What to Do When a Pipe Bursts
If a pipe bursts, immediately locate your main water shutoff valve and turn it completely off to stop the flow. Then, turn off the electricity to the affected area, open faucets to drain the remaining water, and call an emergency plumber.
Shut Off the Main Water Supply
Your first priority is to stop more water from entering your home. Do not waste time trying to patch the pipe while the water is still running.
- Run immediately to the main water shutoff valve.
- Turn the valve clockwise (or perpendicular for a lever) until it stops completely.
- If you cannot find it, shut off the water at the street meter.
Turn Off Electricity
Water and electricity are a deadly combination. If the burst pipe is leaking near electrical outlets, appliances, or the breaker box, you must shut off the power.
- Go to your electrical panel and flip the main breaker to OFF if it is safe to access.
- Do not step in standing water to reach the panel.
- If the panel is wet or inaccessible, call the power company.
Drain the Remaining Water
Even after the main water is off, there is still water sitting in the pipes above the burst that will continue to leak out.
- Open cold water faucets at the lowest point in your house (like a basement sink).
- Flush toilets to empty the tanks.
- Open a high faucet to let air into the system and help it drain faster.
Document the Damage and Begin Cleanup
While waiting for the plumber, start mitigating the water damage and gathering evidence for your insurance company.
- Take photos and videos of the burst pipe and all damaged areas.
- Move furniture and valuables away from the water.
- Use mops, towels, and wet vacs to remove as much standing water as possible.
When to Call a Professional
A burst pipe is always an immediate plumbing emergency. Call a 24/7 emergency plumber the moment the water is shut off.
What a Plumber Will Do
The plumber will locate the damaged section, cut out the split pipe, solder in new copper or PEX tubing, and inspect the surrounding pipes for stress fractures.
Frequently Asked Questions
Should I clean up the water before the plumber gets here?
Yes, once the main water is off, removing standing water immediately is critical to prevent permanent damage to flooring and drywall.
Will my homeowners insurance cover a burst pipe?
Most policies cover the resulting water damage, though they often do not cover the cost of repairing the pipe itself. Negligence, like leaving heat off in winter, may void coverage.
How do plumbers fix a burst pipe?
Plumbers will typically cut out the damaged section of the pipe and solder or fuse a new piece of pipe into place.
Should I turn on the heat if a pipe bursts from freezing?
Yes, warming up the house helps thaw other frozen lines, but only do this AFTER shutting off the main water valve.
