Burst Pipe
Once a supply line splits open, closing the main shutoff is the only thing that stops the water, so cut it first and call before the floor framing soaks through.
When this becomes an emergency
- Water running out from under the floor or dripping through a hallway ceiling.
- A steady hiss under the house that keeps going after every tap is closed.
- A well pump that runs and runs without ever shutting off.
- Ice showing at a spigot or a crawlspace vent after a cold night.
What a pro does
Most burst lines in Alabama don't happen in the walls. They happen under the house, in a pier-and-beam crawlspace where the supply run sits in open air with nothing but a skirt of block between it and a rare hard freeze. So the plumber kills the water, then goes under with a light and follows the wet back to the split. The pipe material tells him a lot before he even sees the break: old galvanized fails at the threads, polybutylene fails at the fittings, and copper usually opens along a straight run where the ice had room to push. On a well property he checks the pump house too, since the pressure tank and the line coming off it freeze before anything inside the home does. The damaged section gets cut out and rejoined with fittings that match what's already there, mixing metals being its own slow leak. Then the system gets brought back up to pressure and watched, because a freeze hard enough to split one line has usually strained a few more.
