Just got back from Nascar races where I had to use the fresh water tank to
get water to shower/tub. Yesterday, I couldn't get the water to the tub to
fully shut off except when I turned off the pump. The faucet/diverter unit
is all plastic. I pulled the knobs and the valves appear to be plastic as
well. Can you replace the washers in those or is it better to replace the
whole shower/tub/diverter unit? Also this unit appears to be attached to the
shower wall but won't pull loose even after I unscrew the rings behind the
knobs. How do you get this thing off or do you have to pull the shower wall
loose to get to it. This unit is a 2006 Forest River Surveyor Model 291.
