A plumbing inspection in Knightdale is a plumber's look at the water lines, drains, water heater, shutoffs and fixtures, with an optional camera run of the sewer lateral. Most Knightdale homes were built after 2000, so the focus is usually on install quality and wear. Call the number on this page to be connected with a local plumber in Knightdale.
Knightdale conditions that shape an inspection
Knightdale is young. Census survey data puts the median home at 2008, and about 74% of homes were built since 2000, with only around 6% before 1980. For most houses here a plumber focuses on PEX connections, water heater setup, pressure, fixture wear and the slope and condition of the drain line to the street.
Knightdale merged its water and sewer system with the City of Raleigh, so Raleigh Water owns and operates public water and sewer in town. Raleigh maintains the water line up to the property line, and the owner is responsible from there to the house. The water is soft, about 25 ppm hardness, with chloramine most of the year and a short chlorine-only period in spring.
Building and plumbing inspections in Knightdale are done by Wake County Permits and Inspections on the Town's behalf. If a seller says a water heater or fixture was replaced, the Wake County Permit Portal is the place to check whether it was permitted.
Homes outside the Raleigh Water service area may be on private wells. Wells in eastern Wake can carry naturally occurring uranium, radon and radium, and the county estimates about one in five sampled eastern Wake wells is affected, so a well house needs a separate water test.
Town water vs private well: what to check
| Item | On Raleigh Water | On a private well |
|---|---|---|
| Service line | Owner's side from property line to house | Line from the well to the house |
| Pressure | Check for a pressure regulator issue | Pump, pressure tank and switch |
| Water quality | Read Raleigh Water's annual report | Lab test, including the radiological package |
| Backflow | Dual check in meter box; irrigation assembly every three years | Not part of Raleigh's program |
Signs to look for
- A water heater approaching 10 years old, or a newer one with no permit record
- Damp subfloor near the laundry or a bathroom
- Gurgling or slow drains in a house that's otherwise new
- An irrigation system with no backflow test history
Timing notes
Raleigh Water's residential irrigation backflow tests are due every three years by July 1, so a spring closing is a good time to ask whether the next one is coming up. The spring chlorine switch can briefly change how the water smells; that's the utility, not the house.
