Why Every Homeowner Should Know How to Shut Off Their Water

Most homeowners know where their thermostat is. Most know where their electrical panel is. But surprisingly, many people don't know where their home's main water shut-off valve is located until an emergency happens.

At Rossman Plumbing, we often receive calls from homeowners dealing with burst pipes, leaking water heaters, overflowing fixtures, and other plumbing emergencies. In many cases, knowing how to quickly shut off the water can significantly reduce damage and save thousands of dollars in repairs.

When Should You Shut Off Your Water?

There are several situations where turning off your home's water supply is a smart decision.

Plumbing Emergencies

If a pipe bursts, a water heater begins leaking, a supply line breaks, or a fixture starts overflowing, every second counts.

Before Going on Vacation

Many homeowners leave for days or even weeks without considering their plumbing system.

During Freezing Weather

While Southern California doesn't experience freezing temperatures often, cold weather can still affect exposed pipes in some areas.

During Major Plumbing Repairs

Any significant plumbing repair may require shutting off the home's water supply. Knowing how to do this can save time and help avoid unnecessary flooding when performing minor repairs or maintenance.

Where Is the Main Water Shut-Off Valve Located?

The location varies from property to property, but common locations include:

How to Shut Off Your Water

Most residential shut-off valves are either:

Gate Valves

These valves use a round handle that must be turned clockwise until fully closed.

Ball Valves

These valves use a lever handle. To shut off the water, turn the handle one-quarter turn until it is perpendicular to the pipe.

Once the valve is closed, open a faucet inside the home to confirm that the water supply has been shut off.

Don't Forget Your Water Heater

If you shut off the main water supply for an extended period, it's also a good idea to consult your water heater manufacturer's recommendations regarding operation during prolonged absences.

Consider Upgrading Your Shut-Off Valve

Many older homes still have aging shut-off valves that can become difficult to operate or fail when needed most.
