My new winterizing trick

[Lily&Me]

Sounds like a great idea, mandolindave. Thanks for sharing.

I will be happy sometime next month, just to find I got it done correctly for the first time.

I can expand my knowledge base next year.

......for an empty HWT.


Close by-pass valves, open the pressure relief valve, attach the compressor line, open the drain petcock and blow @ 60psi for 10min.

But, I don't like flushing the water heater tank, to get antifreeze out. And I don't like repairing plumbing. I also worry about the water line that is routed in the belly from a PO repair. AND I worry about the lower tank inlet being filled with water if I just drain the tank.

In my defense….I replaced a water heater in an SOB, for a friend. NOT FUN, and I never want to tackle that job again. The tank had cracked leaving a hole that I could fit my whole hand in.

BRIAN….It never occurred to me to drain the antifreeze out right away.

Protag…..Could you give us a tutorial about the " anode " I don't know where, or what it is.

I've never actually seen this mentioned anywhere before but you might try raising and then lowering the trailer jack as far as possible when draining through the low-point valves - it is surprising how much additional water drains out.

As for the additional under-belly line it may be helpful to think about installing another low-point drain in that line.

Brian,

Exactly why I use air when Winterizing.

POI....Last season when I drained the FW tank, I had left the valve open. Proceeded to jack up the street side to remove tires for storage and and it drained for another 1/2 hr, never realized there could be that much left in it when draining level....lern & live.

Sweet Streams,

IF….you know when your last trip of the season is. Open the drains on the way home. I wouldn't try this on the highway, but I would on hilly back country roads.
