We're blessed to live in Minnesota. Nature gives quite a show about every three or four months - moving from spring to summer to fall to (finally).... winter.
Winter provides lots of seasonal recreational opportunities: sliding, skating, sledding, skiing, shoveling, snowball fights... uh....snow-blowing... hmm....salting sidewalks.... um.... starting diesel engines that spitefully resist your best efforts to get them going when it's less than 1 or 2 degrees.
Another great thing about living in Minnesota winters, we get yearly opportunities renew our wardrobes - swapping out last year's fleece for this year's mock fur, last year's puffy down coat for this year's heavy wool. And because we're so cheap, we indulge in the concept of putting on an extra couple layers inside to save a few dollars on the monthly fuel bill.
But all this (tongue-in-cheek-while-teeth-chattering) appreciation of winter goes out the window when you have cold-weather issues with the guts of your house.
Last weekend, we sent a little (tiny?) bit of frying pan grease through the garbage disposal and through the kitchen drain. When it hit the drain pipe that runs along an exterior wall, it instantly congealed into a thick, impenetrable and waterproof blockage in the drain pipe. Fast forward through Draino attempts, drain snakes, prayers and pipe rapping to free the clog - to this week where I decided to open the basement ceiling to deal with the problem directly.
Running a hair dryer directly against the pipe for a few minutes finally cleared the clog. Then I attempted to jam my arm up into the ceiling far enough to squirt some expandable foam against the outside of the pipe. There was no insulation against the pipe previously, so the temperature inside that drain pipe was surely below freezing.
While I had that portion of the basement ceiling apart, I also took the opportunity to fill a number of other cracks in the outside wall where cold air was pouring in - where the gas line entered the house, where the electrical service entered the house, etc. Probably still many small cracks and holes to fill, and I'm considering a larger tear-apart to properly insulate/seal, but at least I got a start.
Time will tell if the drain pipe keeps warm enough now. More sub-zero temps on the way all this week.
