2003 Thor Jazz Fifty Wheel

[Dawn Lewis]

I recently purchased a fifth wheel. When filling the holding tank it pours out the side of the coach. I have looked for shut off valves or something to switch in and out of the coach and could find nothing. The city water works fine, but any ideas? Don't see valves on the pump? Maybe diaphragm? Help!

"holding tank"? I presume you mean fresh water tank? (holding tank typically refers to a waste tank.)

Was it full? Water coming out of the vent line? Or was the water backing up and coming out the filler?
