Backflow Testing in Mocksville, NC

Does the Town of Mocksville require backflow tests?

No published program says so. The Town of Mocksville Water and Sewer Department treats and distributes water from Hunting Creek, supplemented with water bought from Davie County, and its online material doesn't describe a cross-connection program or a testing schedule. What it does say is practical: in its winter tips, the Town tells owners to insulate backflow prevention assemblies against freezing. That tells you assemblies are out there on town water, so if you have irrigation, a pool fill or a business connection, ask the Water and Sewer Department whether it wants yours tested and how to report it.

What if I'm outside town limits?

Then check your bill before assuming anything. Mocksville's water and sewer service reaches some customers outside town limits, who pay higher outside rates, so an address beyond the town line can still be a Town customer. If your bill comes from Davie County Public Utilities instead, the county's state-mandated program applies: testable backflow devices must be tested annually, and most homes without in-ground irrigation don't need a testable device. Homes on private wells in the surrounding ZIP aren't covered by either utility, and no source counts them.

How do I protect an assembly through a Davie County winter?

Follow the Town's own advice and insulate it. An above-ground assembly on an irrigation line holds water in a brass body and small internal parts, and one hard freeze can split the body or crack a check. Before cold weather, close the irrigation shutoff, open the test cocks or drain valves the way the maker intends, and fit an insulated cover. In spring, reopen it slowly and watch for leaks before the system runs. A frozen device usually needs replacing, not repairing.

Housing in Mocksville is a mix of older in-town homes and a 2000s building boom, with about 28% of homes built from 2000 to 2009. Many of those newer lots came with sprinklers, and their original assemblies are now reaching the age when seals and springs wear out.

A local note on permits

Mocksville contracts with Davie County Planning and Development Services for zoning, permitting and inspections, so permits for new plumbing work, such as installing or moving an assembly, run through the county office on East Depot Street and its online portal.
