When you have a sewage backup in your basement, it could have several different causes. The most common problem is that there is a problem with the main sewage drain line. When this happens, the sewage backs up into the basement because it’s the lowest point in the house, and those sewer drains are the easiest means of escape for the excess water.

It could also be caused by an individual clogged drain in the basement, which is likely the case if you are only getting back up in one drain.

What Causes a Sewage Backup?

Clogs, buildups in pipes from grease, or improperly flushed items, such as paper towels or single-use wipes, are common causes of sewage backup. Damage to the sewer lines can also cause a sewage backup because it prevents water from flowing correctly. A strong storm with heavy rain can also overwhelm the city sewer system with water and result in backups into people’s homes.

Aging Sewage Systems

You may not know this, but pipes are aging fast. This is because in the past they were made of cast iron and clay piping which doesn’t last very long. Aging sewage systems can break down and crack, causing a host of problems including backups that result in flooded basements. The increase in the number of homes connected to already aging sewer lines has also contributed greatly towards these rapid increases we’re seeing today.

Can Tree Roots in Sewer Lines Cause Sewage Backup?

Shrubs and trees seeking moisture can make their way into sewer line cracks, eventually damaging the pipe and causing sewage backup. One way to prevent tree roots from entering your waterworks is by installing new plastic pipes for any leaks or other problems.

Once you have the backup fixed and your sewer drain is unclogged, you’ll need to clean the affected area. Wearing protective equipment, remove residual water using a wet dry vacuum. If there isn’t too much standing water, you could also use old towels that you’re willing to throw away afterward or even paper towels. Make sure to remove as much sewage water as possible as this will help prevent mold.

After removing the water, Gather any solids with a broom or shovel and dispose of them, along with any unsalvageable items, in a thick garbage bag. Items like books and soft toys that came into contact with sewage should be thrown away.

Next, you’ll want to disinfect the area. Luckily, you should be able to use the cleaning products you already have in the house.

How to Stop Sewage Backup in the Future

After dealing with a sewage backup in your basement floor drains, such as toilet backing up into a basement drain, you’ll never want to have that experience again. Here are some steps you can take to prevent a recurrence:

Plastic Pipes

Install new plastic pipes. If the problem that caused the basement drain to clog in your basement was damaged pipes, installing new durable plastic pipes will solve the sewage backup issue and make it much less likely to happen again in the future. This is an expensive option, but a very effective investment to make on behalf of your safety and health.

Prevent basement Drain Clogs Before They Happen

Keep Drains Clog Free

A much more straightforward (and cheaper) solution to do is adjust your family’s behavior to avoid clogged drains altogether. Avoid flushing wet wipes (even ones that are labeled as flushable), paper towels, and feminine products down the toilet. Pour unused grease and oil, left over from cooking, into the garbage or in a disposable container rather than washing it down the kitchen sink drain.

You can search and check your city or municipality’s website for a safe disposal guide. Here is the guide from New York City  as an example.

Backwater valves are another way to help prevent future sewage backups. They are one-way valves that let sewage pass out the drain, and it will not return or back up into your home.

Sump Pump Maintenance

Make sure your sump pump doesn’t sit on debris, such as silt or gravel, which could ruin the motor if sucked up into the pump. Instead, place it on something such as steady flat brick. A filter fabric around the basin is a must to prevent debris from coming in.

Remove Illegal Plumbing Connections

Make sure there are no illegal plumbing connections to your city sewer line. This includes sump pumps, French drains and other flood control systems. This can cause debris to clog your sewer lines.


The first thing you should do is turn off the water supply to the main line. Next, remove all debris from the drain. Then, pour hot water down the drain until the clog is loosened. If the clog still won’t budge, call a professional.

If you have a clogged main drain, you should pour some vinegar or baking soda down the drain. Baking soda is a natural product that will help break up any clogs. In addition, you may also try pouring boiling water down the drain. Boiling water helps loosen any blockages inside the pipe. However, this method isn’t recommended for people who don’t know how to use plumbing tools safely.
