Unfortunately, plumbing issues are almost inevitable, especially if you have an older home. For this reason, it is crucial to locate the sewer line. There are benefits to knowing where your sewer line is. Knowing the ins and outs of your home sewer system allows you to quickly tend to any emergency plumbing situation like clogs or buildups. Another benefit of knowing where your main sewer line is located is that it allows you to inform the plumber of its location leading to a smoother — and possibly less expensive — appointment. If you’re not sure where your main sewer line is, we’ve got you covered! Check out our tips for locating this critical part of your home sewer system

Know What Type of Pipe You’re Looking For 

Your main sewer line piping is going to look distinctly different from other pipes. This section of plumbing will likely be four inches in diameter, and the beginning of the line will have a screw top. The capped part of the main sewer line may also be called a cleanout, and it’s typically white in color (it could also be badge or gray due to color fading). 

Know Where to Look

Have you ever wondered how deep your sewer lines are? Understanding this can help you have a clearer idea of the location of the main sewer line. Since sewer lines are underground, you may likely want to start your search in your garage, basement, or crawl space if you have one. Also, some sewer line cleanouts are located outside, so you may want to extend your search to your backyard. The line could also be near your main floor bathroom, so check the side of your home where this plumbing might be, and clear away any debris that could be blocking your view. 

Get a Residential Plumbing Diagram from the County Clerk 

If you’re still not sure about where the main sewer line is located in your home, we recommend calling the county clerk for some extra help. This local government professional typically has access to your neighborhood’s plumbing diagram and can send it your way to help you find the main sewer line. You may also want to ask them to look for a sewer house trap diagram, as this document can also help you find the main sewer line. 

Knowing where your main sewer line is can help you quickly locate sewer line problems and provide the necessary information to a plumber that you need to solve any plumbing complications efficiently.
