What Causes A Floor Drain To Clog?

Homeowners know that paying close attention to the drains in sinks and tubs is important when it comes to avoiding a plumbing disaster. Even if you are monitoring these drains closely, you may be overlooking several drains that are essential to the performance of your plumbing system. These are floor drains.

You can find floor drains in multiple locations within your home. Most basements are equipped with a floor drain, as are many garage areas. Floor drains can also be found in areas where flooding could be a risk, like the laundry room or near your water heater.

A clogged floor drain can indicate serious trouble. Take the time to learn what can cause a floor drain to clog so you can take action to correct this problem in your home.


The floor drain in your basement is the closest drain to your municipal waste pipes. Debris that finds its way into any of the other drains in your home can collect near the entrance to the waste pipe, creating a blockage that prevents the passage of water.

Wastewater will start to come back up through your floor drain as a result of the debris. You can try using a plunger to push the debris into the waste pipe, but you may find you need the help of a plumber to fully eliminate the blockage.


Your home's plumbing system is a series of pipes that are all interconnected. These pipes all lead to the main waste line or septic tank, where waste is processed. Blockages in the pipes that service the drains in your home's toilets can result in raw sewage leaking back up into your home through the floor drains.

You will need the help of an experienced plumber to snake the floor drain and remove any clogs that are preventing solid waste materials from moving through with ease.


Another reason your floor drain might appear to be clogged is crystallization within the pipes. Soap, urine, grease, oil, and other materials that pass through your pipes regularly leave a thin film of residue on the interior walls of drainage pipes.

Over time, this film hardens and begins to crystallize. The film will eventually become so thick that it restricts the flow of water and waste through your plumbing system, causing floor drains to appear clogged. A specialized cutting tool must be used by an experienced plumber to remove a crystallized film from your pipes. Contact a service, like West Sound Plumbing Service, for more help.
