Winterizing 2019 GT 27

I am looking for a great DIY video to winterize our 2019 GT 27.

We used to winterize our last camper with an Air compressor, but looking for the ins/outs for our Airstream. I hear a lot about doing both Air and the pink stuff. Thoughts/Suggestions?

Thank you.

I use air and pink RV antifreeze. My dealer winterizes with air only but he noted that when he hooks up his compressed air, he completely dries out the entire piping system. He noted that most folks cannot get their systems as dry as he can and recommends using RV antifreeze after you blow out the system.

I use two gallons of antifreeze. I blow out all the lines first including the spray hose on the sink and the toilet. I hook up the compressor to the city water hookup and make sure the water is expelled from each outlet, sprayer, and low water drains. I also blow the lines with the water pressure bypass system turned in to the normal position and continue to blow with the bypass system turned in the bypass setting. I also drain the water heater from the outside drain.

After that is done, I disconnect the piping that connects to the fresh water pump. That involves unscrewing connection to the pump. I have a hose then which connects to that pump inlet and then is inserted into a gallon bottle of RV-Antifreeze. I turn on the pump and open and close each water outlet until it runs pink. Typically it only takes a little over a gallon to winterize each outlet and spray hose. What is left over I pour into each sink drain to displace any water in the drains and also pour some into the closed toilet so it sits in the bowl. Because the hot water tank is drained and the bypass valves are active, no antifreeze is pumped into the hot water tank. Any residual water left in the tank after the bottom drain valve is removed will damage the tank. I leave the drain plug out rather than putting it back in.

Using anti-freeze will make sure that no water droplets fall into low spots where they could freeze and cause damage. It's really easy to flush the piping when you dewinterize your water system in the spring. I typically sanitize the water tank each spring to kill anything growing in the tank. Pumping that mixture through the water system will also remove any traces of antifreeze and sanitize the plumbing also.

If you use RV antifreeze there is absolutely no reason to leave it in the plumbing lines. I drain it out and use air get rid of the remaining antifreeze. I collect it all and put it down the drains and into the black and grey tanks.
