Questions From Kitchen Owners
How often does my grease trap need to be pumped in San Diego?
Most commercial kitchens need service every 30–90 days. The standard across Southern California is the “25% rule” — your trap must be cleaned before fats, oils, grease and solids reach 25% of its capacity. Your city sets your exact cycle; we track it for you and schedule automatically.
Do you file the waste manifest for me?
Yes — every single service. Your manifest is completed on-site, filed with your local FOG program where required, and stored in your digital records. When an inspector asks for documentation, you’ll have years of it, organized.
Do you actually do plumbing repairs too?
Yes. That’s the whole point of OH. Grease haulers can’t fix your floor drain and plumbers won’t pump your trap — we handle both, from interceptor installs and permits to backflow tests, hydro jetting, and emergency repairs.
What areas do you serve?
We’re headquartered in San Diego at 455 Frazee Rd and serve San Diego, Orange, Riverside, San Bernardino, Los Angeles, and Ventura counties.
Are you available for emergencies?
24/7, 365. Backups, overflows, and failed inspections don’t wait for business hours, and neither do we. Call (888) 557-7997 any time.
What does grease trap cleaning cost?
Standard traps start at $225 and interceptor pricing is quoted by size before we roll a truck. Your price is confirmed before any work begins.
