winterizing

Yes....I know a sad subject.

I had my dealer winterize my trailer as I was having warranty work done anyway. I'm going to de-winterize it in the spring and winterize it going forward. As noted in the many threads on the subject, there are three ways to winterize: compressed air, antifreeze, and go to Florida (I prefer this method, but, it's not in the cards)

My question is:

Unless I'm missing something, why would anyone not use the compressed air method? It is certainly more cost effective, less time required and does the job?

Always that chance that there will still be a pocket of water when using air alone. It happened to me, my first year with current unit. Now I combine BOTH methods.

1) Drain fresh water tank
2) Drain Water heater, reinstall plug.
3) Blow-out entire system.
4) Turn Water Heater by-pass valves to winter positions.
5) Run pink anti-freeze through pump until I get pink from all faucets, shower, & toilet.
6) Add cup of antifreeze to each drain (for the p-trap).
7) Blow water out of Tornado Flush (black tank sprayer).

Entire process takes less than 30 minutes.

In the summer, I flush everything WELL before opening Water Heater valve.

I do like Fire Instructor, but then I blow the lines a 2nd time. Any "pockets" of liquid in the low points will be antifreeze. Since I already have thing set up for blowing the lines, the 2nd time gets me already for next spring.....I don't have to blow then lines then when getting ready to sanitize the water lines.

I have always been a little fearful of just blowing the lines......air can blow over low spots, leaving water in places. Fire Instructor's post confirms that fear for me.

I do the same .

You have to buy atleast a gallon of antifreeze for traps....... so what's another two gallons to blow through the lines .

My lower than drain low point was at the bottom pipe of my water heater. After I drained the water heater, I had closed the two valves and opened the bypass, then run the pink stuff... What I didn't realize was that the bottom pipe still had water, and when it froze, it broke the back-side fitting of the lower bypass valve. The real hassle was being enough of a contorsionist to climb and reach behind the water heater far enough to fix it!
