Drains & sewer in Raleigh, NC

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 Raleigh

Local conditions

Drains & sewer in Raleigh: what's different

Clay laterals in historic Oakwood and Five Points crack and collect roots. Tropical storms moving inland bring heavy rain that tests sewer lines.

A camera inspection shows the lateral's condition.

If a clog keeps returning, a camera inspection shows whether the line needs lining or replacement. Newer neighborhoods have PVC drains with fewer root problems, but red clay soil can still cause sags. City of Raleigh Water maintains the public sewer, and permits come from the City of Raleigh or Wake County.

Scoping before buying in historic neighborhoods is common.

Drains & sewer questions in Raleigh

Why do older Raleigh sewer lines clog?

Roots in clay laterals.

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.
