Roswell has two water providers, and each runs its own backflow rules: the Roswell Water Utility serves part of the city with an approved tester list, while Fulton County requires testable devices to be checked every year by a certified tester who reports through SwiftComply. Call the number on this page to be connected with a local plumber in Roswell.

What happens when you call
The number on this page puts you in touch with an independent plumber who works in Roswell. Expect a few questions first: which utility's name is on your water bill, what kind of assembly you have, and whether you need a routine test, a repair or a new device. That first answer matters more than usual here, because Roswell's paperwork differs from Fulton County's. If you want the test submitted for you, ask whether the plumber appears on the right utility's tester list.
What affects the cost
- A straightforward annual test versus a rebuild and retest
- Reduced pressure assemblies, which take longer to check than double checks
- Roswell Water Utility's extra steps: before and after photos and a utility data tag
- Parts availability for older or discontinued assemblies
- Access, such as a device buried in landscaping on a sloped lot
Two programs in one city
Roswell's own treatment plant serves only part of the city, roughly 5,600 customers. Everyone else gets water from Fulton County. Your bill is the fastest way to tell which one you're on.
Roswell Water Utility customers. The city keeps an Approved Backflow Tester List. Testers must hold current certification and file test forms within 30 days of the test, with photos taken before and after and a utility data tag attached. Repairs to assemblies are limited to master plumbers holding a state license who have also completed a repair course. Questions go to [email protected] or (770) 641-3707.
Fulton County customers. The county requires testable devices to be tested every year by a certified tester, and repaired if they fail. Results are filed with Fulton County through SwiftComply.
Either way, the assembly sits on the owner's side of the meter. Fulton County's flyer puts the owner in charge of the line from the meter to the house, and the device on that line comes with it. New installs that add piping go through Roswell's Community Development Department, whose permit application asks each trade for a license and affidavit.
Before the plumber arrives
- Find a recent water bill so you can say which utility serves you
- Locate the assembly and clear plants or mulch away from it
- Note the brand, size and serial number from its tag
- Pull out any previous test report or utility letter
- Close the irrigation shutoff if the device is leaking
