Trying to winterize. Pump not priming

[yankeeslover10]

2022 Rockwood 2716f. I shut off the water heater valves. This pup has the antifreeze inlet underneath by the fresh water tank. I attached a garden hose and clamped it down and turned the valve. Turned pump on and it won’t suck up the antifreeze. Any ideas or tips on what to look for? Thanks

1: Do you have the valve from the on board tank to the suction side of the pump closed? If not the pump will keep trying to suck from the tank and not the antifreeze container.

2: Have you opened the sink faucet? If not and everything is shut off the pump won’t suck anything.

3: I assume the garden hose you are using is a very short section from the valve and into the antifreeze, not something long.

AS STATED. HOSE FROM TANK HAS TO BE CLOSED........ HOSE TO RV JUG GOES TO PUMP INLET.

Valve is closed on the fresh water tank. The valve to bypass it

The garden hose has air in it causing the pump to cavatate. Use a shorter hose thats filled with water or antifreeze to start the process.

I am thinking that your garden hose is too large in diameter, even though you have it clamped, and is possibly sucking in air. The reason I say this is because my hose for winterizing is no where near the same diameter size as a garden hose. I have the same antifreeze inlet setup as you and have no issues with winterizing. The tubing I'm using is a 3/8" I.D. clear tubing. Just a suggestion.....Recheck your hose size.

I actually got it to work. I used a longer piece of garden hose and lifted it outside camper above the pump height and it worked.

Perfect!! Glad it was an easy solution. I personally like the way they have the Bypass set up attached to the water tank. Makes winterizing so much easier.
