HELP!!!

We have a 2003 Alpenlite 5th wheel. Our old fresh water pump quit working so my husband installed a new one. Now even though we don't keep fresh water in the tank (we are on city water) the tank keeps filling up by itself if the valve is shut. Then it floods our front storage area. If we leave the valve open then we have a small steady stream going onto the ground under our rig.
Does anybody know where the winterizing valve is? Or have any idea what is going on?????
Thanks in advance.

I would open the freshwater drain valve on the freshwater tank. That should keep your camper from flooding until you get the water pump fixed.

Sounds like the check valve on the new pump is stuck open. Take it back out take it apart and fix it.

It sounds like the check valve that keeps city water from entering the tank has failed. BTW when he changed the pump did be put the same exact model in place of the old one? Is it possible that the check vavle was part of the old pump??
