Drains & sewer in Louisville, KY

A single slow sink is usually a local clog a plumber can clear in one visit. Several drains backing up at once, gurgling toilets or water at a basement floor drain point to the main sewer line, which may need cleaning, a camera inspection and sometimes repair.

Local conditions

Drains & sewer in Louisville: what's different

Heavy rain backs up older Louisville sewers, and the floodwall protects much of the city but low areas can still see backups.

Shotgun houses have long, narrow plumbing runs.

Old cast-iron and clay drains in Old Louisville, the Highlands and Germantown crack and collect roots, and basement floor drains are where backups show up first. A camera inspection shows whether a repeat clog needs cleaning or repair. MSD handles the public sewer, and permits come from Kentucky's Division of Plumbing.

Drains & sewer questions in Louisville

Why does my Louisville basement back up?

Old sewers overloaded during heavy rain.

Are chemical drain cleaners safe to use?

They can damage older pipes and fixtures, and they make the job hazardous for the plumber if they don't work. A plunger or a drain snake is safer for a single slow drain.
