What to do now
Protect food areas
If sewage backs up in a food-service area, stop food preparation there and follow your health department’s guidance.
Check the grease interceptor
If the interceptor is full, kitchen drains back up. Note when it was last pumped.
Sewage in food areas
Sewage backup in a food-service area may require stopping food preparation and contacting your health department. Clean and sanitize affected surfaces before reopening.
Common situations
Kitchen grease clogs
Fats, oils and grease harden in lines and cause backups in restaurants and cafeterias.
Restroom clogs
Paper, wipes and foreign objects clog restroom lines in busy buildings.
Floor drain backups
Floor drains can back up when the main line or a branch is blocked.
Repeat problems
Lines that clog often may have damage. See sewer camera inspection.
What to have ready when you call
- Property ZIP code and business type
- Which fixtures or drains are affected
- Whether sewage is backing up
- When the grease interceptor was last pumped, if applicable
- Operating impact and hours
- Who can authorize work and any vendor requirements, such as a COI
How commercial drain cleaning usually works
- Clear the blockage. Cables or jetting clear the clog.
- Jet if needed. Grease-heavy lines are often hydro jetted to clean the pipe walls.
- Inspect repeat lines. A camera shows damage behind recurring clogs.
- Maintenance plan. Scheduled cleaning can prevent backups in busy kitchens and restrooms.
Cleaning drains does not clean up a sewage spill. Contaminated areas need separate cleanup and sanitizing.
