Local conditions

Drains & sewer in Newark: what's different

Heavy rain can overwhelm Newark's combined sewers and back water up through basement floor drains. Two- and three-family buildings put heavy use on shared drains.

Cast-iron drains in pre-1950 homes crack and clog.

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

Old laterals in dense neighborhoods like the Ironbound often run under sidewalks to mains in the street, and the lateral belongs to the owner. A backwater valve helps in homes that see storm backups.

Other Newark conditions that affect plumbing

  • Lead service line replacement: Newark replaced more than 20,000 lead service lines starting in 2019. Older homes may still need interior plumbing updated where lead or galvanized pipe connects.

  • Multi-family wear: Two- and three-family buildings put heavy use on shared drains and water heaters.
  • Interior pipe after service line replacement: Once the lead line from the street is replaced, older Newark homes may still have galvanized or lead-soldered pipe inside, which plumbers often replace at the same time to get the full benefit.

Drains & sewer questions in Newark

Why does my Newark basement drain back up in storms?

Combined sewers can overflow during heavy rain. A backwater valve helps.

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.
