walls yet, check for the leak.
- If no leaks have developed, spray the walls with water. The leak could possibly be from defective tile grout, loose tiles, defective wall material, caulking etc.
Good Luck. e-plumber
