A burst pipe in Newark can soak a house in minutes, and every extra hour adds to the cleanup. The steps below are meant to be read quickly, then used.
If you are wondering how to shut off main water valve hardware you have not touched before, read the steps first. They take under a minute once you know where to look.
Before We Arrive: Shut Off Your Water
Start with these steps while you wait for help.
1. Find the main shutoff valve. It is often on the garage wall or at the front of the house. Turn it clockwise until it stops.
2. Use the ACWD meter shutoff if needed. If the house valve will not turn, a meter key can close the shutoff at the meter box.
3. Turn off the water heater. This protects the tank if the supply is cut off.
4. Switch off power to wet areas. Only do this if you can reach the panel without standing in water.
5. Call us and describe what you see. We give you the next step on the phone.

Why Emergencies Happen Here
A burst line under a Newark slab or in a second floor wall can soak floors in minutes. Part of Newark is within 5 km of the Hayward Fault, so owners should know where their shutoff is before a quake.
- Old copper pinholes: Original copper from the 1970s can fail suddenly after years of slow wear.
- Winter storms on clay: Heavy rain moves soil, which can crack buried lines.
- Fault shaking: A quake can shift a fitting and start a leak.
- Water heaters: Old tanks and connections fail without warning.
Five Steps From Burst Pipe to Plan
- Call and describe the problem: Tell us what you see and whether you have shut off the water. We give a price range and next steps.
- Inspect and test the property: The tech isolates each line and tests pressure to find the failed section.
- Pinpoint the exact spot: Listening gear and a thermal camera mark the break so the opening stays small.
- Review the report and quote: You see the cause, photos and options, with a firm price before the repair starts.
- Repair and clean up: Our licensed California plumbing team handles a temporary fix or full repair, then cleans up.
