We just purchased a 2010 Forest River Lexington GTS 255DS and when we hooked up to water the shower head leaks and does not stop. The water is pushing through the water pressure but we don't know how to get it to stop. Any suggestions would be greatly appreciated.
Sounds like the shower valve is leaking causing water to leak from the shower head. You may need to change the cartage or valve seat in the shower valve to stop the leaking.
RV showers have a shutoff valve at the shower head. If the faucets are turned on and the shutoff valve is closed, the shower will appear to have a slow leak.
Recommendation:
Point the shower head at the drain and play with the valve at the shower head. If one position has lots of water coming out, turn off the faucet(s).
