Locust Grove's Department of Public Works manages the city's water and sewer, and our research didn't find a published backflow testing program for its customers, so we can't quote an interval or tester rule. If you're adding irrigation or opening a business, ask Public Works what it requires. Call the number on this page to be connected with a local plumber in Locust Grove.
Local conditions in Locust Grove
Locust Grove is a small, fast-growing city on I-75 in southern Henry County, best known for its outlet center at the Bill Gardner Parkway exit and surrounded by rural land and unincorporated communities such as Luella. The city's Public Works Department, with a Utilities Manager on staff, runs all water and sewer activity, and residents pay one combined monthly bill at the Water Department in City Hall. Henry County Water Authority supplies backup water. Whether addresses in the 30248 ZIP outside city limits are on the county authority instead wasn't verified, so check your bill.
Because Locust Grove runs its own system, the city decides whether a connection needs backflow protection. We didn't find published requirements, so we won't guess at a test interval or a list of accepted testers. Ask Public Works directly. The retail and restaurant cluster around the outlets and Strong Rock Parkway, plus newer subdivisions with irrigation, are the connections most likely to need a device.
New plumbing inside the city goes through Community Development, which offers a Plumbing Permit Application and has a permit technician and a construction inspector on staff. The office is at 3644 Highway 42, behind the LGI Building in the Municipal Complex.
Choosing the right device
| Connection | Common device | What to know |
|---|---|---|
| Plain lawn irrigation | Double check valve or pressure vacuum breaker | A vacuum breaker must sit above the highest head |
| Irrigation with chemical injection | Reduced pressure assembly | Needs room to drain from the relief port |
| Restaurant or car wash | Reduced pressure assembly | Higher hazard, more parts to test |
| Garden hose spigot | Hose bib vacuum breaker | Simple, not testable |
The city's answer on what it requires outranks any general guide, so confirm before buying parts.
Signs to act on
- A request from the city about a device or a test
- A leak at an assembly near the meter
- New sprinklers or a pool fill going in
- A commercial space being fitted out
- Cracked brass after a freeze
Timing notes
Ask about requirements during planning, before a new business or irrigation system is built. Outdoor devices in open, rural-edge lots catch the cold, so drain and wrap them before winter. When you call, have the device's make and size and any letter from the city ready.
