Where Can I Find the Water Shut Off Valve?

The location of your main water shut-off valve can vary based on the design of your building and local building codes. However, there are a couple of common places you might want to check:

In Homes

Typically, you’ll find the main water shut-off valve in the basement, crawlspace, or on an exterior wall in a utility area of the house. This is because the valve is generally located where the main water line enters your home from the street. 

If your house is on a slab (like many in the Vancouver WA due to our damp weather), check near your water heater or under your kitchen sink. It might also be housed in a box buried near the street — look for a metal cover flush with the ground. In some neighborhoods, the shut-off valve might be in the front or back yards.

In Businesses

For commercial properties, the shut-off valve might be in a utility closet, basement, or maintenance room where water lines emerge from the ground.

Water Main Shut-Off Valve Types

There are several types of water shut-off valves, but these two are the only ones used for main shut off valve, for the main water system:

Ball Valves: These are more common these days. They have a lever handle and are easier to turn off in a hurry. Just swing the handle perpendicular to the pipe to shut off the water.

Gate Valves: These are more common in older industrial buildings. They can be a bit tough to turn if they haven’t been used in a while. 

Knowing what type of valve you have will allow you to operate it more effectively and with less panic when the need arises.

Is it Okay to Shut Off the Main Water Valve?

Absolutely! It’s more than okay, it’s recommended in certain situations. If you’re dealing with a burst pipe, a major leak, or if you’re going to be doing some plumbing work, shutting off the main water valve can prevent water damage until help arrives or until the issue is resolved. 

It’s a smart move that could save you from extensive damage and expensive repairs. Shutting off the water is also a good practice when you’re leaving town for a while. No one wants to come home to a house that’s been sitting in water due to a plumbing mishap!

Why Can’t I Find My Main Water Shut Off Valve?

If you’ve looked in all the usual places and still can’t find your valve, there might be a few reasons:

  • Overgrown Landscaping: If the valve is outside, it might be hidden under overgrown bushes or covered by debris or soil.
  • Poor Marking: Sometimes, valves aren’t where you expect them to be, and they can be poorly marked.
  • Unconventional Home Layout: Some homes, especially older or custom-built ones, might have unique plumbing systems.

In these cases, don’t hesitate to call a plumber or your local water utility for help. At BCC Restoration, it’s our job to know these things, and we’re usually more than happy to help!
