We have a 2327TB that the dealer just replaced the water tank in under warranty.
We're currently in a campground that doesn't have heated water connections so at night when it drops below freezing we must disconnect and rely on the stored water in the tank. Not a problem usually but, since the dealer replaced the tank, the pump will now run non-stop, pumping the tank water out of the city water in connection.
I've temporarily put an inline shutoff valve at the city water inlet to stop the pump from emptying the water tank.
I assume that this is either a dealer screw-up or, maybe the check valve at/in the pump is stuck.
The question is - where in the heck is the pump? I can kinda hear it running in the kitchen area but I'm a little reluctant to remove everything from the base cabinets and disassemble them without knowing for sure that it'll be accessible. Maybe it's only accessible from behind the water heater or from the belly.
If it's the check valve (and not a dealer piping error) I'd rather try to implement that repair myself as opposed to waiting a month for a dealer appointment. I've read that sometimes a simple tap on the pump will free up a stuck check but, you have to find the pump first
Anyone got any ideas?
