Commercial plumbing is the repair and upkeep of the drains, water heaters, restroom fixtures, gas piping and backflow assemblies that let a business or rental building stay open. In Atlanta, every commercial water customer must also have a backflow prevention assembly with test reports filed by a registered tester. Call the number on this page to be connected with a local plumber in Atlanta who handles commercial jobs.

The calls businesses make most
- Kitchen lines choked with grease in the middle of a dinner rush
- Flushometer valves, urinals and sinks worn out by constant use
- Large tank or multiple tankless water heaters that cannot keep up
- Main drain stoppages and damaged laterals under paved lots
- Leaks in apartment or office buildings that travel between units
- Gas piping for cooking equipment, boilers and rooftop units
Backflow is not optional for commercial accounts
The City of Atlanta Department of Watershed Management requires an assembly at every commercial water customer, installed near the meter box or just inside the building ahead of the first branch line. Test results must be submitted by a registered tester through the SwiftComply system, and a fee applies to passing reports. Since the City's page does not set out one testing interval for every site, follow the dates on any notices DWM sends and keep your own record of each test. Fire lines, irrigation and specialty equipment can mean more than one assembly on a property.
Keeping the doors open during repairs
Downtime is the hidden cost on most commercial jobs. Before anything breaks, find out where the main shutoff and any zone or floor valves are, label them, and make sure staff on every shift know. A plumber who can isolate one restroom or one riser instead of the whole building saves you hours. Ask about early-morning or after-close scheduling for planned work, and confirm availability when you call since it varies.
Preventive work pays for itself. Scheduled jetting of kitchen lines, flushing water heaters, checking for slow drips above drop ceilings and walking the building for running fixtures all cost less than an emergency closure. Owners of several properties often keep notes on each building's shutoffs and history so whoever responds can get to work quickly.
Permits
Plumbing permits inside the city run through the City of Atlanta Office of Buildings. The online technical permit with no plan review that the City describes is for one- and two-family homes, so a commercial job may follow a different path. Ask the plumber who will pull the permit and how inspections will be scheduled around your hours.
What drives the cost
Price depends on building size, pipe sizes and materials, access above ceilings or under slabs, permit needs, the number of backflow assemblies, and whether the work has to happen outside business hours.
