An Erwin disposal that hums, won't start or leaks usually has a jam, a tripped reset, a failed seal or a worn motor. Since about two-thirds of Erwin homes predate 1980, the kitchen drain can be part of the problem. Call the number on this page to be connected with a local plumber in Erwin.
Erwin's homes and utilities
Erwin grew up as a cotton-mill town on the Cape Fear River next to Dunn, and its housing is old. The median home was built in 1966, roughly two-thirds were built before 1980, and about 24% date to 1939 or earlier, per Census survey data. Kitchen drains in houses that age are often original, with buildup that catches ground food. Erwin has no town water or sewer department; Harnett County bought both systems in 2006, so sewer service and billing go through Harnett Regional Water.
In older Erwin kitchens, it's common to find a modern disposal connected to a much older trap and drain stub, sometimes metal pipe that has corroded or narrowed from the inside. A disposal sends fine food slurry into that line every time it runs, and the slurry settles wherever the pipe is rough. That's why a plumber called for a disposal problem in a mill-era house will often check and clear the kitchen line as part of the same visit, and may suggest replacing a corroded trap while the cabinet is open. If several fixtures in the house are slow, the trouble may be farther out in the main line instead.
First steps
- Switch the disposal off and unplug it or shut off its breaker.
- Pull out any visible object with tongs, never your fingers.
- Press the red reset button on the bottom if the unit is silent.
- If it hums, free the plate with the hex wrench from underneath.
- If the sink won't drain, stop running water into it; an older drain may be blocked past the disposal.
- Leave chemical drain openers on the shelf.
