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

By the Ironwood Plumbing OC team · Updated 2026-11-02 · Plumbing tips for California homeowners

A burst pipe can release hundreds of gallons an hour. Acting in the first five minutes makes the difference between a repair and a renovation.

1. Shut off the main water valve

It is usually near the street in a box, or where the pipe enters the house. Turn it clockwise. Everyone in the household should know where it is.

2. Turn off the water heater

With the supply off, the tank can overheat. Switch gas units to "pilot" and flip the breaker for electric units.

3. Open faucets to drain the lines

This relieves pressure and stops the flow from the break.

4. Cut power if water is near outlets

Water and electricity do not mix. Shut off the breaker for affected rooms.

5. Call an emergency plumber

Our burst pipe repair team responds 24/7 across California. We cut out the failed section, replace it, pressure-test the system and check for other weak spots.

6. Document everything

Photos and video help your insurance claim. We provide a written diagnosis and invoice. For slow leaks found afterward, our water leak repair team can help.
