When I bought my Hatt, the potable water system was mostly disconnected. I've (attempted to) put everything back together and in the process replaced the expansion tank (broken bladder in old one), AC pump, check valves, GM pump. The AC pump short cycles rapidly untill it overheats and shuts down unless I have 3 or more faucets open at the same time, and then it runs like a champ. The new GM doesn't reach pressure and simply won't move water. I've bled as much air out of the plumbing as I can, checked for possible air leaks, moved pressure guages around, etc., etc.

If someone on the forum would be so kind, I would greatly appreciate some close up pics of the DC pump plumbing connections and maybe a sketch or detailed description of the system from the holding tank to the two pumps and expansion tank. I've got to assume that I just don't have something plumbed correctly.
