new owner of 1995 10' cabover Alaskan in excellent condition. Read the OEM manual for winterizing the water system and have a few questions since its very vague.
1. has anyone used an air pressure adapter to the outside city water connector to blow out the lines and if so what PSI is recommended?
2. I drained the tank using the rear petcock as much as I could and after running the right faucet with the electric pump on for a minute or two to remove any remaining water in the tank, I was concerned about running that pump impeller dry so I stopped when it was spitting just some water and air. Is this a matter of concern?
3. The manual says to use an RV antifreeze but they are all not the same. Some manufacturers use recycled materials of propylene glycol and who knows what from aircraft de-icing at airports. When I find "virgin" RV antifreeze like Dowfrost, do I need to run that through my lines still and pump or just put in the tank with about 1/4" of water that still remains and pour some in my P-traps? What is the recommended procedure?
thanks for the help
