Close Affected Food Operations
Close affected food operations when wastewater enters the facility. Keep people away from contaminated surfaces and stop connected fixtures. Seattle Public Utilities advises businesses with a backup to close and contact Seattle-King County Public Health for direction.
Where a FOG Backup Develops
Backups can form in the trap inlet, interceptor outlet, branch drain, side sewer, or public system. Grease deposits often combine with food solids and other debris, creating a dense restriction that basic plunging cannot remove.
Backup Diagnosis and Clearing
Seattle Plumbers checks the interceptor level and accessible cleanouts to locate the affected section. Service may include:
- Pumping or cleaning the grease interceptor
- Mechanical drain cabling
- Hydro jetting suitable grease-waste piping
- Camera inspection after flow is restored
- Inspecting damaged baffles or outlet parts
- Documenting recommended maintenance
Contaminated surface cleanup and food-safety decisions may require specialized providers and public-health direction.
Prevent Repeated FOG Backups
Maintain the interceptor before accumulation reaches its limit. Collect fryer oil separately, scrape plates and cookware, avoid prohibited additives, and keep a dated cleaning log.
Frequently Asked Questions
Can the kitchen reopen after the drain flows?
Public-health and sanitation requirements govern reopening after wastewater contamination. Restored plumbing flow is only one part of recovery.
Why did the backup return after cabling?
Cabling may open a narrow path while grease remains on pipe walls. Further cleaning and camera inspection may be needed.
