A plumbing inspection in Coats is a plumber's check of the supply lines, drains, water heater, shutoffs and fixtures, plus an optional camera run of the sewer service. More than half of Coats homes were built before 1980, which makes original pipe a likely finding. Call the number on this page to be connected with a local plumber in Coats.

How much old plumbing is there in Coats?
A fair amount. Census survey data puts the median Coats home at 1978, with about 55% built before 1980. Houses of that era often have galvanized supply lines, early copper and cast iron drains, sometimes with sections replaced over the years. A plumber traces the lines in the crawl space, tests shutoffs, checks the water heater and its venting, and can run a camera through the sewer service.
Who supplies the water and who handles sewer?
Coats doesn't treat its own water. The Town buys Cape Fear River water from Harnett Regional Water through metered connections and distributes it to about 970 customers over roughly 29 miles of lines. The 2025 water quality report found no detectable lead or copper at the 90th percentile, no homes above action levels and no violations. The Town has also prepared a service line inventory, available from the Town, so you can ask how the address is listed.
A 2018 county presentation says Harnett County owns the wastewater system in Coats. That arrangement wasn't re-confirmed on a current page, so if a camera run finds a problem near the street, ask Harnett Regional Water where its responsibility begins.
Where do permits come from?
Plumbing permits and inspections in Coats go through Harnett County Inspections, but the Town grants a zoning permit first; the county won't issue a building permit without it. If a seller mentions recent plumbing work, the county's Central Permitting office can tell you whether a permit is on file.
The 27521 ZIP reaches well beyond town limits, and homes outside town may be on Harnett Regional Water directly or on private wells.
Local note
Gas in Harnett County comes from Piedmont Natural Gas where lines reach. If a house has gas appliances and you smell gas, leave and call 911 or Piedmont's emergency line, 800-752-7504, from outside. For the inspection itself, have the crawl space open, the water on and any repair receipts from the seller on hand. Older Coats homes often have a story behind each patch, and the receipts help the plumber read it.
