How to Shut Off Your Water Main (Every NJ Homeowner Should Know)

On Call NJ · Plumbing, Heating & Cooling Experts

When a pipe bursts or a fixture floods, every second counts. Knowing where your main water shut-off valve is, and how to use it, can be the difference between a quick cleanup and thousands in damage. Take five minutes today so you're ready.

Where to find the valve

In most New Jersey homes, the main shut-off is located where the water line enters the house, often in the basement, a utility closet, or near the water heater. It may also be outside near the foundation or at the street in a covered box.

Types of valves

  • Gate valve: a round wheel you turn clockwise several times to close
  • Ball valve: a lever you turn a quarter turn until it's perpendicular to the pipe

Test it now, not in a crisis

Valves that haven't been turned in years can seize. Locate yours today and gently confirm it turns. If it's stuck or leaking, have it serviced before you actually need it.

If your shut-off valve is corroded, stuck, or leaking, don't force it. Call 862-860-1807 and we'll replace it so you're protected.

After you shut it off

Once the water is off, open the lowest faucet in the house to drain remaining water from the lines, then call a licensed plumber to handle the repair.
