Aaarrgghh !
Winterizing things around the house and I start looking at the pellet stove flue outside. The jackass that I bought the place from put some of the flue pipes for the pellet stove in backwards and just caulked around the joints that didn’t fit correctly. Now I’ve been redoing the whole damn thing. At least I have the flue nice a clean now.
I keep finding more crap around here that has been done completely backasswards and have to redo them.
