Dealing with a Backed-Up Sewer Line: Causes, Prevention, and Solutions

A backed-up sewer line is a frustrating problem that can cause significant damage to your property and potentially lead to health hazards. It occurs when waste materials cannot flow away from your home and instead backs up into your drains and fixtures, causing nasty odors, unsanitary conditions, and even structural damage.

Dealing with a Backed-Up Sewer Line: Causes, Prevention, and Solutions

In this article, we will discuss the causes of backed-up sewer lines, how you can prevent them from happening, and solutions for dealing with them if they occur.

What Causes Backed-Up Sewer Lines?

Several factors can lead to a backed-up sewer line. Here are some of the most common:

Tree Roots

Tree roots seek out sources of water in the soil, which sometimes leads them to grow towards sewer pipes. Over time, these roots can penetrate through small cracks or joints in the pipe wall and create blockages.


Clogs are a common cause of backed-up sewer lines. They can result from flushing improper items down the toilet (such as wipes or feminine hygiene products), putting food scraps down the kitchen sink or garbage disposal without proper grinding, or pouring grease down any drain.

Aging Pipes

Over time, pipes wear out due to natural deterioration or corrosion. Older homes may have pipes made of materials that are no longer used today like cast iron which is known for rusting therefore reducing the diameter of its bore from inside which eventually causes clogging of waste pipeline created afterwards.

How to Prevent Backed-Up Sewer Lines?

Preventing backed-up sewer lines is easier than dealing with them once they occur. Here are some preventive measures you should take:

Avoid Flushing Non-Biodegradable Items

Toilet paper should be the only thing you flush down your toilet. Anything else could cause clogs and ultimately lead to a backed-up sewer line.

Avoid flushing non-biodegradable items, feminine hygiene products, and wet wipes down the toilet. Dispose of them in a trash can or specially designated container for such waste.

Dispose of Kitchen Waste Properly

Avoid pouring grease, fat, and oils down the kitchen sink or garbage disposal. These materials can harden and form blockages that could lead to backed-up sewer lines.

Instead, dispose of them in a container and throw them away in your regular garbage.

Do Not Plant Trees Near Sewer Pipes

If you are planting trees near the sewer pipes, make sure they are at least ten feet away. This distance ensures that their roots cannot reach the pipes and cause blockages.

Regular Maintenance

Regular maintenance of your plumbing system is crucial to preventing backed-up sewer lines. Hire a professional plumber to inspect your plumbing system annually and clean any clogs as soon as they arise.

Solutions for Dealing with Backed-Up Sewer Lines

If you do encounter a backed-up sewer line issue despite all preventive measures, here are some solutions:

Call a Professional Plumber

The first step in dealing with backed-up sewer lines should be calling a professional plumber. They will have specialized equipment that can diagnose the problem quickly and accurately.

They can also address any more long-term solutions like installing new pipes or relining existing ones which will also prevent further blockages from occurring.

Use Chemical Drain Cleaners (with Caution)

Chemical drain cleaners can break up clogs blocking your pipes but be careful because these chemicals may harm PVC pipeline material commonly used today for waste water management so it’s better to check before using them.

Follow all instructions carefully when using chemical cleaners, wear gloves & mask for safety purposes while handling these chemicals as they contain corrosive elements which may irritate skin or respiratory tract if misused or not handled cautiously.

Hydro Jetting

Hydro jetting is an effective way to remove stubborn blockages from your pipes. This process uses high pressure water to break up clogs and flush them out.

Hydro jetting services are offered by many professional plumbers, and they can be a highly effective solution for dealing with backed-up sewer lines.

Digging Out the Clog

In some cases, digging out the clog manually may be necessary. If the blockage is severe and traditional methods have not helped, excavation can provide access to the blockage point and it can then be removed easily but it will require significant efforts & resources especially if sewer lines are deep underground.


A backed-up sewer line is an unpleasant issue that nobody wants to deal with, but it’s something that homeowners must prepare for. Proper preventive measures like avoiding flushing non-biodegradable items down the toilet or disposing of kitchen waste properly, regular plumbing maintenance can help avoid this problem from occurring.

If you do end up facing a backed-up sewer line, calling on professional plumbers who have specialized equipment, experience & expertise in removing stubborn blockages from pipes using modern methods like hydro jetting should be your top priority. Remember that quick action can prevent further damage to your home and costly repairs in the long run.
