How to Fix a Clog in Your Garage Floor Drain

The garage is an impressive structure that can serve several different purposes. It can protect vehicles and other belongings from outside conditions. Or it can serve as an entertainment area, workout space, workshop, or hobby area. 

How to Fix a Clog in Your Garage Floor Drain

Being that it can serve so many functions, it’s a good idea to have a floor drain in your garage to collect and redirect any water or liquids that may leak or spill. Of course, dirt and debris also find their way into the garage floor drain, which can lead to a clog.

Most garage floor drain clogs can be resolved by eliminating the solid blockage. This can be easily done by removing the grate, retrieving debris, and flushing the drain with hot water. 

How to unclog a garage floor drain

Before we get into the steps, it’s important to point out that there are two main types of garage floor drains. The most common one is a round floor drain, which as the name implies, has a round hole in the concrete floor (about a foot in diameter) that’s covered by a grate. The second type is a trench drain with a long, rectangular opening in the floor to collect water. Trench floor drains are typically more expensive to install but are less likely to clog. 

If your floor garage becomes backed up or clogged, follow these steps to fix it.

  1. First, locate the drain (using the descriptions we provided earlier) in your garage. Remember that the concrete floor will slope toward the drain to divert water in that direction. 
  1. Take off the grate. You will either need to unscrew or pry off the metal grate that covers the drain. If the grate itself is covered in debris, that may be the cause of the clog in the first place. 
  1. Inspect the drain for a blockage. For this step, you’ll want a pair of gloves, a flashlight, and a small tool like a trowel or screwdriver. Look into the floor drain and see if there is debris in the pipe, such as leaves, pet hair, paper products, clumps of dirt, or any solid objects. Use your tool to remove as much (for lack of better words) gunk out of the drain.
  1. Flush the drain with hot water. Once you have removed as much debris as possible from the drain, pour hot (but not boiling) water to break up any remaining sediment and push it through the pipe. Important note: do not use chemical drain cleaners.
  1. Reattach the grate. Clean up the area and keep an eye if the drain is still clogged or gets backed up next time it collects water or liquids
