Clogged Sewers: Causes and Solutions

Sewer lines are an essential part of any drainage system, as they transport waste and wastewater from homes and buildings to treatment facilities. However, clogs can occur due to a variety of reasons, leading to backups, foul odors, and health hazards. In this article, we’ll explore the causes of clogged sewers and some solutions to this problem.

Causes of Clogged Sewers

There are several reasons why sewer lines can become clogged. Some of the most common causes are:

1. Tree Roots: Tree roots can grow into sewer lines, causing them to crack and block. This is especially common in older homes with clay or cast iron pipes.

2. Grease and Oil: Pouring grease and oil down the drain can solidify and stick to the walls of the sewer line, leading to blockages.

3. Foreign Objects: Flushing non-biodegradable materials such as wipes, diapers, and feminine hygiene products can also cause clogs.

4. Debris: Large debris such as leaves, twigs, and rocks can also cause sewer backups, especially during heavy rainfall.

Solutions to Clogged Sewers

If you suspect that your sewer line is clogged, it’s important to act quickly to prevent further damage. Here are some solutions to this problem:

1. Professional Inspection: Hiring a professional plumbing company such as Blue Sky Plumbing to inspect and clean your sewer lines every year can prevent clogs from forming in the first place.

2. Hydro Jetting: This is a high-pressure water jetting process that can clear out any clogs and debris in your sewer line.

3. Removal of Tree Roots: If tree roots are causing the blockage, a professional plumber can remove them by cutting or treating them with chemicals.

4. Routine Maintenance: Preventive maintenance is key to avoiding clogs in your sewer line. This includes disposing of grease and oil properly, avoiding flushing non-biodegradable materials, and cleaning out debris from gutters and downspouts.


Clogged sewers can cause a lot of inconvenience and health hazards if left unchecked. To avoid this problem, it’s important to be mindful of what is flushed down the drain, and to schedule regular inspections and maintenance with a trusted plumbing company. With the right measures in place, your sewer lines can function seamlessly for years to come.

Pete and Noah came to my building and intalled a new hot water tank within a few hours so that my tenant had hot water again. Very professional and efficient service. Thank you.

I just wanted to take the time to say Kyle Hall with plumbing is a phenomenal business owner who works skillfully to take care of your plumbing needs. I have seen him referred to many jobs and even when there is something not necessarily needed he will take the time to point that out, that's a great ethical business practice. He can also do Leak detection. He is literally running the business single handed (after an injury) and still managing to create happiness from his services. Great job Kyle and plumbing team. Higly recommended !!! ***** From me.

Had a whole house sewer re-pipe done and the crew was outstanding. Very professional and respectful, wore booties inside and always kept us informed regarding our ability to use restrooms, water, etc. It was 100+ degrees the days they were working and to be honest I was worried about them but they stayed on schedule while working safely and effectively. High marks to all involved!
