Had a pipe burst in my crawl space last Sunday...
I was just getting ready to watch the Seahawks game when I heard water running under the house. Went down there with a flashlight and saw a copper pipe had split right at a joint, spraying water everywhere. The crawl space is only about 2 feet tall, so I had to crawl on my belly through mud and insulation to reach the shutoff valve. Took me 20 minutes to get it turned off while water kept soaking through my jeans. Ended up calling a plumber out on a Sunday, cost me $350 just for the emergency visit plus another $200 to fix the pipe. He said the joint had corroded from some old flux they used back when the house was built in 1998. Has anyone else dealt with surprise pipe failures in their crawl space?
