Grease Trap Cleaning in Irvine, CA
A grease trap that's overdue doesn't wait for a slow moment to back up, it fails during service. We keep Irvine kitchens on a schedule that keeps that call from happening in the first place.
The 25% Rule Most Kitchens Don't Track
Every grease trap has an industry standard threshold behind it: pump the unit once fats, oils, grease, and solids reach a quarter of its total depth. That's the "25% rule," and it's the benchmark most local health codes and wastewater agencies reference. The trouble is that few kitchens actually check the fill level on a schedule, so the threshold gets crossed quietly, weeks before anyone notices a slowdown at the dish pit, which is exactly the gap our local drain cleaning experts are called in to close. This page covers grease trap cleaning specifically, the small, point-of-use units installed under a sink or just outside the kitchen, typically handling under 50 gallons and common in cafes, food trucks, and smaller kitchens. Higher-volume kitchens often run a much larger underground grease interceptor instead, which we also service, but the maintenance rhythm and code requirements differ enough that it's worth knowing which one your kitchen actually has.
Once a trap fills past that threshold, the consequences compound in a predictable order. FOG starts passing downstream instead of being contained, where it cools and solidifies inside the lateral line running from your kitchen to the sewer connection. That produces slow-draining sinks first, then a rancid odor near the fixture, and eventually a full backup, almost always during active service rather than during a quiet stretch, because peak kitchen hours are exactly when the trap is under the most load.
Irvine's food-service establishments, from independent cafes in older shopping centers to larger kitchens in newer commercial developments, fall under local FOG discharge control requirements enforced through the county sanitation district. Health inspectors routinely check for a documented maintenance history during their visits, which means the trap isn't just a plumbing fixture, it's a compliance record that either exists or doesn't when someone asks to see it.
How We Handle Grease Trap Service
Volume and Trap Assessment
We check the current fill level against the 25% threshold and factor in your kitchen's volume and trap size to confirm the right service interval.
Pump-Out and Cleaning
FOG and solids are fully removed from the trap, restoring its complete capacity rather than a partial clearing that leaves residue behind.
Disposal Documentation
Waste is hauled off and disposed of at a licensed processing facility, with documentation available for your health inspector or landlord.
Recurring Schedule Setup
If you're not already on one, we'll recommend a realistic interval and set you up on a recurring route so service happens automatically.

Signs Your Trap Is Past the 25% Threshold
- Slow drains near the dish pit or prep sink: A noticeable delay in drainage right around service hours is often the earliest sign of a trap nearing capacity.
- Rancid or sour odor near the trap or floor drain: A persistent smell that wasn't there before usually means FOG has started breaking down inside the unit.
- More than 90 days since documented service: Even lighter-volume kitchens should have a check within that window, and most fryer-heavy kitchens need it sooner.
- No maintenance record to show an inspector: A kitchen without documented pump-out history can't demonstrate compliance during a routine health inspection.
Grease Trap or Grease Interceptor: Which Do You Have?
The two terms get used interchangeably, but the equipment and the maintenance rhythm behind them are quite different. A grease trap is a small, point-of-use unit installed under a sink or just outside the kitchen, typically handling under 50 gallons, common in cafes, food trucks, and smaller kitchens where volume is modest enough that an under-counter unit can keep up. A grease interceptor is a much larger unit, usually installed underground outside the building, and serves higher-volume kitchens where code often requires that scale of capacity. Both need regular service, but a trap's smaller volume means it fills faster relative to its size and needs more frequent attention, sometimes monthly for a busy fryer-heavy kitchen, while an interceptor's larger capacity generally stretches its service interval out further. We service both, and if you're not sure which one sits in your kitchen or your parking lot, that's a five-minute conversation before we ever schedule a visit.
Recurring Routes Built Around Kitchen Hours
Most of our commercial grease trap accounts run on a recurring schedule rather than a one-off basis, and we structure that schedule around your kitchen's actual rhythm. Service happens before opening, after close, or during slow windows, whichever fits your operation, and recurring accounts can lock in a standing time slot so it's never something your staff has to remember to schedule.
Every pump-out includes disposal at a licensed waste-processing facility, never on-site and never into the storm system, with documentation available alongside your service record. That paperwork matters when a health inspector asks for maintenance history, or when your landlord's lease terms require proof of regular service.
Background-checked technicians, upfront flat-rate pricing before work begins, and 18 years serving Irvine's commercial kitchens back every visit. If a trap we've serviced backs up or shows signs of incomplete pumping within the guarantee period, we return and correct it at no extra charge.
What Irvine Restaurant Owners Ask Us
What's the difference between a grease trap and a grease interceptor?
A grease trap is a small, point-of-use unit installed under a sink or just outside the kitchen, typically handling under 50 gallons, common in cafes, food trucks, and smaller kitchens. A grease interceptor is a much larger, usually underground unit that serves higher-volume kitchens and is often required by code at that scale. We service both, but this page covers grease trap cleaning specifically.
How often does a grease trap need cleaning?
Most Irvine kitchens need service every 30 to 90 days, based on the industry standard "25% rule," pumping the trap once grease and solids reach a quarter of its total depth. Fryer-heavy kitchens, high-volume restaurants, and undersized traps often need monthly visits, while lighter-volume cafes can sometimes stretch to a quarterly schedule.
How much does grease trap cleaning cost?
A standard grease trap pump-out in Irvine typically runs $145 to $310, with recurring accounts priced lower per visit. Exact pricing depends on trap size, how long it's been since the last service, and whether we're clearing an active backup. We quote a flat rate before any work begins, no surprise line items on the invoice.
What happens if a trap isn't cleaned regularly?
Neglected traps fill past capacity and start passing FOG downstream, where it cools and solidifies inside your lateral line. That leads to slow kitchen drains, rancid odors near the sink, and eventually a full backup, usually during service, which is the worst possible time. Chronic neglect can also trigger surcharges or violations from the local wastewater agency.
Is this required by health department regulations?
Yes. Food-service establishments in Irvine fall under local FOG (fats, oils, and grease) discharge control requirements enforced through the county sanitation district, and health inspectors routinely check for a documented maintenance history. Keeping your trap on a regular schedule with paperwork to show for it is part of staying in good standing on both fronts.
Can you set up a recurring schedule?
Yes, and most of our commercial accounts run this way. We'll assess your kitchen's volume and trap size, recommend a realistic interval, and put you on a recurring route so service happens automatically, no need to remember to call. Recurring accounts also get a reduced per-visit rate compared to one-off calls.
How is the removed grease disposed of?
Pumped waste is hauled off in our service vehicle and disposed of at a licensed waste-processing facility in accordance with local and state regulations. We never dump grease waste on-site or into the storm system, and we can provide disposal documentation alongside your service record if your health inspector or landlord requires it.
Can service happen outside our kitchen hours?
Yes. We regularly schedule grease trap service before opening, after close, or during slow windows so it doesn't interfere with prep or service. Just let us know your kitchen's rhythm when you book, and we'll build the route around it, recurring accounts can lock in a standing time slot.
Is grease trap cleaning covered by a guarantee?
Yes. If a trap we've serviced backs up or shows signs of incomplete pumping within the guarantee period, we return and correct it at no extra charge. We stand behind the workmanship on every visit, not just the ones with a big invoice attached.
