When a pipe bursts or water spreads across the floor, the first job is to shut off the water. Every minute counts. This guide shows where to find the main shut-off valve in a typical Murrieta home, how to close it safely and what to do next. Then call (951) 299-3473. We answer 24/7.

Where is the main water shut-off valve in a Murrieta home?

In many Murrieta homes the main shut-off is outside, where the water line enters the house. It is often near the front hose bib, on a wall facing the street, or next to the garage, sometimes near the pressure regulator. There is also a curb valve in the meter box, which is mainly for utility use.

House valve: A lever or round wheel on a pipe coming out of the ground near the front or side of the home.
Garage: Some homes have the valve inside the garage near the water heater.
Meter box: The valve in the box at the curb, used if the house valve fails. It may need a special key.
Fixture valves: Small valves under sinks, behind toilets and on the water heater stop water to just that fixture.

Find your valve now, before an emergency. Make sure it turns, and show everyone in the home where it is.

Technician testing for a hidden leak with detection equipment at floor level

How do I turn off the main water valve?

For a lever (ball) valve, turn the handle a quarter turn so it sits across the pipe. For a round wheel (gate) valve, turn it clockwise until it stops. Do not force a stuck valve, as old valves can break. Then open a faucet at the lowest point of the house to drain pressure.

Go to the main valve with a flashlight and gloves.
Lever handle: turn it a quarter turn until it is crosswise to the pipe.
Round handle: turn clockwise, "righty tighty," until it stops.
Open a low faucet, such as an outside hose bib, to drain the lines.
If the valve will not move, use the fixture valve closest to the leak, or call for help.

What should I do right after the water is off?

Turn off power to any wet area at the breaker, and turn off the water heater's gas or power if hot lines are affected. Move furniture and valuables out of the water, mop or vacuum standing water, take photos and video for insurance, and start drying with fans.

What if I cannot see where the water is coming from?

If water is coming up through the floor, the wall stays wet or the meter keeps moving with everything off, the leak is hidden. It may be a slab leak, a line inside a wall or a break in the main line outside. Keep the water off and call for leak detection so the source can be found.

Learn the signs of a slab leak, a leak behind a wall and a main water line leak. Our water leak detection and slab leak detection teams can find it fast.

How can I be ready for the next leak?

Label the main shut-off, keep a valve key and flashlight nearby, test the valve once or twice a year, and make sure fixture valves turn freely. Water alarms under sinks, by the water heater and behind the washer give an early warning. Save our number in your phone.

Homes in newer tracts like Copper Canyon and established ones like Rancho Bella Vista and Bear Creek often have similar valve locations, but every home is different. If you cannot find yours, our technician can show you during a visit.

Frequently asked questions

Can I turn off the water at the meter?

The meter box valve is mainly for utility use and may need a special key. Use your house valve first. In a true emergency, contact your water district if the house valve will not work.

What if my shut-off valve is stuck or leaking?

Do not force it. Use the nearest fixture valve and call for help. A worn main valve can be replaced as part of a repair.

Should I turn off the water heater when the water is off?

Yes. Set a gas heater to off or pilot, or switch off the breaker for an electric heater, until water is restored.

Will the leak stop if I turn off the main valve?

It will stop new water from entering most of the house. A leak between the meter and the house valve will keep running until the curb valve is closed.
