Backflow Testing in Holly Springs, NC

If you own a home in a planned Holly Springs community — Holly Glen, Autumn Park, the cul-de-sacs off 12 Oaks — odds are there is a backflow assembly on your irrigation line, and the Town wants it tested every year. Most folks don’t think about it until a letter shows up in the mailbox. That letter is real, and the clock on it is real, so it pays to have a certified tester on call before the deadline crowds in.

Holly Springs grew up fast. The subdivisions that started going in during the late 1990s now sit beside brand-new high-efficiency builds, and that mix shows up in the devices we test. Older irrigation preventers in established neighborhoods like Sunset Ridge tend to need a closer look at the relief valve and check springs, while newer homes near the life-sciences corridor often have assemblies installed within the last few years that simply need their annual certification on file.

What annual testing actually involves

A certified test takes about 20 to 30 minutes per device. We isolate the assembly, attach a calibrated gauge, and verify the checks and relief valve hold pressure the way the manufacturer and the Town require. If everything passes, we certify it and submit the results electronically — you get a copy, the Town gets the record, and you’re set for another year. If a part is leaking or stuck, we’ll tell you exactly what it needs before anything fails an inspection.

Your drinking water in Holly Springs is delivered by Town of Holly Springs Utilities, which buys treated water wholesale from Harnett Regional Water, sourced from the Cape Fear River. Protecting that supply from cross-contamination is why the Town runs a cross-connection control program with teeth.

Here is what the Town requires: backflow devices on irrigation, commercial, and fire-sprinkler connections must be inspected and certified annually. The certified tester — that’s us — submits the results into the Town’s electronic reporting system. Ahead of your annual certification due date, the Town mails a letter as a reminder.

The practical takeaway: when that letter arrives, don’t set it aside. Call us, we test the device, and we file the certification directly so you stay compliant without touching any paperwork yourself. If you’re unsure whether your property even has a device that needs testing, we’ll confirm it for you.
