We had a drain valve that would not turn on the fresh water tank awhile back so I installed a new one and thought all was well. We had filled the tank last week for a short getaway but stayed home because of rain.
I went out tonight to drain the water out & nothing comes out. I tried to blow back through the valve & couldn't. I took the valve clear off & water still won't run out. Anyone got any ideas? It is a 308FBS
