Whether you’re addressing a plumbing repair, tackling water damage prevention, or preparing your home for a vacation, knowing how to turn off the water to your house is an essential skill every homeowner should have. Water leaks can cause significant damage in a short amount of time, so it’s crucial to act quickly when you need to. Fortunately, shutting off the water supply isn’t as complicated as it sounds. We’re here to guide you through every step with detailed, yet simple, instructions.

If you’ve been Googling “turn off water to house” searching for answers, we’ve got you covered. By the end of this step-by-step guide, you’ll feel confident in your ability to locate and shut off your water supply when the need arises.

Why Should You Know How to Turn Off the Water to Your House?

Having quick access to your home’s water shut-off valve can prevent costly and extensive damage. Here are a few situations where turning off your water supply is essential:

  • Burst Pipes: A burst pipe can release gallons of water in a matter of minutes, causing extensive water damage throughout your home.
  • Plumbing Repairs: Many plumbing fixes require you to shut off your water temporarily to ensure safety.
  • Water Heater Issues: If your water heater is malfunctioning or leaking, cutting off the water supply is the first step.
  • Leaving for Vacation: Prevent potential water damage from leaks or unexpected issues by turning off the water before a trip.
  • Emergency Situations: Flood warnings, severe storms, or supply issues can sometimes call for you to turn off the water to your home.

Now that you know why it’s important, let’s walk through how you can locate and turn off your water supply.

Tools You Might Need

Before we get started, ensure you have the following items on hand to make the task easier:

  • A flashlight or headlamp to see in dark areas
  • An adjustable wrench (if your shut-off valve is a bit stiff)
  • Towels or rags in case there’s any residual water

These tools are optional but helpful depending on your setup.

Turning off the water supply to your house might sound daunting, but it’s a straightforward process when you know what to do. Whether you’re dealing with a plumbing emergency or performing routine maintenance, this guide will walk you through the steps to ensure everything is done safely and efficiently.

1. Locate Your Main Water Shut-Off Valve

The main water shut-off valve controls the flow of water entering your home from the city water line or your private well. The valve is often located in one of a few places:

  • Basement or Crawl Space: Check along the perimeter walls of your basement or crawl space. The valve is usually positioned where the water line enters your home.
  • Garage: If your water meter is located outside, the shut-off valve may be inside your garage.
  • Utility Room: If your home doesn’t have a basement or garage, utility rooms or closets may house the shut-off valve.
  • Outside (Near Water Meter): For homes in warmer climates, the valve may be located outside your house where the main water line connects to your home.

If you’re struggling to find the valve, try tracing the water line backward from your water heater or outside meter.

Pro Tip: Label the shut-off valve clearly so everyone in your household can locate it in an emergency.

2. Identify the Type of Shut-Off Valve

Once you’ve found your shut-off valve, determine the type you have. There are usually two types of shut-off valves used in residential plumbing:

  • Gate Valves: These have a round handle that you turn multiple times to open or close. Turn the handle clockwise (right) until it stops to shut off the water.
  • Ball Valves: These valves have a lever handle. Simply turn the lever 90 degrees so that it’s perpendicular to the pipe to shut off the water.

Ball valves tend to be easier and quicker to operate compared to gate valves.

3. Shut Off the Water Supply

Now it’s time to shut off the water supply completely:

  • If you have a gate valve, turn the handle clockwise as far as it will go.
  • If you have a ball valve, rotate the lever so it is perpendicular to the pipe.

Once done, open a faucet (preferably one on a lower level of your house) to confirm that the water supply is fully turned off. If no water flows, you’ve successfully shut off your water supply!

4. When Your Shut-Off Valve Doesn’t Work

Over time, shut-off valves can become stuck or corroded, particularly if they haven’t been used in a while. If your valve doesn’t seem to work:

  • Use an Adjustable Wrench: Carefully apply force to loosen a stuck shut-off valve.
  • Call a Professional: Contact a licensed plumber to replace or repair the valve if it remains unresponsive.

Remember, a stuck valve can lead to wasted time in an emergency, so it’s best to address the issue as soon as possible.

5. Shutting Off Water for Individual Fixtures

Sometimes, you don’t need to turn off the water to the entire house. For smaller fixes, you can use the localized shut-off valves for individual fixtures like sinks, toilets, or appliances.

