"Needed baseline data on sewer laterals, rain drains, storm drains and courtyard drains, as well as some drain cleaning in a townhome complex. Service was prompt, communication good, everyone courteous. Received a detailed description of work done and findings at each unit for a very reasonable price."

"I have to say this company impressed me every step of the way. From the first time I called until the job was completed, they we're punctual professional and I waited for nothing. I usually expect to wait for return calls, emails etc. I was always supported when my inquiries were answered within minutes. Everything was seamless. I've had many experiences with terrible customer service and expensive repairs left not feeling like I got my money's worth. Not with Simpson Plumbing. They come highly recommend by me."

Sewer Cleaning FAQs, answered by experts

Even with a high-resolution camera, what you're looking at on the screen may not be recognizable to the untrained eye. Your plumber should be willing to walk you through the video and explain what they found. With high-res images, bright lighting, and self-leveling technology, you should get clear, steady views of the pipes that make up your plumbing system.

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.
