Broken shower valve '73 31 ft rear bath
Can some one tell me how I can access the space behind the shower valve in my 73 31 fr rear bath AS?
Do I have to remove the Fiberglas panel above it?
There is access to the sink valves through the opening at the rear of AS for freshwater hose and dump valves but no way to get to valve for shower.
Thanks in advance for any help!
