I unwinterized my camper this spring and used the city water intake to flush everything. I fill my fresh water tank and added a little chlorine to clean it out and then drain it.

When I went to use the fresh water tank for the first time... I filled the tank and turned on the pump. The pump started running and wouldn't stop. Finally I realized I hear water running and went outside to find the water flowing out of the fill-up spout on the outside to the camper.

Again the system works fine with not leaks using city water and it doesn't leak using the pump... IT JUST PUMPS BACKWARDS!!!

Any tips... I have a new water pump being shipped my way. It is a 1997 RV in very good shape with a shurflo pump.

Any info before it gets here would be great.

Check your wiring to make sure you haven't got the + and - reversed. Just a thought.

that was my first thought as well but if the pump wasn't removed and then reinstalled i don't see how that can be.

Some how you dislodged the city water check valve at your hose hookup fitting. If you put a plug in that connection you will find your pump is just fine. You may be able to reset the check valve with your finger as long as there is no pressure on the system. Hope this helps, Jim


This was my thought as well. Well, it looks like your possibly going to have a reserve water pump in stock now. This will make you or some other RV'r a very happy camper one day.

Is it coming out the City connection? There is a check valve there that might be stuck open allowing the pumped water to escape.

Probably a combination of problems. Reverse polarity on the battery bank for starters, plugged vent pipe on the FW tank, for another. Probably get by with the plugged vent pipe but may have blown the reverse polarity fuses MOST converters have when wired backwards and they'll need to be replaced. You should also note that the slide room works in reverse order (push out and get in) and your stereo may not work at all. Lighting would be unaffected and often the fridge will not work because the control board is powered backwards. Always mark your battery leads or remember that white is usually the ground wire.

A lot of RV'rs have winterized their system with RV antifreeze, then to be extra sure that all the plumbing was winterized, they pushed in on the check valve at the city water connection. This will dislodge the check valve if it is under pressure, and when the pump is turned on the next time, water sill shoot out. I did the same thing. Had to take the valve out, but I was able to figure out how to reset the washer in the valve to correct the problem, rather then replacing the valve.
