Backflow Testing in Oxford, NC

How the call works

You'll be connected with an independent plumber who takes jobs in Oxford and around Granville County. Describe the setup: a sprinkler system, a pool fill, a fire sprinkler line in an older building, or an assembly that's leaking. Mention whether anyone has asked you for a test report, such as an insurer, a property manager or the City. The plumber can then tell you whether you need a test, a rebuild, a replacement or a device where none exists. If water is spraying from the device, close the valve that feeds it.

What sets the price

• Whether you need a test, a repair kit and retest, or a new assembly
• The type and size of the device
• Freeze or corrosion damage on older brass bodies
• How hard the device is to reach in a box, crawl space or basement
• Permits through Granville County Inspections for new plumbing work

Backflow in Oxford

Oxford's Water and Sewer Department provides drinking water, maintains water and sewer lines and handles every water meter in the city. Oxford also co-owns the Kerr Lake Regional Water System with Henderson and Warren County and buys water from it in bulk; the regional plant is being expanded, which will double Oxford's allocation from 2 to 4 million gallons a day. What research didn't find is any cross-connection ordinance or backflow page on the City's site. That doesn't prove there's no requirement, so if you have irrigation or a commercial connection, call the department and ask.

Why it matters is easy to see from Oxford's own history. In June 2017, pump failures at the Kerr Lake Regional plant cut service to about 54,000 users, and Oxford went under emergency conservation and a boil-water advisory. A sudden pressure loss like that is exactly when water can flow backward from a garden hose, sprinkler zone or chemical tank into the pipes. A device on those connections is the defense.

Housing is old here. About 56% of Oxford homes were built before 1980 and about 17% before 1940, so many houses near the Oxford Historic District and along Williamsboro Street have outdoor spigots with no vacuum breaker at all. Irrigation added to those homes later may have gone in without a proper assembly.

Quick checklist before the visit

• Find the irrigation or pool fill shutoff
• Photograph the existing device and its tag
• Note when it was last tested, if ever
• Check whether outdoor spigots have vacuum breakers
