How commercial drains differ from homes
Commercial lines carry more volume and different waste: kitchen grease and food solids, floor drain sediment, paper from busy restrooms. Pipes are larger, runs are longer, and several tenants may share one line.
We bring larger cables and jetters for commercial pipe, camera lines that keep clogging, and write up what we find so property managers and tenants can see where the problem is and who it affects.
Warning signs
Signs a commercial line needs attention

- Backups at the lowest drainMain or building drain blockage.
- Grease smell from drainsGrease buildup downstream of the trap.

- Restroom fixtures gurglingVenting or partial blockage.
- Clogs after busy daysLine undersized or narrowed by buildup.
Timing
How long the business is affected
Most commercial clogs are cleared in a single visit of a couple of hours, and fixtures are usable again once the line runs clear.
Camera inspections and jetting add time, which is why we schedule them outside opening hours whenever the backup allows.
Restaurant grease lines
Restaurant drains clog with grease that slipped past the interceptor and hardened in the line. A cable opens it; jetting cleans it. We jet from the nearest cleanout until the water runs clear, camera the line to confirm it, and check the interceptor, since a trap overdue for pumping is the usual source. Scheduling after close or before prep keeps the kitchen running, and a regular jetting interval, set from what the camera shows, stops the midnight backups that cost a full service.
Floor sink backups
Floor sinks and floor drains in kitchens, bars and back rooms collect sediment, food waste and debris that eventually block the trap and the line. When one backs up, the water often comes up at the lowest drain in the building. We clear the line, clean the floor sink strainer and trap, and camera the branch when backups repeat. Dry floor drain traps that let sewer gas into a dining room or restroom are refilled or fitted with trap primers so the smell does not return.
Multi-unit stack clearing
In apartment and mixed-use buildings, one blocked stack or building drain can back up into several units at once. We find the blockage by working from the lowest affected unit and the building cleanouts, clear it with a cable sized for the stack, and camera it to see whether the cause is a single tenant's waste or a defect in the pipe. The written findings help property managers decide on repairs, schedule any follow-up work, and explain clearly to tenants what happened and why.

Local context
Commercial calls out of the Fairgrounds district
Commercial backups are timing problems as much as plumbing problems, which is where our location helps. The service office at 332 Phelan Ave is off Monterey Road in the Fairgrounds district, close to the Tully Road corridor, so a truck can reach businesses toward downtown quickly after a kitchen closes or before a building opens. We book those windows first and keep daytime calls for the backups that cannot wait until close.
