It got colder than I had thought the past couple nights, with last night getting down into the 20s. I'm hoping nothing froze. I had planned on squeezing in one last outing to I hadn't winterized yet. When I got back from our trip the weekend before last, I opened up all the drains and faucets to let gravity do its thing. I also held the terlet pedal down to let water drain out of it. Dometic says that the valve is particularly prone to freezing so they don't cover it under their warranty (new terlet).
The good news, sort of, is that I hadn't shut the rear thermostat off completely. It was trying to maintain about 40 degrees inside which it had some success in doing (the rear furnace is the smaller of the two).
Things will be warming up this week so I'll pressurize the system while I'm pumping antifreeze through it. Hopefully no problems....
Jim, Unfortunately (its been my experience) regardless if you blew water out of the RV plumbing, condensation and tiny residues that remained will flow by gravity to the lowest point and enough can accumulate to freeze and burst the pipes in ALWAYS the absolute worse and hardest place to get to grrrrrrrrrrrrrrrrr lol
Im NOT saying that's usually the case, ONLY that it can still happen if you merely blow out the lines. Theres a very very good chance blowing out will remove enough water and a freeze and burst wont happen..
I don't rest or sleep until I get the red/pink RV AFZ out all the faucets and then pour more down all the drains and traps. Sure my method requires more AFZ but I consider it cheaper then risking a busted pipe.
To each their own however, no problem
I have a 77 Dodge Lindy. My 1st year I tried just blowing the line and antifreeze in the traps. I guess some water was left in the lines and I cracked 2 water lines. My 2nd year I pumped antifreeze in through my pump, as stated above, and no problems. Good luck to everyone this winter.
i miss my 79 airstream with the "ALASKA" package! The Landau has a 10gal W/H and i need to make up a bypass bfr winterizing. We have a few months here still but TIC TIC TIC LOL!
