What to Do When a Pipe Bursts: Step-by-Step Guide

A burst pipe causes thousands in damage within minutes. Here's exactly what to do in the first 30 minutes to minimize damage and get it fixed fast.

A burst pipe can release hundreds of gallons per hour into your home. The first 30 minutes determine whether you're dealing with a repair or a full-scale restoration. Here's exactly what to do.

Step 1: Shut off the main water supply immediately

Don't try to find the burst pipe first. Go straight to your main shutoff valve -- typically near your water meter, in the basement, or in a utility closet. Turn it clockwise until it stops. This cuts all water flow to the house. If you don't know where your shutoff is, find it today before an emergency happens.

Step 2: Turn off the water heater

With no cold water flowing, your water heater can overheat or dry-fire. Turn the thermostat to 'Pilot' or switch off the breaker for electric units. This step is quick and prevents a second repair.

Step 3: Open faucets to drain remaining water

Open all faucets in the home to drain the water remaining in the pipes. This reduces pressure on the burst section and limits additional water coming out. Start with the faucet closest to the shutoff and work outward.

Step 4: Document and contain damage

Take photos and video of everything before cleanup -- you'll need this for insurance. Move valuables out of affected areas. Use towels, buckets, and a wet-dry vac to contain water. If water is near electrical panels or outlets, do not enter the area -- call an electrician.

Step 5: Call a plumber and your insurance company

A burst pipe is an emergency plumbing call. Get a plumber on-site to assess, repair the break, and inspect for secondary damage. Simultaneously call your homeowner's insurance -- burst pipe damage is typically covered. Document everything the plumber finds.

Bottom line

The main shutoff valve is the most important thing to know in any home. Find it now, label it, and make sure everyone in the house knows where it is.
