Weird water pump occurence
So I'm getting ready for this weekend's trip, and I fill the water tank. I flip on the pump to purge the air out of the lines. I can hear the pump is running, but it's not making it's normal sound or pitch. I open a tap and nothing--no pressure, no flow. The HWH is full, so it's not like there was an air pocket or anything preventing flow. I open every tap, hot and cold, and nothing, but the pump is still humming. So I open up my winterizing panel, uncap the antifreeze tube (which would seem to allow air to be sucked into the system,) and voila--the pump's pitch changes, pressure builds, and then the pump stops. I open the tap, and I have pressure/flow, pump kicks on again like it should. So what the heck was going on? It's like it couldn't get primed--almost felt like vapor lock on an old carburated V8. Thoughts? Is my pump on the way out? TIA...
