Being divorced and owning my own home, I cant afford anyone to fix stuff so I am trying to learn on my own. I think the WORST is plumbing.....even sink and bathtub drain stink to high heaven when you clean them. Sticking your hand down the toilet isnt fun....I guess I'd charge alot for that, too, lol.
The hot water heater seems high though, but it takes along time to do. Or maybe it was just us, we didnt know what we were doing!
