On Friday night, I got to find out what happens when your neighbor's pipes burst and they aren't home. We came home from a friend's house for a holiday get-together and my son asks why there's so much water on our driveway when it isn't raining. Took a closer look and noticed water coming out of the weep holes of the house next door. All the lights were off. Took a flashlight and looked through the front window, saw water on the floor and what looked like tiny rapids. I could hear water pouring from somewhere, too. Walked around to their driveway, looked through the kitchen window, and saw a waterfall coming out of the recessed light fixture (that was no longer recessed) and a hole in the ceiling. Turned off their water for them.
Came home, wrote a note to warn them before they entered a flooded house, and by the time I got back the lady's son was there. Never met him before, but he seemed a bit odd. As he's standing there squeegeeing water out of the front door, he asked if I knew someone who could patch up the ceiling "because it's urgent." Bro, you got busted attic pipes and two inches of water in your house, you got more urgent problems than a hole in the ceiling. I did get him the phone numbers for Serv-Pro and a neighborhood plumbing company because I figured they could get him on the right track, but he didn't seem too thankful and told me that "it's under control now." Cool, dude, if you say so. But his dad passed away a year ago and his mom goes out of the country somewhat frequently, so I don't think she's even home. It's been a few days and from what I can tell, nobody has done anything over there.
But damn if the sight of that water pouring out of the ceiling wasn't somewhat frightening. Makes me really glad we upgraded to pex when we bought this house.
