Unable to get water pump to prime.
We're doing our first trip since TT was winterized. My winterization consists of blowing out water lines, draining water heater, low points and the fresh water tank. I also keep power and propane on with the thermostat set at 40 degrees all winter, as we do use it during the winter months. At no time were any valves turned to suck in antifreeze. Anyway, I filled the fresh water tank to "1/3" full before pulling out last night for our trip. Turned on the pump and opened the bathroom faucet. I can hear the pump running, but it will not pressurize the water lines or pump the water. Water works fine on city water.
I've not had this problem in the past. Does anyone have any idea how to get the pump primed?
