I want to not heat my cabin for weeks in the winter. This year for the first time I have plumbing. I have a valve in the well that allows all the water to drain back to the well when I shut the water off....and to be sure, I blow pressured air via a faucet. Even the pressure tank seems to empty... I hope.
What about my drains....the toilet, the traps? If the water in those freeze, do the traps and toilet break? ...or does the water just expand to a higher level when freezing, with no damage occurring?
I mistakenly bought RV Antifreeze.... I see now it is for supply lines, not waste lines. I imagine it would be effective in traps too, but wonder about effect on the septic system.
Hence my question about what will happen if I don't heat the cabin and there is water in the traps. I even thought of draining the traps and toilet somehow, but then I would have sewer gas building up in cabin, no?
