Main Line, Sewer & Cesspool Backups in Centereach, NY

Quick answer: Most of Suffolk County is not on public sewers, so a backup in a Centereach-area home is often a cesspool or septic issue, not a sewer main. A plumber can clear and camera the line from the house to the system. Pumping and replacing cesspools and septic systems is done by licensed liquid-waste contractors, and in Suffolk a failed cesspool can no longer be replaced with another cesspool.

Common questions

Pipe problem or cesspool problem?

A camera inspection of the line tells you. If the pipe is clear and water still won't go, the cesspool or septic system is likely full or failing.

Can I replace a failed cesspool with a new cesspool?

No. Under Suffolk County's Sanitary Code (Article 6) a replacement must be at least a septic tank followed by a leaching structure, with Health Department filing. See our guide.

Are there grants?

Suffolk County and New York State offer grants toward advanced (I/A) systems that replace cesspools and septic systems for eligible homes. See suffolkcountyny.gov/septicgrants.
