First move, always: stop the water. Every minute the main stays on adds gallons and pushes water deeper into floors and walls.
Step by step
- 1. Shut off the main water valve. This stops the source. Everything else is secondary until the water is off.
- 2. Cut power to affected rooms — but only if you can reach the breaker without standing in water. If you can't reach it safely, leave it and call an electrician or the utility.
- 3. Document everything. Take wide and close-up photos and video of every affected area before you move or clean anything — your insurer wants the original damage on record.
- 4. Move valuables and electronics to a dry area, and lift furniture onto blocks or foil to protect it and the floor.
- 5. Start removing water. Mop and towel what you safely can, but don't use a household vacuum on standing water. Professional extraction removes far more, far faster.
- 6. Call for help. The faster extraction and drying begin, the less material has to be torn out and replaced.
Where your main shutoff is
In most Tucson homes the main shutoff is on the street-facing side of the house, often near an outdoor hose bib, in a garage, or near the water heater. Many homes also have a meter shutoff at the curb. It's worth finding and testing yours before an emergency — a stiff, corroded valve you can't turn in a panic is a common reason damage gets worse.
Why pipes burst in Tucson
Hard freezes are less common here than in colder climates, but pipes still burst — from aging galvanized or polybutylene plumbing, high water pressure, corrosion from hard water, and ground movement from caliche soil stressing lines. And during winter cold snaps, exposed or exterior pipes (and those in unheated garages) can freeze and split, especially if they weren't insulated.
What not to do
- Don't wait to "see if it dries" — the 24–48 hour mold window starts immediately.
- Don't run a household vacuum over standing water.
- Don't use electronics or appliances that got wet until they're checked.
- Don't throw away damaged items before documenting them for your claim.
Most burst-pipe damage is covered by homeowners insurance as a sudden, accidental event. Document thoroughly and contact your carrier early.
Common questions
FAQ
What's the first thing to do when a pipe bursts?
Shut off your home's main water valve immediately — stopping the source comes before everything else. Then cut power to affected rooms if you can reach the breaker safely, document the damage with photos, move valuables to a dry area, and start water removal. The faster the water is off and extraction begins, the less damage you'll face.
How do I shut off the water to my house?
Find your main shutoff valve — in most Tucson homes it's on the street-facing side of the house, near an outdoor hose bib, in the garage, or by the water heater, with a meter shutoff at the curb as a backup. Turn it clockwise (right) to close. It's worth locating and testing yours before an emergency so it isn't stuck when you need it.
Do pipes freeze and burst in Tucson?
It's less common than in colder climates, but yes — during winter cold snaps, exposed or exterior pipes and those in unheated garages can freeze and split. More often, Tucson pipes burst from aging plumbing, high water pressure, hard-water corrosion, and ground movement from caliche soil stressing the lines.
Is a burst pipe covered by homeowners insurance?
Usually yes. A burst pipe is a sudden, accidental event, so standard Arizona homeowners policies generally cover the resulting water damage minus your deductible — though typically not the cost of the failed pipe itself. Document everything and contact your carrier early to protect the claim.
How much does burst pipe water damage cost to fix?
A burst pipe affecting one or two rooms typically runs $1,500–$4,000 for extraction and structural drying, assuming it's caught quickly. If the water sits and reaches drywall, flooring, and cabinets, costs climb with the added demolition and rebuild.
