I am winterizing my new 2022 adventurer 29B for the first time. Fresh water tank is empty, opened low point water drain valves and closed them again, drained water heater, removed anode rod and switched bypass valve, and switch the pump valve over to the winterization bypass tube. Oh, I also removed the water filter, dumped the water from canister and I put the canister ( without filter) back on. I then put winterization tube into the antifreeze and with the with the water valve in the “Normal” (not tank fill) mode I turned on the pump. I could hear the antifreeze filling up the water filter canister and thought once the system was “charged” with antifreeze the pump would stop. It did not however, it sounded like it was still running. I went and checked all my faucets plus shower and toilet and all were off. I then turned them on one at a time believing there might be air in the lines or something causing this. I was able to get the pink antifreeze coming out of each hot and cold faucet plus the toilet but the pump still sounds like it is running. Funny thing is that it does not seem to be drawing any additional antifreeze! Am I missing something? has anyone else with a 29B had a similar problem? I checked inside and outside and under the coach and do not see any fluid anywhere.
