Scot that is a very nice and easy way to winterize your cabin/house in the U.P. The only flaw that I saw was in the third picture. It was that bottle of drain-o / acid crap. People always are dumping that worthless crap down the sewer that is clogged and all it does is rot out cast iron lines. Then we are called to unplug the sewer and get acid all over our cable making it brittle. Sorry about ranting, but I felt the need to. Your engineering is wonderful.
I've had my share of off topic rants I think that stuff is just leftover from grandpa. We are all PVC now but thanks for the tip.
