Water pump not pumping water

[norrisboat]

Hi everyone,

I replaced my old water pump because it leaked for my pop up camper. After replacing the old with a new one, the new one would not pump water when I turn it on. It spits out water out of the faucet and the water heater gurgles. Sounds like the water heater is blowing bubbles. I have valves to bypass the water heater and that doesn't create a different result. I thought I might have gotten a bad water pump so I ordered another new one and replaced it with the 2nd new one. 2nd new pump had same result.

I have no water leaks anywhere in the line that I can find.

My original pump was a Shurflo 2088-422-144(12VDC 7 Amps Max) and the new one is 1088-554-144(12VDC 5 AMPS Max)

Any ideas what to do to get it to pump water? Thank you.

Sounds like an empty tank or vacuum leak. Connect a hose to the pump input and a bucket of water and see what happens.
