Thanks for all the suggestions. It is definitely on the inlet side. I have no idea what happened but I have leak right at the top of the fresh water tank. I am thinking where the fresh water line enters the tank. I had two thirds of the tank filled and no water leak. When I filled it to the brim a little water leaked out. I checked the pump by running water through the winterizing hose and it worked fine so.... I replaced the pump for no reason. [emoticon] Works fine with city water inlet though.

[emoticon] so then did you switch the winterizing valve to suck the water out of the tank?

So now you need a product to fix the leak. Should not be difficult once you determine what will bond to area of the leak.

So does it work now?

A leak there should not cause the problems you are experiencing. The tank does not need to be pressurized. You are drawing air somewhere in front of the pump or the pump itself.

Exactly^^^^^
Tank has a vent so a small crack/hole on top of tank would NOT affect pump being able to suck water from tank.

Air leak on suction line between tank and pump, strainer gasket, winterizing set up etc allowing air into pump ---hence no priming/pumping


Is it time for your medication or mine?

Check the in line screen cover. Those little clear plastic covers can crack when frozen despite having rv antifreeze in the lines. Ask me how I know.

If you have a winterizing hose. Do you have a valve 3-way type that you use to select it? IF so the valve is suspect (I mentioned it earlier) to test plug the winterizing hose or seal the intake by whatever means you like.. if that fixes it the valve is the problem.


Home is where I park it.

Interesting ideas. I have been working mon tues and wed. I will take another look Thursday. You see when I filled the fresh water tank all the way up instead of just 2/3 full, water actually leaked out of the tank area. Meaning to me something has come apart, or cracked. How I do not know because I am always very anal about winterizing. Somewhere at the top of the tank probably where the fresh water tube connects there has to be a problem.
When I find it I will update! Thanks

A leak at the TOP of the tank will not affect the water pump. It's supposed to have a "Leak" (Note the quotes at the top to let air in as the tank empties, it's called a vent.

A water tank vent doesn't leak into the basement. My tanks vent is right beside the fill.
