Water Pump running - Event Date: 22 Mar 2019 - 30 Mar 2019

Picked up Pod from Home Owners A. parking lot to get ready for trip. Plugged in shore power then went in the house.  Came back out an hour later, and heard the water pump running.  I had forgotten to shut the pump off a few weeks ago when I flushed the sys.  Thought it only runs when calling for water What would cause it to run with all faucets closed?  Last year I had a problem with it not coming on, but that was a broken lug. Sure don't need this now getting ready to go to Cushman Scooter Rally. Thanks in advance Pod'ers.

If it's trying to pressurize the system.. but has no water it will run and run and run..

I just checked the Main Battery disconnect switch and it was off.  I turned it on, turned pump switch on and it started running.  I'm still connected to shore power. (Navy Term)  I didn't check voltage on the batteries, but I did keep them charged over the winter and have no reason to think they are bad. I'll put a V meter on them later.

If the pump head or one of the tubes or pipes froze during the winter, at or around the pump, it will crack and suck air or pump water, continuously, depending on what broke or split. 

And that is why I use the winterization valve and tube and use the pump to pump RV antifreeze through the system instead of just relying on air pressure to blow out the lines without using RV antifreeze. The RV antifreeze will also protect the pump and strainer bowl as well as the lines.
