Drains & sewer in Buffalo, NY

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.

Drains & sewer services in Buffalo

Local conditions

Drains & sewer in Buffalo: what's different

Buffalo doubles share drains and laterals, so a clog affects both units. Older homes with basement floor drains see backups when laterals clog or combined sewers overflow.

The Buffalo Sewer Authority runs the city's combined sewer system.

A camera inspection shows whether a backup is in the lateral or the public system.

Old cast-iron drains in Elmwood Village and Allentown scale and catch debris, and a clog in a Buffalo double backs up into both units. A backwater valve helps in homes that see storm backups. Work must be done by a Buffalo-licensed master plumber.

Drains & sewer questions in Buffalo

Why does a clog affect both units of my Buffalo double?

They share one sewer lateral.

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.
