gurgling water pump

Thanks everyone for their replies and suggestions. I made it through the camping trip (4 days) and still had water in the tank. Sorry I don't know how much because it is a stainless steel one (I am hoping to replace that this winter. But anyhow I drained it on the way home due to having sand in the tank. When I got home I filled up the tank and went to the race track from Thursday through Sunday and did not hear any gurling while at the track. So I'm not really sure what the issue is/was but maybe I was running low on water in the tank and that was the problem. Once again thank you all for your help on this.

Thank you
Jim

Mine will make a fairly loud gurgling noise until the hot water heater is completely filled up.

I sometimes wish my pump would make "more noise" than it does.....maybe if it did, I would remember to turn the switch off ! I can barely hear mine running.

In addition the the above, check to make sure the valve on your winterizing intake tube (if you have one) is fully closed.

Our is open to the atmosphere at the end, to be placed into a jug of antifreeze. It just lays in the compartment of the pump. Maybe yours was bumped?

Mine sounds different right before I run out of water.

I agree. These things vibrate excessively. Check the intake side for air leaks.

Sounds like a small leak in a line on the suction side of the pump system or you are about to run out of water. If there is plenty in the tank, check all piping connections on the suction side of the system.
