A tankless water heater is doable in most Benson homes, though about 42% were built before 1980 and those often need new venting and a larger gas line. Benson handles its own building permits through an online system. Call the number on this page to be connected with a local plumber in Benson.
What happens on the call
The number connects you with an independent plumber serving Benson and southwest Johnston County. You'll be asked whether you want a new tankless unit or service on an existing one, what fuel you have, and how many bathrooms the house has. If you're dealing with a problem, describe it as specifically as you can: no hot water at all, hot water that comes and goes, or a code on the display. For a conversion, the plumber will want to see where the current heater sits and how it vents.
The Town of Benson handles building permits and inspection scheduling through Cloudpermit, so permitted work in town goes through the Town.
Cost drivers
- Gas line size from the meter, often too small in older homes
- New dedicated vent, and capping any shared flue
- Heater location relative to an exterior wall
- Electrical work, minor for gas units and major for whole-house electric
- Condensate drain for high-efficiency models
- Repair parts and diagnostic time
Benson homes and water
Benson's median home was built in 1988, but about 42% of houses date from before 1980, per Census survey data. Newer houses usually have a garage or exterior wall close to the heater. Older homes in and around the historic district may have heaters in interior closets, where a vent run takes more planning.
The Town blends water bought from three suppliers: Johnston County's two systems, drawing on the Neuse River, and the City of Dunn, drawing on the Cape Fear. The 2025 report lists chloramine disinfection but no hardness figure. Because the blend can shift, watch the first descaling to set your schedule.
Johnston County is in Piedmont Natural Gas territory, with availability depending on the street. Outlying homes in the 27504 area may be on wells, and well water should be tested before a tankless unit goes in, since minerals and sediment shorten the time between services.
Checklist for the visit
- Note the heater's age and whether it's gas or electric
- Clear space around the heater, meter and electrical panel
- Have any error codes written down
- Know whether you're on town water or a well
- If you smell gas, leave the house and call 911 or Piedmont at 800-752-7504 from outside
