I am in the South. Winters are not really extreme. Probably some 4 or so times it will get below 10, maybe a dozen or so nights it will get down to 17-20. Example, as of now, Nov 29, we have not gotten below freezing.
I wish to winterize a house where the water and gas is off.
P-traps in sinks and toilets, etc. Is there any difference in RV antifreeze and regular auto anti-freeze for that purpose. Pipes are mostly PVC.
Water heater is drained by the bottom c*ck. At that I imagine there is a little water left in the bottom.
Water lines are drained to the extent that they will by opening lowest outside faucets.
What else? How much anti-freeze per trap? Do I need to final flush the toilets and drain the water closets or will auto antifreeze be safe in there and in the bowls? (I need it to look as good as possible because I am trying to sell the house)
Thanks,
FACE
