Commercial Plumbing
Plumbing for Roswell Businesses
Commercial plumbing covers the systems a business relies on: restrooms that get far more use than any house, kitchen drains and grease lines, and commercial water heaters. It also covers backflow assemblies, gas lines to cooking equipment and the pretreatment systems the county requires. Roswell 24/7 Plumbing works for businesses across Roswell in 30075 and 30076, from the restaurants and shops around Canton Street to offices along Holcomb Bridge Road and the GA-400 corridor.
The difference from residential work is mostly about time and rules. A clogged drain in a restaurant is lost revenue by the hour, so emergencies are answered 24/7 and planned work is scheduled around opening hours. And businesses deal with requirements homes do not, especially grease pretreatment and annual backflow testing.
Honest note on scope: this is light commercial work. Large new-construction projects and high-rise systems are outside what we take on.
Fulton County's Grease and Pretreatment Rules
Most of Roswell's businesses discharge into Fulton County's sewer, and the County has specific rules for commercial waste. Its code requires food service businesses that prepare food commercially to provide an approved fats, oils and grease pretreatment system, such as a grease trap or interceptor. Vehicle service and car wash facilities need an oil separator or sand trap.
The County's Commercial Pretreatment program monitors and inspects these systems and requires a permit for facility operations. New or modified grease traps go through plan review, with sizing based on the County's sewer use ordinance, often tied to seating capacity.
For a restaurant owner, that means three things: a correctly sized trap, a pumping schedule that keeps it within limits, and records to show an inspector. Grease that gets past the trap still ends up coating the building's drain lines, which is where jetting the kitchen lines comes in.
The IPC, which Georgia's state minimum plumbing code is based on, also sets minimum restroom fixture counts by occupancy type and calls for grease interceptors where grease-producing fixtures drain. That means a kitchen remodel or change of use can trigger both a County review and code upgrades.

What to Do Before We Arrive at Your Business
These steps limit downtime and damage during a commercial plumbing emergency.
- Know your shutoffs. Every manager on shift should know where the main and fixture shutoffs are.
- Stop water use on backed-up drains. Close affected sinks and restrooms and post a sign.
- Protect electrical equipment. Keep water away from panels, POS systems and kitchen equipment.
- Have the trap records handy. For grease-related backups, the pumping log helps diagnose the cause.
- Name an approver. Tell the dispatcher who can approve the work and the price.
Emergencies are answered 24/7, and repairs can often be finished before the next opening.

Timing and access matter as much as the repair itself.
Planned projects get a free estimate. Nearby Sandy Springs has a large office and retail base with similar needs, though its permitting runs through its own city.
