Reminds me of the time I was working in a renovated house. I was drilling down through a sill plate into the crawl space below. I just barely broke through with the 7/8" auger when water comes gushing up through the hole. [Linked Image] Only thing it could have been was a heat pipe so I run down to the basement and turn off the boiler water feed. I went back to the shop to get my torch and plumbing tools as well as some 3/4 copper tubing and a couple of couplings. I crawled into the flooded crawl space and saw that the stupid plumber ran the pipe almost on the underside of the subfloor. Long story short I replaced the section of pipe, refilled the system and since no one was around we are the only ones who will ever know what happened. [Linked Image]

Oh, it's always good to know something about the other trades, you never know when it will come in handy!
