How to Find a Buried Sewer Cleanout

A sewer cleanout is an essential part of your home’s plumbing system since it is how your main sewage line is accessed. A sewage cleanout usually consists of a pipe with a removable threaded cap. It’s important to know where your sewer cleanout is located since not all sewage access pipes are buried. The cleanout will need to be accessed by a plumber in the event of an emergency or blockage.

Where Is the Sewer Cleanout?

The location of your cleanout depends on the size of your home and your local climate. If you live in a colder area, your cleanout is most likely located inside your house near a bathroom, utility room or garage. Homes built on a slab foundation also sometimes have an outdoor cleanout.

How to Find an Outdoor Sewer Cleanout Valve

If you do have an exterior sewer cleanout, it’s usually easy to find. Here are some simple tips to help you find it:

  1. Walk around the perimeter of your house and look at the area close to the foundation.
  2. A sewer cleanout is generally, but not always located outside a bathroom. You’ll recognize it as a black or white, three- to four-inch capped pipe.
  3. Since cleanouts aren’t needed often, yours may be covered by bushes, underbrush or grass.
  4. Alternatively, it may be concealed in a box close to the ground with a metal cover, so keep your eye out for anything that may contain a large pipe.
