Well we got the water sytem cleaned out and everthing seems to work....exept when we run the hot water we get a strangled wailing sound! Air in the system? New cartridge/washer needed? Thanks all
Winnebago uses two check valves - one on the inlet and one on the outlet. One of mine started making noise last winter but the valves are such a bear to get to that I just let it go. Then after about a month it stopped making noise.