  • For Sinks: Look under the sink for small shut-off valves. Turn these clockwise to shut off.
  • For Toilets: The shut-off valve is usually located behind the toilet near the wall.
  • For Washing Machines or Dishwashers: These appliances typically have dedicated shut-off valves located on the wall behind them.

Knowing how to access these valves can save time and effort for minor plumbing work.

Preventative Maintenance Tips

A hand is turning a blue valve on a copper pipe against a concrete wall. Two pipes run parallel to each other, one copper and one gray. The valve is shaped like a gear. The wall is rough with visible lines and cracks.

To ensure you’re always prepared to turn off the water to your house, follow these maintenance tips:

  • Check Your Shut-Off Valve Regularly: Test your main valve every six months to ensure it opens and closes smoothly.
  • Label Valves: Clearly label your main and individual shut-off valves for easy identification.
  • Keep the Area Clear: Avoid clutter near your shut-off valve so you can access it quickly in emergencies.
  • Replace Old Valves: If your shut-off valve is rusted, corroded, or leaking, have it replaced promptly by a professional.

When to Call a Professional

While turning off water to your house is usually straightforward, there are instances where a plumbing professional may be necessary:

  • If you cannot locate your shut-off valve.
  • If the valve is rusted, broken, or won’t fully close.
  • To replace your shut-off valve with a more reliable or accessible option.
  • Or if you smell gas near your water meter or shut-off valve, which could indicate a gas leak.

Plumbing emergencies can be stressful, and having a reliable expert on hand can make all the difference.

After months of high water bills and feeling itchy, the Aquarius team came to the rescue. My 25 year old kinetico softener finally gave up and was constantly cycling. At the end of the service call we realized the old unit wasn't worth repairing. They sent out a salesperson the same day, providing a great range of options to fit my price point. My new softener arrived early so we were able to move up the install date. Install was flawless and we're back to having the softest water ever. I'm super happy with every interaction I've had with the Aquarius team. They are all super friendly, knowledgeable, and professional. I rarely leave reviews and only leave them when I'm really impressed. That's definitely the case with this company.

First, Aquarius responded to my interest in an RO system promptly. After deciding to commit to their solution, the installation, Including a water softner solution, it was scheduled the same week. Michael was the installer and he called when in transit and arrived right on schedule. We went over the work to be done and the placement of the equipment with only one issue that arose. The RO and water softener installation would not be a problem, but plumbing for the outdoor outlets would require additional material and labor, not included in the quote. I was looking forward to using the outdoor faucets without switching the system over. We elected to continue with the installation and Michael kept us informed throughout the day of his progress and completion time. He had everything cleaned up and provided us with a review of the system. To date, we are very pleased with the system and want to thank Michael for a great install. My only recommendation to Aquarius would be to take an additional step, during the initial meeting possibly, and physically look at the plumbing to ensure the quote covers all the materials to meet the customer request.

We have had our Aquarius services longer than a decade. During this time, the equipment has never failed us, but more importantly we have received absolutely outstanding customer service anytime we have needed anything. Today was no different, Wyatt came to our house to do our periodic inspection and was able to help troubleshoot a problem and find a solution the very same day. The entire time he was here, he kept his workspace, clean and orderly, and he was very polite and respectful of our home. The shocker came when he was about to leave and told me this was his fifth day On his own! Very impressed, not only with him as a person, but the quality of employees that come out out of Aquarius. Highly recommend this company.

I had an old furnace that was on its last legs and needed to be replaced ASAP.Day one: Service Tech arrived 2 hours after initial contact with Aquarius. Sales Rep arrived within an hour of the request. Deal was made and installation appointment scheduled for the NEXT DAY!Day two: Contacted by the installation team at 7:00 am. Arrived at 7:30. Finished up by 2:30.All of the staff that I dealt with were friendly, professional and great to work with. They explained everything very well. I was expecting to wait 2-3 weeks for a new furnace and A/C. This was all done inside of two days. I would 100% recommend Aquarius to anyone needing any type of home service.Tall Mike, Mike Sippel, Chris Oigard, Dave and Luke it was great to work with you. Thanks for everything!Oh, they like dogs too.
