WHERE IS MY SEWER LINE CLEANOUT LOCATED?

Sewer lines are critical pieces of plumbing infrastructure that help move water and waste away from your home. While the city takes care of the municipal sewer pipes, it's the homeowner's responsibility to maintain those sewer pipes that fall within his or her property lines.

If there's a low section in the pipe, water and waste can accumulate there and develop a clog over time. It's important to know where your sewer line cleanout access port is so you can quickly remove any obstructions within the sewer pipe and restore flow in the sewer system.

LOOK AT YOUR PLOT PLANS

One of the best ways to find the location of your sewer line cleanout access port is to look at the engineered plot plan for the home. Sewer service lines will be shown on these documents, and can lead you to the cleanout point.

These maps will be essential tools to help professionals avoid the lines when digging is required.

SEARCH IN LIKELY PLACES

If you don't have plot plans or can't identify the cleanout access on the map, start looking in the places where the sewer line cleanout is most likely to be. The cleanout is usually a 4-inch-diameter pipe with a screw cap that has a square knob or indentation on the top.

It's most likely going to be popping up from the ground outside your home between the foundation and the street. The cleanout might also be on the side of the home, closest to the bathroom.

Cleanout access ports might also be located in the basement or covered by drywall, but these aren't typical for most homes. If it's within the wall, you'll need to cut out parts of the drywall to look for it, but this can get messy quickly. Make sure to carefully avoid wires and other pipes.
