What should I do when a pipe bursts?
By the Drain Guru team · Updated September 27, 2026
Quick answer
Shut off the main water valve immediately, then switch off electricity to any area where water is near outlets or appliances. Open the lowest faucets to drain the pipes, move valuables, and photograph the damage for insurance before you clean up. Then call a plumber; a burst pipe needs a proper repair, not a patch.
The order matters
- Shut off the main water. Every second counts. See how to find and close your main shutoff.
- Make it electrically safe. If water is near outlets, appliances or the panel, switch off that circuit at the breaker, but only if you can reach the panel without standing in water.
- Drain the lines. Open cold taps on the lowest floor and flush toilets to empty the pipes.
- Protect belongings. Move electronics, rugs and furniture out of the water.
- Document everything. Photos and video of the pipe and damage before cleanup help insurance claims.
- Call a plumber.
Frozen pipes
If a pipe froze and split, other sections may be frozen too. Warm them gradually with a hair dryer or warm towels, never an open flame. Keep faucets slightly open while they thaw.
Never walk into standing water if outlets or appliances in it may still be powered. Call your utility or an electrician if you can't safely reach the breaker.
More questions
Can I temporarily fix a burst pipe?
A pipe repair clamp or rubber patch and hose clamp can slow a small leak until a plumber arrives, but the main valve stays off until it's properly repaired.
