Backflow Testing in Linwood, NC

Who sets the rules for my Linwood address?

Linwood is an unincorporated community just south of Lexington along I-85, and parts of it, mainly the industrial area, have been annexed into Lexington. Water can come from Davidson Water, the large non-profit rural system serving about 62,000 connections across Davidson County, or from City of Lexington Utilities, which also serves customers around the county. Which one serves a given street wasn't confirmed, so look at your bill. If it's from the City of Lexington, follow the City's rules instead of the ones below.

What does Davidson Water require?

Davidson Water runs a cross-connection program for its members. It decides through inspection whether a property has a backflow risk, and it names common examples: irrigation systems, fertilizer injectors, and connections to well water. Where a risk exists, a backflow device is required. That device must be tested every year by an approved tester, and it must be retested after any repair. So a Linwood home with a sprinkler system on Davidson Water should expect a yearly test, and one that runs fertilizer through the irrigation should expect closer attention to the device type.

Why does a well connection matter here?

Davidson Water specifically flags homes that have both its water and a well. A house that used a well before public water arrived may still have it tied into the household plumbing, and that well could push untreated water back toward the public system. Davidson Water treats that as a backflow risk needing protection. The cleaner fix is often to separate the well completely and use it only for outdoor or farm needs, if at all. A local plumber can trace the piping and show you where the two systems meet.

Local note

Linwood housing is mostly from the 1980s through the 2000s, with a median build year of 1989. Permits for plumbing work go through Davidson County's online building permits portal, though Lexington-annexed parts may fall under the City instead.

When you call, you'll be connected with an independent plumber who works in Linwood and the Lexington area. It helps to know which utility bills you, whether the irrigation runs any fertilizer or chemical feed, and whether a well is still on the property. With those answers, the plumber can tell you whether you need a yearly test, a repair and retest, or a separation job.
