A burst pipe floods a home faster than almost anything else. A pressurized line can push water across a floor in minutes, down through a ceiling, and into wall cavities you cannot see — all while you are still hunting for the shutoff.
First move: stop the water. Find your main shutoff — usually where the line enters the house, near the front hose bib, in a garage wall, or at the meter box by the street — and turn it clockwise until it stops. If the burst is near outlets or a panel, cut power to that area at the breaker first, and stay off any floor with standing water and live electricity. Then get your phone out and photograph the break and the flooding before cleanup starts.
Now call us. Someone answers live, day or night, and will stay on the line to help you locate that valve if you have not found it. Our crews run 24/7 with a 60-minute response target across Tempe, Chandler, Mesa, and Ahwatukee, and they arrive ready to extract and dry — not just to look and leave an estimate.
Polybutylene, Copper, and Why Age Matters Here
A lot of burst-pipe calls in the south-side Valley trace back to the pipe’s age and material. Polybutylene supply lines, installed widely in Chandler, Mesa, and Ahwatukee homes built in the 1980s and 1990s, grow brittle over the decades and fail without warning — often at a fitting, often inside a wall. If your home is from that era, a burst there is less bad luck than borrowed time.
Copper has its own failure mode. Arizona’s hard water, running 16 to 25 grains per gallon, is tough on pipe from the inside, and over years it can eat pinholes that spray a fine mist into a wall cavity. That kind of leak can soak framing for weeks before a stain finally shows on the surface, which is why we chase the full moisture map instead of trusting the visible damage.
On insurance: a sudden, accidental pipe burst is generally a covered loss in Arizona, while a slow leak left unaddressed is often called maintenance and denied. We document the break and the damage from the first minute so the sudden-and-accidental nature of the loss is clear. (That is general information, not a coverage ruling — your policy decides.)
