Possible Reasons for Water Coming Up from Basement Drain

In this chapter, we only focus on the issues that are responsible for your basement drain flooding.

Faulty City Sewer System

As we mentioned earlier, a problem with the city sewer system is the number one reason for water coming up through the floor. As most homes in your neighborhood are connected with the city sewer system, it puts a lot of pressure.

In other words, the city sewer could be absolutely overcapacity and not letting water out—consequently, water flooding and backing up into your house.

Problem with your overloading sewer system

When we are crying out about the problem of the city sewer system, we forget about the sewer system in our house. Your old overwhelming sewer system may not be designed to handle the amount of runoff after heavy rain.

Therefore, if your sewer system gets blocked, the sewer water backs up through the sink or floor in your basement. Generally, the sewer pipe is blocked by debris, dirt, and tree roots.

Solutions

You know what makes the sewer water backups. Now, it’s time to get your hand to solve the issues.

Call Municipality for Help

If you discover a problem with the city sewer system, don’t hesitate to call your local municipality. It’s a nationwide problem in your neighborhood, and sewer water backs up due to the older city sewer pipe.

Fix your own sewer system

Once you figure out the problem is with your sewer system, repair it to overcome the issue.

If the sewer pipe gets broken or clogged, fix it and release the block. You can hire a professional plumber, in this case, to do it for you. Plus, installing rubber plugs on the drain can also solve the sewer water problem right off the bat. However, it’s a temporary solution.

For a permanent solution, you can install a backflow preventer. It’s basically a one-way valve that lets the wastewater leave your home but does not allow the runoff to come back through the pipes.

Get a Sump Pump

Using a sump pump is a DIY method to flow the sewage water out from the basement. Though the sump pump makes a weird sound, it is helpful to tackle sewer water. Make sure the pump you get is powerful enough to handle the amount of water that comes in your basement.

Therefore, ensure there is space or sink nearby as the sump pump redirects water to another place.
