This the pump I got the only one any dealer had locally. While the mounting holes are the same spacing the mount is actually further forward on the pump so I had to drill new holes to mount it.

Dave and several others at Forest River noticed I had a 45PSI flow restrictor in the wet bay while they were replacing the shocks on my bay doors.... He asked why I had that. I told him that I had read on almost every RV site that I should have one to protect our system. He then tells my that as soon as the tanks and lines are installed the system is put under 110PSI and sits that way all the way down the assembly line (several weeks) to test for leaks! He said, with a chuckle, we probably don't need the restrictor!

Did you know all water flows through the pump even when connected to city water? When I replace the pump I'm putting in a bypass valve incase I have this problem again I'm getting parts to bypass it now and will replace it when I get home in a few days. I'll try to take some pictures before and after later today.
The water does not flow through the pump when connected to shore water. Shore water does add pressure to the pump output side because that is part of the fresh water plumbing. Your pump seal has failed and that is why you had a leak at the head. Now, water can flow through the pump and back into the fresh water holding tank if the baffles (backflow preventers) have failed or have not reseated correctly. This may be old hat by now.
