Winterize Bypass ?

Hello trying to winterize our 2013 redwood 36rl and have a few questions. We have blown the lines out with Air and drained the HWH (Hot water heater) we started pumping antifreeze through the lines with the bypass to winter position. We now have no antifreeze getting pumped to the hot water sides of any of the faucets. Please help explain how I can run antifreeze to the Hot water sides. Also the ice maker and washer. Thanks in advance.

There is a valve on one side of the water pump that must be turned to prevent water from being pulled out of fresh water tank. That may be the problem.

Where would that valve be located on a 36RL?

We found the small black valve. That allowed the antifreeze to the cold side of faucets but will allow none to hot water side.

I don't know what is wrong. All I do is what you have done: Drain water heater, switch water heater to bypass, turn valve on pump, and use pump to pump antifreeze through the water systems.

You said you blew air through the system. Any chance you have a low point valve open??

Low water drains are on. Just no antifreeze to the hot water sides of facets. But once I turn bypass back it pumps to hot water side.

All I can add is that some RWs are not plumbed properly. Last spring we had to change our Hot Water Heater because it sprung a leak. I thought I could use the By Pass to by pass the heater and still have water in the RW but it was a no go. The way ours was hooked up we were actually getting some hot water mixed with the cold in the Wet Bay.

On our first on 2012 31sl it had a pull out hose with cap on it just stuck it in antifreeze and turned on pump... don't see a pullout hose on our 3901 wb 2019 but looks like a connector to screw in water hose bottom row in convenience bay I guess that would be it? Guess you have to take off cover to get to pump valves..
