How Do I Know if My Sewer Line is Clogged?

Save Time, Call Prime!

As a homeowner, you come to expect that things will occasionally go wrong. For the most part, it’s usually minor stuff that’s more annoying than problematic—like a leaky faucet or clogged toilet. But there are times when those problems progress from minor to major, leaving homeowners frantic and frazzled.

Fortunately, in many cases, the signs and symptoms indicating a potentially significant problem is on the horizon are apparent before disaster really strikes. Today, we’ll talk about one of those situations—clogged sewer lines—and provide you with a few of the most prominent warning signs that your sewer line may be clogged.

More than one drain is backing up

Experiencing a drain backup in one fixture is unfortunate, but it’s likely an isolated incident. It’s when you start seeing drains backing up in multiple fixtures that we start to think a larger issue could be in play. If your toilets, tubs, showers, and sinks are backing up with water, a clog in the main sewer line could be the culprit. A good way to test for this is to use one fixture and see if a separate fixture encounters a problem. For example, flushing a toilet shouldn’t cause water to come up through the sink.

You hear gurgling

If you hear a gurgling or bubbling sound from your drains or toilets, it could be a telltale sign of an impending sewer backup. While some may believe that these noises are normal, they are not and typically occur because water cannot flow freely through a pipe.

Gurgling is actually an easy-to-detect early sign of a blockage. Paying attention to gurgling is one of the best chances for a homeowner to address an issue before they have sewage on their floor.

You have slow-running drains

Just because your drains aren’t backing up doesn’t mean you’re out of the woods when it comes to clogs in the sewer line. In fact, repeated slow-running drains are a common sign of a sewer line clog. This usually starts to occur in the drain nearest to the sewer line clog before expanding to other drains throughout the home.

If you find yourself constantly having to use a plunger, it may be time to look into the sewer line.

The yard gets flooded

While it’s true that April showers bring May flowers, everyone knows that the wettest month in Baltimore is September. So, if you notice your yard is flooded this spring—and it hasn’t rained lately—a clogged sewer line could be the cause. This typically occurs when tree roots bust through the line, causing not only a clog but a leak.

With nowhere to go but up, water (and waste) seeps through the soil and collects in the yard. Much like we mentioned with those interior drains, leaking water from the sewer line that collects in your yard is likely to give off a foul and unpleasant stench.

If your sewer line is clogged, you need a professional

The skilled professionals at Prime Plumbing are experts at quickly locating sewer line clogs and leaks and working diligently to correct them. These clogs can be caused by any number of factors, from the flushing of inappropriate items to coagulated grease or oil that was inadvertently dumped down the drain.

    I had an outstanding experience with Prime Plumbing. When my kitchen sink got clogged with grease, they responded promptly and sent their skilled technician, Will, without delay. From the moment he arrived, Will exuded professionalism and helpfulness, making the entire service call a breeze. I was particularly impressed with the extra steps Will took to ensure the cleanliness of my home. He thoughtfully wore boot covers to protect my floors, and he even laid down a blanket in his work area, leaving no room for mess or inconvenience. Throughout the repair process, Will took the time to explain every step to me in detail. His clear and patient explanations not only gave me insight into the work being done but also instilled confidence in the expertise of Prime Plumbing. As a cherry on top, Will provided me with valuable tips to prevent future sink clogs. His willingness to share preventive measures showcases Prime Plumbing's commitment to their customers' long-term satisfaction. I cannot recommend Prime Plumbing enough for their prompt response, the exceptional service provided by their technician, Will, and their dedication to maintaining a clean, transparent, and informative experience. They have earned my trust, and I will undoubtedly turn to them for any future plumbing needs. A truly reliable and customer-oriented company! Updated Review 6/10/26 for additional work. I originally called Prime Plumbing because I was experiencing low water pressure at my home. They came out promptly, diagnosed the issue, and got everything working properly again. During the visit, they also took the time to evaluate my water treatment setup and provided several options and quotes for improvements without any pressure or sales tactics. After reviewing the options, I decided to move forward with a new water softener, salt tank, UV filtration system, and pressure switch installation. Ron and Hayleigh handled the entire project, and I couldn’t be more impressed with their professionalism and workmanship. They were knowledgeable, courteous, and took the time to explain everything they were doing. The installation looks incredibly clean, organized, and professionally done. It’s obvious they take pride in their work and care about doing the job right. They arrived on time, worked efficiently, and left the area spotless when they were finished.
