To get rid of that unpleasant basement floor drain smell, begin by clearing away any visible debris and wiping down the drain cover. Also, add water to the drain to refill its trap. This acts as a barrier against sewer gases from coming back up. If the odour persists even after you have cleaned it, you might be dealing with a clog, a cracked pipe, or some other plumbing issue that gets resolved by a professional plumber. Below, I have shared how to clean a smelly basement floor drain.
How can You Remove Bad Smells from a Basement Floor Drain?
Lift the cover gently if it is designed to detach without difficulty. Don't try to open it forcefully.
Wear rubber gloves and remove any noticeable hair, leaves, and other unwanted materials from around the drain opening.
Take care to clean the cover properly. Wash it using warm water and a mild dish soap, then use a soft brush to remove any stubborn buildup.
Pour a bucket of fresh water slowly into the drain trap to restore the water level. This water layer serves as a protective barrier that blocks sewer gases from entering your basement.
If a dry trap was responsible for the smell, refilling it with water might solve your problem. That said, if the smell continues even after cleaning, you may need additional measures to fully address it.
Don't ever mix bleach, acids, or multiple drain-cleaning chemicals, as this can be dangerous. If you notice sewage backing up, stop attempting to clean the drain yourself any further. Pour water into floor drains that don't get much use about once a month. This helps keep the trap from drying out. If the unpleasant smell returns quickly, you notice poor drainage, or you hear gurgling sounds, call a plumber.
