In Dunn, a disposal that won't spin, won't start or leaks under the sink is usually jammed, tripped, worn at a seal or simply at the end of its life. With so many older homes in town, a plumber will often check the kitchen drain line behind it too. Call the number on this page to be connected with a local plumber in Dunn.
Warning signs
- A hum with no grinding
- Silence when the switch is on
- Water dripping from the bottom of the unit
- Gurgling, or water rising in the second sink bowl
- Loud rattling that doesn't stop
- Food bits coming back up after grinding
Older kitchens and Dunn's sewer
Dunn's housing is among the oldest in this part of Harnett County. About 66% of homes were built before 1980, the median build year is 1973, and only around 9% went up after 2000, per Census survey data. In a kitchen that old, the disposal may be new while the drain behind the wall is original, with a rough interior that snags ground food. When a sink keeps backing up after the disposal has been cleared, that older line is often the reason.
Everything ground in town goes into the City of Dunn's sewer, which the city says runs about 88 miles and feeds its Black River Wastewater Treatment Facility, permitted for 3.75 million gallons a day. The city aims to clean at least 10% of that collection system each year. Its crews also make sewer taps for new homes and repair sewer services and mains, which matters if a backup turns out to be on the public side rather than in your house. A plumber can usually tell which side the problem is on after clearing the kitchen line.
What affects what you pay
- Whether it's a quick jam or reset, or a full replacement
- The disposal model, from basic to heavier-duty units
- Electrical work, such as a new cord, outlet or switch
- Drain cleaning if the clog is past the trap in an older line
- Replacing a cracked dishwasher hose or connection
- Access in a cramped or damaged sink cabinet
When you make the call
You'll be connected with an independent plumber who works in Dunn. Before they arrive, turn the disposal off and unplug it if you can reach the outlet. Note what it does when switched on and whether other drains in the house are slow too; several slow drains point past the kitchen. Dunn's Planning and Inspections office handles permitting inside the city, and the plumber can tell you whether your project needs a permit.
