I have a 2020 Big Horn 5th wheel with a Anderson Brass co water valve. The valve will not turn, I called the dealer and they said to use pliers to turn it. I called Anderson and they said the same thing. I think it is ridicules to use pliers to turn a new valve on a $80 k trailer and I do not accept that as a fix. Any one else having the same problem? There has to be something they can do to fix this problem.
