Sump Pumps in Dunn, NC

Signs something is wrong

• Water in the crawl space after a storm, and a pit that is full
• The pump motor runs warm and never shuts off
• Frequent cycling with only a little water each time
• A loud thump in the pipe whenever the pump stops
• The pump has shifted in the pit and the float rubs the side
• Mildew on joists or a musty smell inside the house

Dunn's housing and sewer

Dunn started as a logging and turpentine town, and its houses show it. The median home was built in 1973, about two-thirds were built before 1980, and only around 9% went up after 2000, according to Census survey data. In houses that old, a pump was often added later to deal with a wet crawl space, and its discharge pipe may run to a spot that seemed handy at the time rather than one that drains well.

The City of Dunn runs about 88 miles of sewer lines to its Black River Wastewater Treatment Facility, and the city says it aims to clean at least 10% of that system each year. Sump water is groundwater, and it adds load to that system if it ends up in a floor drain or cleanout. A plumber can move the discharge outdoors and slope it away from the foundation.

The city's backflow ordinance covers irrigation, commercial and industrial customers, with assemblies tested annually by certified testers. A water-powered backup sump pump also connects to the drinking water supply, so ask the plumber what protection it needs and whether the city wants to know about it.

Price drivers

After you call

An independent plumber who serves Dunn will take it from there. Say whether water is rising now, where the pit sits and how old the pump is. If it's an emergency, unplug the pump or switch off its breaker from a dry spot first. Dunn Planning & Inspections handles development applications and permits through Cloud Permit, and the plumber can tell you if the work calls for one.
