Backflow in Lilburn

Lilburn began as a railroad town in 1890 and is now a diverse southern Gwinnett suburb with a revitalized Old Town. Under a 2018 intergovernmental agreement among Gwinnett County, the county's water and sewerage authority and the city, Gwinnett operates the water and sewer facilities that serve Lilburn. The city's FAQ refers sewer and stormwater matters to Gwinnett DWR as well.

For backflow, contact DWR's backflow staff at 678.376.4213 or DWRBackflow@GwinnettCounty.com. The county sources reviewed for Lilburn didn't verify how often devices must be tested or which testers are accepted, so ask before booking. That's the honest answer, and DWR's is the one that counts.

Gwinnett is responsible for the pipes that bring water to the meter. All plumbing, pipes and fixtures between the meter and the home belong to the homeowner, and that includes a backflow device. Lilburn's median home was built in 1988, and about a quarter of homes predate 1980. Many neighborhoods near Lawrenceville Highway and Lilburn City Park have mature landscaping, and irrigation added years after construction is the most common reason a house here has a device.

New plumbing goes on Lilburn's Building Permit / Compliance Inspection Application, which lists plumbing among the trades included. The city's number is (770) 921-2210.

When you call

You'll be connected with an independent plumber who serves Lilburn. Tell them what the device protects, whether it's leaking and whether Gwinnett has asked for anything. If water is spraying, close the irrigation valve and leave the house supply on. Have the device's make and size handy so the right parts come along.
