How to Find the Main Water Shut Off Valve in Your Home

Hopefully the water you have coming into your home, and the systems installed to provide this, work properly and you don’t have to think much of them. Normally, the main water flow system doesn’t require much maintenance. However, when something does go wrong, it happens very quickly and causes a big mess. The first thing that should be done when this happens is to locate your main water shut off valve and get the water to stop as soon as possible to prevent secondary damages.

Why Should I Know How to Shut Off the Water in My House?

  • A broken pipe can cause mass chaos in your home. If you notice damp drywall in your home, immediately find the main water shut off valve to deactivate your water supply. This pipe may have frozen, cracked and then thawed out or it could be an old pipe needing to be replaced.
  • A faucet that has sprung a leak and needs to be repaired.
  • A broken and leaking water heater – a pool of water around the base of the heater will be an indication.
  • Any leaking pipe, whether it is in the walls, evidenced by wet spots on the drywall and along the baseboards of any room next to a wall that has pipes in it.
  • A frozen outside water bib that has thawed out and is now leaking.
  • Any do it yourself projects that involve water fixtures. Accessing the main water shut off valve is appropriate to ensure nothing is damaged by any water that may leak or spurt out while working on that fixture.
  • A leaking or broken water pipe under the slab of the house. This often hard to notice and can be evidenced by detecting a soft spot under the floor or a musty, earthy smell.

All of the above issues need immediate attention by you turning the water off before any real damage can happen and while you are calling the plumber or gathering your tools.

How Do I find the Main Water Shut Off Valve?

Appliance Water Shut Off Valve

There are two categories of water shut off valves that you should be familiar with that can be utilized to shut off the water in your house. One type will be under the sinks, around the toilet tank and by the water heater. These control the water feed to the faucets, toilet water tank or the water heater and not to anything else. If these items need the servicing, you can stop there by turning the handle to the right, shutting the water to the fixture off, taking care of the problem and turning it back on after everything is tight.

Main Water Shut Off Valve

The second type of valve is called the main water shut off valve and can be found in the garage, utility room or storage area of your home. It might be behind an interior wall, behind an access panel or door. A look at your home inspection document may help you locate the main water shut off valve in your home.

  • The first thing to identify is where your water meter is. If you trace the location of that meter to your home, in a straight line, the place to look for the main water shut off valve will be right there on the interior of that wall.
  • If you’re trying to find a main water shut off valve in a home with a basement, you want to look at the perimeter of the house at or above eye level. The main water supply comes in about one to two feet below the surface of the ground. A pipe, hopefully with a handle, will be the main water shut off valve.
  • If there is no basement, it the water shut off valve may be in the garage, utility room or storage area. It might be behind an interior wall, hopefully, accessible through a panel or door. A look at your home inspection document may give you some guidance. A call to a local plumbing service company can also help you.

The Main Water Meter

This is usually out front because that is where the municipal water comes from. It should be fairly easy to find as the water company must locate it each month or two to read the meter. If you pull the cover off and look inside, you will see the meter and one or two valve handles. If there are two, each one is on separate sides of the meter.

  • The one on the street side will be the one the water company uses to shut the water off when you have not paid your bill. It utilizes a tool you do not have access to.
  • The main water shut off valve in your house takes a tool you can purchase from a plumbing supply or home improvement store.
  • In an emergency you can use an adjustable jaw (crescent) wrench and a screwdriver to turn the handle of the main water shut off valve to the right to shut off all water from reaching your house.
