If a pipe bursts, act in this order: shut off the water, cut power if needed, drain the lines, document the damage, and start removing water — every minute counts.
- Shutting off the water at the main is the single most important first step.
- Cut power to the area if water is near outlets or fixtures.
- Document everything before cleanup, then extract water fast.
In this guide:
The burst-pipe checklist
- Shut off the main water supply immediately — turn the valve clockwise.
- Cut power to the affected area at the breaker if water is near electrical.
- Open faucets to drain remaining water from the lines and relieve pressure.
- Document the damage with photos and video before moving anything.
- Remove water and move belongings to limit how deep it soaks.
- Call for professional help if water reached walls, ceilings, or flooring.
The detailed shutoff procedure has its own guide: the emergency water shutoff checklist.
Why speed decides the outcome
A burst supply line under pressure can release hundreds of gallons an hour, soaking drywall, insulation, flooring, and — in two-story homes — the ceiling below. The faster the water is stopped and extraction begins, the less material is lost and the lower the mold risk. For the Texas freeze context, see the Texas Emergency Water Damage Checklist.

Frequently asked questions
What’s the first thing to do when a pipe bursts?
Shut off the main water supply immediately by turning the valve clockwise. Stopping the water is the single most important step; then cut power to the area if water is near electrical, drain the lines, and document the damage.
How much water can a burst pipe release?
A burst supply line under household pressure can release hundreds of gallons an hour, quickly soaking drywall, insulation, flooring, and the ceiling below in two-story homes. That volume is why fast shutoff is critical.
Do I need a professional after a burst pipe?
If water only wet a small area you can fully dry, possibly not. But if it reached walls, ceilings, insulation, or flooring, professional extraction and drying catch the hidden moisture that otherwise leads to mold.
