A sewer cleanout is a capped opening on a building’s drain or sewer line that gives a plumber access to the pipe. It lets the line be cleared or checked without removing a toilet or opening a wall or floor.
Many property owners never notice their cleanout until there is a backup. Knowing what it is and where it may be can save time when a sewer line needs cleaning.
What a Cleanout Looks Like
A cleanout is usually a short section of pipe with a screw-on or plug-style cap. It may stick up from a basement floor, sit on the side of a pipe along a wall, or be set in the ground outside with a cover over it.
Some buildings have more than one. Some older New York City buildings have a fitting called a house trap near where the sewer line leaves the building, often with two caps on top that serve as access points. Every property is different, so the setup at yours may not match these examples.
Why a Cleanout Matters for Sewer Cleaning
When a main line slows down or backs up, the plumber needs a way to reach the blockage. A cleanout close to the problem can make that easier and may limit mess inside the home.
If there is no clear access point, the plumber may need to work from a fixture, such as a toilet, or look at other options. That can affect how long the job takes and what it involves. In some cases, adding a cleanout may be something to talk about for the future.
Why You Should Not Open It Yourself
It may be tempting to remove a cleanout cap during a backup, but this can be risky. If the line is full, wastewater can rush out with force as soon as the cap loosens. That can flood the area and expose you to sewage.
Old caps can also be stuck, cracked or hard to reseal. A cap that is damaged or not put back tightly may let sewer odors or water escape later. Leave opening and closing the cleanout to a plumber.
Helpful Things You Can Do
You can still help in safe ways. If you know where the cleanout is, keep the area clear of boxes and stored items. In a basement, make sure the plumber can reach it easily. Let the plumber know if you have seen water or odors coming from the cap.
In Bronx apartment and mixed-use buildings, the cleanout is often in a basement or utility area that only staff can enter. Owners and supers should know where it is and keep it accessible.
