Yeah, well, the fun never ends here at Casa de los Congelados.
We picked up some electrical heat tape and insulation for the toilet pipe. The Sergeant would've installed it for me, but it turns out he can't get into the crawlspace at all. Much less around the bracing that Pascal put under the tub. (And let me tell you, I have new-found respect for Pascal.)
So here you see the toilet pipe heading up into the wall. I attached the heat tape as high as I could, then ran it down to where it meets the cold water line, over to the tub, then back along the hot water line and over to the cold again. The sensor is that orange bulgy bit on the right.
Once that was done, I wrapped the whole shebang in insulation tape. When the sensor detects a chill, it turns on the heat tape.
Just that little bit took me about two hours, mostly one-handed because the space was so tight. I am cursing those old-timey homebuilders for not leaving enough space to even sit up in.
And in case you're wondering, the low was -19. The previous record for this date? -6.
Oh, for you Celsius people, that's -28.3!
