Floor Drain Systems

Plumbing systems usually function for years without needing attention, and like many basic utilities they are often forgotten until a problem arises. This fact sheet outlines tips for preventing plumbing problems. Basic information about floor drain systems and separators—devices used to isolate and collect flammable and oily waste from wastewater before it enters the sewer system—and simple maintenance ideas are covered.

To help minimize and prevent separator troubles, periodic inspection and maintenance are necessary. Finding the separator access may be a challenge in renovated or remodeled buildings. Long neglected separator maintenance problems may require hiring a clean-out service and arranging for proper disposal of the sludge. Use the following prevention tips to reduce or eliminate drain maintenance and save money. Solvents, cleaners and other industrial liquids lost to the floor drain cost money to replace, clean out of separators and dispose of waste properly.

Capping and Plugs

Determine if all the floor drains are needed. Cap unnecessary floor drains. If a drain location could cause or contribute to problems with separators consult a licensed plumber to cap the drain . Minnesota Department of Health codes recommend drains be capped by a licensed plumber. If improperly capped, abandoned drains can be a dangerous source of accumulated sewer gases. Temporary sewer plugs may be used in emergencies to help contain spills and prevent discharge to the sewer, but they are not a permanent fix.

Be prepared for spill emergencies. Keep all industrial liquids and activities using these liquids away from floor drains. Sludge that accumulates in separators may become hazardous waste if you are careless about the contaminants that mix with dirt in the floor drain .
