Refilling water tank after dewinterizing and water exiting the exterior drain in back

jules2go

Just trying to figure this all out and again am confused! I have put the valves all back into "camping season" mode and filled up the water tank. I turned on the water pump to run fresh water through the pipes, etc but noticed that water is going straight out via that clear plastic pipe that exits to outside, underneath the hot water tank and all those pipes. When I turn the pump off, the water stops flowing out, or if I switch the hot and cold valves to closed position it stops, too. Why is this happening? When it was in camping mode before, with the pump on, water wasn't coming out under the camper. I wish there was a video tutorial on the Tab 320 plumbing system but I haven't found one yet. Thanks in advance.

@jules2goCheck the Alde water tank overflow/pressure relief valve in the Alde compartment.  The Yellow flip up handle should be down, parallel to the floor.  With the yellow valve handle in the up position, water is flowing into the hot water tank and back out through the pressure relief valve.  Closing the valve should solve your problem.
cheers

@Denny16 -- Its not up, it's parallel to the floor. Edit -- I had the cold water drain valve open :( seems to have been the problem.

@jules2go, maybe try opening and closing the yellow flapper valve a couple times and run the pump again to see if that stops the water flow.

@Bayliss I think the problem was that I had the cold water drain valve open.... for some silly reason.

I once tried to fill the water tank while the drain was open.

Glad you got it sorted Jules.
