Why do commercial drains clog faster than residential ones?
A commercial kitchen or multi-tenant building runs far more volume through the same size pipe as a house, and grease, food solids, and cleaning chemicals coat the inside of the branch lines faster than a household ever would. A floor drain that backs up during a lunch rush or a mop sink that will not clear is almost always a branch line loaded with buildup rather than a single blockage.
- Kitchen branch lines coat with grease long before they fully clog
- Floor drains in back of house areas take the heaviest solids load
- Multiple tenant lines tying into one building drain multiply the buildup
- A repeat clog on the same line points at the pipe wall, not a one-time object
Call for commercial drain service when
- A floor drain backs up during service hours
- Kitchen sinks or mop sinks drain slower every week
- The same branch line has clogged more than once this year
- A tenant reports a slow drain that a plunger will not fix
- You smell sewer gas near a floor drain or grease trap area

How a commercial drain visit runs
- 1
Identify the affected line
We find out which fixtures or drains are backed up and locate the nearest access point.
- 2
Choose the tool
Cable for a soft clog, hydro jet when grease or scale is coating the pipe wall.
- 3
Clear and test
Restore flow and run enough water to confirm the line holds under real use.
- 4
Camera on repeat clogs
A line that keeps clogging gets a scope so you see the pipe, not a guess.
- 5
Recommend next steps
If the branch line is damaged or the building drain needs jetting on a schedule, we quote that separately.
