Water Pump Issue

[LoveCamping]

My wife & I have a Heartland North Trail NT21FBS camper. I de-winterized our camper last week & put 3 or 4 gallons of water in my fresh water tank. I turned on the water pump & can hear it run, but no water comes out. I made sure my extra hose, used for filling w/ anti-freeze was closed off, but I can't see any reason for the water not flowing. The pump is a Pentair Shurflo 4008 RV revolution. Any suggestions on what to check would be appreciated. (I did hook up an outside water source & verified all faucets works, along w/ the water heater.)

Thanks,

Add more water. 3 or 4 gallons barely will cover the bottom of the tank. Fill it atleast 1/2 full.

Thanks "Hoefler". I'll give that a try. It was working perfectly fine when I winterized the unit last year.

Also the last two water failures I had were from the anti freeze not quite doing its job. My pump worked when it was put away, and croaked over winter. I now not only run antifreeze thru the system, but used compressed air to blow it out too. The good brands of antifreeze will freeze solid if cold enough.
