Why Do Commercial Drains Keep Clogging?
If your drains keep backing up, the problem usually isn’t just a single blockage—it’s a deeper issue within the system. Many businesses experience repeated clogs because the underlying cause hasn’t been fully addressed.
Midway Sewer Service works with commercial properties across St. Paul and Minneapolis to diagnose and resolve these recurring drain issues with the right tools and approach.
The Most Common Causes of Repeat Drain Clogs
Grease Buildup
In restaurants and commercial kitchens, grease is the number one cause of recurring clogs. It sticks to pipe walls, gradually narrowing the flow until drains slow down or back up.
Why it keeps coming back:
Basic cleaning methods may open a path through the grease but leave residue behind, allowing buildup to return quickly.
Debris Accumulation
Floor drains and utility lines collect dirt, food waste, soap residue, and other materials over time.
Why it keeps coming back:
Without thorough cleaning, debris continues to collect in low-flow areas and creates repeated blockages.
Tree Root Intrusion
In older sewer systems—common throughout St. Paul and Minneapolis—tree roots can enter pipes through small cracks and expand inside the line.
Why it keeps coming back:
Roots regrow after being partially cleared unless fully removed and properly treated.
Improper Cleaning Methods
Many recurring clogs are the result of incomplete or temporary fixes.
Why it keeps coming back:
Snaking or basic clearing tools may punch a hole through the blockage but leave buildup along the pipe walls.
Why Temporary Fixes Don’t Work
When a drain is only partially cleared, the remaining buildup acts as a base for new debris to attach to. This leads to a cycle of:
- Slow drainage
- Temporary clearing
- Quick recurrence of the problem
Breaking this cycle requires addressing the full pipe—not just the immediate blockage.
How Hydro Jetting Solves Recurring Drain Problems
Hydro jetting uses high-pressure water to clean the entire interior of the pipe, removing grease, sludge, and debris completely.
Benefits of hydro jetting:
- Cleans full pipe diameter
- Removes stubborn grease and buildup
- Reduces repeat clogs
- Restores proper flow

How Sewer Camera Inspections Identify the Real Issue
Before cleaning, it’s important to know exactly what’s causing the problem. Sewer camera inspections allow technicians to see inside the pipe in real time.
What inspections can detect:
- Grease buildup
- Root intrusion
- Pipe damage or misalignment
- Hidden blockages
This ensures the right solution is used the first time—without guesswork.
