Re-winterize?

[mapleman3]

So this week in Ma. Its going back to the teens to 20's at night for a few nights...the TT coming iff a camping weekend is de-winterized...do I winterize it again or just blow out the lines best I can?
I hate to go through all that again...

I'd just blow it out un-cap the drains & leave the taps open.

Even a if, the temps really drop unexpectedly, it can't hurt anything if the system is empty and the pressure is relieved.

Kind'a like when you loose power in the winter in your home. if ya open the taps it de-pressureizes the system and anything that does freeze can expand without causing damage to the plumming...

Don't forget to flush the toilet during the draining process. Those little toilet valves freeze easy. I usually drain myu hot water tank as well.

Yes going to open everything and also flush the toilet multiple times...gonna run the pump and let it get the water out of it.....
30lbs should ve more than enough air pressure or should I go less?

30lbs is plenty of pressure. Don't forget to dump some antifreeze in the traps. Also don't forget about the outside shower if you have one. I know from past experience.:banghead:

NOT to be argumentive with anyone, the traps will be ok, due to the openess
(lack of restrictions in both directions), if anything freezes it will expand along the length of the plumming. that's why one dosen't generally hear of drains freezing in the winter...;)

The little valves and such in the toilet flush mechanism are particularly prone to freeze damage. When you blow out the system, take extra care to clear the valve of water.

This is what I would do ^

I have never truly winterized a trailer in 12 years. Don't even blow out the lines...

I drain HWH, and all lines using the low point drains... Run pump dry... Disconnect flexible shower hose for inside and outside shower.... Remove water filter for kitchen spigot... Disconnect the fresh water line for the toilet and then press the handle to relieve any pressure... Leave all faucets open...

Only one problem in all those years when I forgot to disconnect the inside shower hose.

Makes it very quick to "winterize" my way... And very quick to "de-winterize".. This works because we camp all year long and if we truly winterized with the pink stuff, we'd be winterizing the de-winterizing several times a year.

YMMV

What SteveC7010, said about the Commode flush valve is important !!!

They're a make it or break it item. As Karl Malden used to be famous for saying... "Don't leave home without it!"
