Can't get water pressure with pump . . .

Seems like a bad clamp would also leak water. . . I have no leaks.

Again . . . is there some kind of valve on the breather on top of the FW tank? Seems like there should be so air can get in (no vaccuum) and no water can get out.

I still believe you have an issue isolated between the pick up and pump. When on a city connection the water pump acts like a seal and does not allow water back into the tank. When the pump is on you need a completly closed, airtight system to get the suction. Why the tank is leaking could be many things. I would go over the pipe from the feed side of the pump back as far as you can to the tank and inspect all the connections. How was the unit winterized? Is that valve open still?

If only access was easier. My RV is a 4 season with the "Darco" underbelly and insulation.
Access to pipes for inspection would be a nightmare I fear.
It's looking more & more like I'm gonna be taking it to the service shop near here.

Your water pump is not in the belly. It's going to be either behind a wall in the basement storage locker, kitchen sink or in a cabinet with access. Turn it on and listen for it. If it's behind a wall like mine a few screws will give you the access you need. Who winterized the unit? Ask them where it is.

I don't think so. At least not on mine. There is a breather tube right next to the gravity fill hose that allows air into the tank, avoiding a vacuum. This is a real "stumper". Please post your findings when you get this resolved.

I have the answer!!!!!

The answer is ; I'M STUPID!!

Took it to the Jayco repair guys . . . and found out the pump was on backwards.
BACKWARDS!!

That was a $49.00 lesson. But as my wife pointed out (as she was holding back the guffaws) at least it wasn't something more serious.
The freakin' pump has an arrow on it and I thought I was following that! I now know it goes in the other direction.
