A Pipe Just Burst — What Do I Do First?

Water Damage Tempe is a water damage restoration company serving Tempe, AZ and the Phoenix metro, and this is the exact sequence we’d walk you through on the phone if you called us right now with water actively spreading across your floor.

Step 1: Shut off the water

This comes before everything else, including calling anyone. Find your home’s main shutoff valve — in most Tempe homes it’s either at the street-side water meter (turn the valve a quarter-turn, or use the meter key if there’s a locking cap) or on an exterior wall close to where the main supply line enters the house. If you can locate the specific fixture or line that burst instead — under a sink, behind a washing machine, at a toilet supply line — shutting off that local valve is faster and stops the flow just as completely without cutting water to the whole house.

Step 2: Cut power to the affected area if water is anywhere near electrical

If water is pooling near outlets, a water heater, or any electrical fixture, shut off power to that circuit or area at the breaker panel before you do anything else in that room. Don’t wade through standing water to reach a breaker panel that’s also wet — if reaching it safely isn’t possible, stay out of the water entirely until someone can shut it off from a dry position.

Step 3: Call for extraction — don’t wait to see how bad it gets

This is the step people skip, and it’s the most expensive one to skip. A burst pipe typically starts a restoration job around $3,000 and can climb past $30,000 once the damage spreads to multiple rooms — and the single biggest factor separating a small job from a big one is how long the water sat before extraction started. Call (480) 531-6541 as soon as the water’s shut off. A free on-site assessment is available day or night, and getting equipment moving early is what keeps a burst pipe a contained problem instead of a multi-room reconstruction.

Step 4: While you’re waiting — move what you can, but don’t over-extend yourself

Pull furniture legs off wet flooring where you can (even a folded towel or small block under a leg helps prevent staining and wicking), move rugs and boxes to dry ground, and mop up standing water in open areas with towels if you’re able. Don’t pull up carpet or drywall yourself, don’t move heavy furniture alone, and don’t go into a room where the ceiling is sagging from water weight above — that’s a structural risk, not a cleanup task.

What NOT to do

Don’t run a space heater to “dry things faster” — it can warp flooring and, near standing water, is a real electrical hazard. Don’t assume a small leak that “seems fine” doesn’t need extraction — clean water sitting under a floor for even a day can start the same colonization clock covered in our mold-growth timeline guide. And don’t wait for your insurance adjuster before starting mitigation — most policies actually require you to take reasonable steps to prevent further damage, and delaying professional extraction can work against a claim rather than protect it (see the insurance guide for exactly how that documentation works).

Category matters for what happens next

A burst supply line is almost always Category 1 (clean) water at the moment it happens — but that classification can degrade the longer it sits, particularly in Tempe’s summer heat. Understanding the difference between clean, gray, and black water changes what’s safe to handle yourself and what isn’t; see our full breakdown in water damage categories explained.

The bottom line

The first five minutes after a pipe bursts matter more than almost anything that happens afterward — shut off the water, cut power if it’s near the leak, and call before the water has a chance to spread further. Call (480) 531-6541 and we’ll talk you through it while help is on the way.
