Basement Drain Backing Up: Common Causes and Solutions

basement drain backing up

Dealing with a basement drain backup can be a messy and unpleasant experience for any homeowner. The problem can be caused by a number of factors, and it’s important to identify the root cause and take the necessary steps to fix it before it leads to serious water damage. In this article, we will discuss the most common causes of basement drain backup, the signs to watch out for, and the steps you can take to prevent and fix the problem.

What Causes Basement Drain Backup?

Blockages in Drainage Pipes

One of the most common causes of basement drain backup is blockages in the drainage pipes. Over time, sediment and debris can build up inside the pipes, causing them to narrow or become completely obstructed. Bathroom products such as baby wipes, paper towels, and feminine hygiene products also contribute to clogs in the drain line. This results in water backing up in the basement drain and sewage overflowing onto the basement floor.

Tree Roots in Sewer Line

Another common cause of basement drain backup is tree roots. Trees planted near the house can cause roots to grow into the sewer line, causing blockages and ultimately leading to backups in the basement drain. If you notice this happening, it is best to call a professional plumber to remove the roots and prevent further damage to the plumbing system.

Main Sewer Line Clogs

If you experience basement drain backup along with backups in other plumbing fixtures in your home, the problem may be caused by a clog in the main sewer line. This is a serious issue that requires immediate attention from a qualified plumber to avoid extensive water damage.

Signs of Basement Drain Backup

Water Coming Up From Floor Drain

If you notice water coming up from the basement floor drain, this is a clear sign of basement drain backup. Water should only flow down the drain, and if it’s coming up, it means there is a blockage somewhere in the drainage system.

Gurgling Sound from Drain

If you hear gurgling sounds coming from the basement drain, this could indicate that there is a blockage or clog in the pipe. The gurgling sound is caused by air escaping through the water in the trap caused by the clog.

Slow Water Drainage in Fixtures

If water is draining slowly from sinks, showers or other plumbing fixtures in your home, it may be an indication of an underlying problem in the plumbing system. The slow drain could be caused by a blockage in the drain pipes, leading to water backup in the basement drain.

Preventative Measures to Avoid Basement Drain Backup

Regular Drain Cleaning

Regular drain cleaning can help prevent blockages in the drainage system and reduce the likelihood of basement drain backup. Homeowners can use a plunger or chemical drain cleaners to remove blockages, or hire a professional plumber to perform more thorough drain cleaning.

Proper Disposal of Household Waste

To avoid clogs in the drain line, it’s important to dispose of waste properly. Paper towels, baby wipes, and feminine hygiene products should not be flushed down the toilet, as they can cause blockages in the pipes. Dispose of these products in the garbage instead.

Installing Backwater Valve

Installing a backwater valve is an effective way to prevent basement drain backup. This valve prevents sewage from backing up into the basement drain by allowing it to flow out of the house through another drainage system. A professional plumber can install the backwater valve to ensure it is properly placed and sealed.

Steps to Take When Dealing with Basement Drain Backup

Shut Off Water Supply

The first step to take when dealing with basement drain backup is to shut off the water supply to prevent further water damage. This will stop any water flow and prevent sewage from entering the home.

Try to Clear Blockage with Plunger

If the blockage is minor, homeowners can try to clear it with a plunger. However, if the blockage is severe, it’s best to call a professional plumber to avoid causing further damage to the plumbing system.

Call a Professional Plumber

If the blockage is severe, or if you have tried to clear the blockage with a plunger and it’s not working, it’s best to call a professional plumber. A licensed plumber has the necessary equipment and expertise to identify the root cause of the problem and fix it efficiently.

How to Fix Basement Drain Backup?

Cleaning the Drain Pipes

The most common solution to basement drain backup is cleaning the drain pipes. A professional plumber can use a high-pressure water jet to remove any sediment or debris buildup inside the pipes, restoring the proper flow of water.

Replacing Damaged Pipes

If the backup is being caused by damaged pipes, the plumber may recommend replacing the pipes. This will involve accessing the damaged section of the pipe and installing a new one to restore the proper flow of water.

Installation of New Drain System

If the plumbing system is outdated and causing frequent backups, a professional plumber may recommend the installation of a new drainage system. This will involve excavating the old system and replacing it with a modern, efficient one to prevent future basement drain backup problems.

In conclusion, basement drain backup is a common problem that can cause serious water damage to your home if not addressed immediately. Understanding the causes, signs, and preventative measures can help homeowners address the problem early and avoid costly repairs. Remember to call a professional plumber if you experience severe or frequent basement drain backups, as they have the expertise to identify and fix the problem safely and efficiently.
