In Princeton, a disposal that hums, won't start or drips usually has a jam, a tripped overload, a worn seal or a motor near the end. With most homes built before 1980, the kitchen drain behind it is worth checking too. Call the number on this page to be connected with a local plumber in Princeton.

About Princeton's sewer and homes
Princeton, on US 70 between Selma and Goldsboro, runs its own wastewater treatment plant, which discharges to the Little River. The town has been expanding that plant with USDA funding, and it says the state has lifted the sewer moratorium that had been in place. Whatever goes down a Princeton kitchen sink ends up there, and grease and heavy food solids are the part that clogs lines along the way.
The town's homes skew older: about 57% were built before 1980, with a median build year of 1977, per Census survey data. In houses that age, the drain under the sink and behind the wall may be original and narrowed with buildup. A new disposal can grind perfectly and still leave a slow sink if that line can't carry the slurry.
The 27569 ZIP is far larger than the town, and rural homes there are a mix of Johnston County water and private wells. Some aren't on municipal sewer, which changes how a disposal should be used.
Princeton's older kitchens also tend to have older traps and slip-joint fittings under the sink. When a disposal is replaced, a plumber will often swap a worn trap at the same time, since a fresh unit connected to a brittle trap is a common source of slow drips into the cabinet.

Timing notes
Big holiday meals are hard on older kitchen drains, so it helps to scrape most scraps into the trash before rinsing. We couldn't confirm which office issues plumbing permits for Princeton, though Johnston County Inspections is likely; the plumber can tell you whether your job needs one.
