Burst pipe first steps

What it means

What this usually means

A burst pipe can release water quickly into walls, ceilings, floors, or crawlspaces. Fast shutoff limits damage before repair can begin.

• water spraying
• ceiling drip
• wall swelling
• meter spinning

1. Step 1

   Close the main shutoff.

2. Step 2

   Avoid electrical hazards.

3. Step 3

   Open a low faucet.

4. Step 4

   Request burst pipe help.

Mistakes to avoid

What not to do

• Do not leave pressure on the line.
• Do not touch wet breakers without safety.
• Do not rely on tape for active pressure.
• Do not wait if water is inside walls.

Urgency

When this becomes urgent

• water is still flowing
• ceilings bulge
• electrical fixtures are wet
• the shutoff valve will not close

Decision support

How to prioritize the first few minutes

The first priority with a burst pipe is stopping the water, not finding the break -- shutting off the main valve buys time to assess damage safely before repair work starts.

• Go straight to the main shutoff if water is spreading quickly rather than searching for a smaller valve.
• Treat any water near outlets, switches, or plugged-in equipment as an electrical risk first.
• Open a low faucet after the shutoff to relieve remaining pressure in the line.
• Photograph visible damage once it's safe, since it helps both the plumber and any insurance claim.

Provider diagnosis

What a provider may need to know first

• Whether the main shutoff is already closed and water flow has stopped.
• Where water is appearing -- ceiling, wall, floor, or exterior.
• Pipe material if visible or known from the home's age.
• Whether ceiling, wall, or slab access will likely be needed.

Safety boundaries

What not to do right after a pipe bursts

• Do not leave the main water on while you look for the source.
• Do not touch wet switches, outlets, or breaker panels.
• Do not rely on tape or clamps to hold back active pressure.
• Do not wait if a ceiling is bulging or sagging.
