Split supply pipe spraying water inside a sink cabinet with a warped cabinet floor

A burst or split pipe can release hundreds of gallons an hour. In Florida, common causes are aging copper or galvanized pipes, failed fittings and supply lines under sinks, toilets and refrigerators.

1. Shut off the main water valve

It is often in a box near the street, on the side of the house where the line comes in, or near the water heater. Learn where yours is before you need it.

2. Make it safe

  • Do not touch outlets, switches or appliances while standing in water.
  • Turn off power to wet areas at the breaker only if you can reach the panel from a dry spot.
  • If a ceiling is sagging from water above, keep everyone out from under it.

3. Drain the lines

Open a faucet at the lowest point in the house to drain remaining water from the pipes.

4. Document, then remove water

  • Take photos and video of the burst pipe and all damage.
  • Remove standing water, move belongings out, and open cabinets.
  • Run AC and fans, and a dehumidifier if you have one.

Frequently asked questions

Should I call a plumber or a water damage company first?

Shut off the water first. Then you often need both: a plumber to repair the pipe and a restoration company to remove water and dry the structure.

How fast does mold grow after a burst pipe?

The EPA notes mold can begin growing on wet materials within 24 to 48 hours, which is why fast drying matters.
