Commercial plumbing in Nashville includes drain and sewer clogs, restroom fixtures, water heaters and the backflow assemblies the Town requires commercial and industrial customers to permit and test every year. Nashville buys most of its water from Rocky Mount and sends its sewage there for treatment. Call the number on this page to be connected with a local plumber in Nashville.

When you call
You'll be connected with an independent local plumber who handles commercial jobs in Nashville. They'll ask about the type of business, what's going wrong, which fixtures or floors are affected and when the space can close. If the job involves backflow, have your BSI Online notice or last test report ready.
Permits come in two steps here. The Town issues a zoning certificate of compliance, and Nash County Planning & Inspections handles the building and trade permits. Plumbing, electrical and mechanical permits are separate and are pulled by the contractor doing the work.
What affects the cost
- Scope. One fixture versus a building drain or a main shared by tenants.
- Old lines. Older downtown buildings may need a camera before a fix is chosen.
- Timing. Work outside business hours usually costs more.
- Backflow equipment. A new or replacement assembly plus the required test and filing.
- Permits through the Town and Nash County.
Local conditions in Nashville
Nashville is the Nash County seat, west of Rocky Mount, with a historic downtown of Victorian and Queen Anne homes around Washington Street and mostly 1980s-2000s housing beyond it (median built 1993). Commercial life centers on the courthouse area, Washington Street and Barnes Street, where Town Hall sits.
Nashville Public Utilities buys most of its water, about 80% in 2023, from the City of Rocky Mount and supplements it with town wells, so both chlorine and chloramine show up in the system. The Town maintains 14 sewer lift stations, its mains and outfalls, and sewer laterals within town; wastewater is treated at Rocky Mount's Tar River Regional plant. In a 2024 state grant round, Nashville received $1.5 million for water and wastewater fixes, with the town manager planning to recommend lining manholes and replacing many aging two-inch waterlines.
The Town's cross-connection rules require industrial, commercial and irrigation customers to get a backflow permit and install assemblies on their property before the private plumbing branches. Annual test reports are filed through BSI Online, which mails a notice 32 days before a test is due; since March 1, 2023, each filing carries a $16.95 fee.
