Things You Should Know About Floor Drains and Floor Sinks

A floor drain is a plumbing fixture that is installed on the floor of a structure, mainly designed to remove any standing water near it. They are usually round, but can also be square or rectangular. They usually range from 2 to 12 inches; most are 4 inches in diameter.

How can you describe the difference between a floor drain and a floor sink?

Floor sinks are usually used where equipment drains require an air gap, like commercial restaurant appliances. They actually have some storage capacity, and usually have a drain screen and removable grate for servicing the fixture. Floor sinks are also larger than most floor drains, 12 inches by 12 inches, where drains are usually 4 or 6 inches in diameter. Floor drains in laundry rooms, mechanical rooms, and bathrooms generally allow the whole floor to drain into them if the floor is sloped correctly, where a floor sink is usually flat and flush with the adjoining floors. Above is a floor sink I installed in a food court remodel project this year.

What is the difference between the floor drain and the floor trap?

The 'sewer' side will have sewer gases present, but the water sitting in the bottom of the trap prevents the sewer gases from entering into the house. Floor drains are no exception. The shaded portion shows the trap where water will always sit, which prevents sewer gas from coming in

What are floor drains connected to?

A common floor drain system includes a concrete trench that runs down the center of the shop floor. The trench is designed to capture water, cleaners, oil, dirt, or other materials. Some shops have small, rectangular, or round floor drains connected to underground piping.
