Without the strainer or grate cover, a floor drain will just look like a big hole in the floor. Besides preventing large pieces of debris, or hard physical objects from entering the drain, the strainer also prevents physical injury. The cover can also stop unwanted pests, such as rodents. A strainer with a small grating can act as a barrier for a lot of small objects including gravel, but it will restrict the flow of water and make it drain slowly. Bigger grating openings allow for drains to operate more quickly. But larger grating openings require more maintenance to clean debris from the trap, or the drain sump. A sump full of debris will lead to a floor drain backup.
