Why Does My Floor Drain Keeps Backing Up

When water backs up out of a floor drain, it usually means there is a clog in the drain line, not the floor drain itself. When there is a clog in the main building drain and water is run down a drain from an upper fixture, water will back up in the drain line until it finds somewhere else to come out.

How do you stop a floor drain from backing up?

If you do not have a backwater valve, plugs with backflow devices can be installed in floor drains. These plugs have a ball or float that will stop water or sewage from backing up into a home while permitting water to flow into the drain. These plugs can be left in place year-round.

How do I stop water from coming through my basement floor drain?

Install Check Valves to Prevent Flooding Have a plumber install check valves on your floor drains and all of your basement plumbing fixtures. A check valve lets water run out of the drain as designed but prevents water from flowing back into the drain.
