A Kennesaw business gets its water from Cobb County Water System, which requires yearly tests of the backflow assembly on every non-residential connection, and the City of Kennesaw's Building Services Department permits plumbing work under the 2024 International Plumbing Code with Georgia amendments. Call the number on this page to be connected with a local plumber in Kennesaw.

Kennesaw grew around the railroad and Kennesaw Mountain, and today its commercial plumbing runs from restaurants and retail along Cobb Parkway and I-75 to offices on Moon Station Road and rental houses near Kennesaw State University. Most buildings are fairly young; the median home dates to 1998 and only about 11% were built before 1980.
What to do in the first few minutes
- Shut off the water feeding the problem. Use the fixture stop if there is one, or the building's main valve. Cobb County Water System owns the line only up to the meter, so the valve inside or at the wall is yours to operate.
- Protect people and equipment. Keep staff and customers away from wet floors near outlets, coolers and point-of-sale gear.
- Figure out whether it's one fixture or the whole building. Several drains backing up together usually means the building sewer.
- Look outside if sewage is involved. An overflowing manhole or a break in the street goes to Cobb's emergency line, 770-419-6201.
- Write down your business hours. The plumber will want to know when a restroom or kitchen can be taken out of service.
Common symptoms and what usually causes them
| Symptom | Likely cause |
|---|---|
| Kitchen floor drain slow by the end of every shift | Grease and food solids coating the line |
| Restroom toilets that keep running | Worn flush valves or flappers |
| Hot water fading during a rush | Undersized heater, sediment or a failing element |
| A backflow test notice from Cobb | Annual test due on the assembly at the connection |
| Wet pavement between the meter and the wall | Leak on the owner's side of the service line |
What drives the cost
- How many fixtures, units or tenants the problem reaches
- Whether a camera or leak locator is needed to find the cause
- Scheduling outside business hours so the space can stay open
- Access through drop ceilings, finished walls or a slab
- Permit and inspection steps with Kennesaw Building Services, which takes all applications online
- Repair parts if a backflow assembly fails its test
Cobb's program requires a testable assembly on every non-residential water connection, tested yearly by a tester registered with the county, so budget that test as a standing annual item.
