Restaurant Grease Trap Cleaning
in Pomona, CA
Grease traps prevent fats, oils, and grease (FOG) from entering the sewer system. Full traps cause backups, foul odors, and health code violations. Most municipalities mandate a pumping schedule and require disposal manifests.

Best price for Restaurant Grease Trap Cleaning in Pomona
If you find a lower price from a licensed, compliant provider, we'll match it. This is not a race to the bottom — Boh vendors are fully licensed, carry the required CDFA and LA County hauler permits, and issue the mandatory manifest report after every visit. The low price reflects volume efficiency, not corners cut on compliance.
LA County Sanitation Districts set the 25% rule

Grease trap cleaning in Pomona, answered
How often does a Pomona kitchen actually need its grease trap pumped
LA County Sanitation Districts require pumping when grease and solids reach 25% of the trap's hydraulic depth. For birria, carnitas, and mariscos operations — which are the dominant kitchen type in Pomona — that threshold arrives monthly, sometimes faster in summer when Pomona's heat accelerates FOG breakdown.
Why does summer heat affect how often the trap needs service
Pomona sits in the Pomona Valley and regularly sees higher summer temperatures than coastal LA cities. Heat speeds up the decomposition of fats and oils inside the trap, which causes gases to escape sooner and the effective capacity to drop faster. Summer pumping intervals should be shortened, not kept the same.
What fine can LA County Sanitation Districts issue for a FOG violation
The Districts can fine up to $5,000 per violation. Beyond the fine, repeated violations put your sewer connection at risk — a revoked connection shuts the kitchen down entirely.
What records does LA County Sanitation Districts actually want to see
Inspectors typically ask for the pumping manifest, the waste hauler disposal receipt, and a log showing a consistent service interval. All of it must be kept on site for 3 years. Missing any one document is treated as a separate compliance gap.
Do the older downtown Pomona buildings have grease traps that are harder to service
Many of the early 20th-century and mid-century commercial buildings along Garey Avenue were not built as restaurants. Traps in these buildings are sometimes undersized, oddly positioned, or shared between units. A vendor needs to assess access and capacity before establishing a service interval.
What happens if a drain backs up during a dinner service
A backup that reaches the kitchen floor is a health code violation under LA County Environmental Health standards and can trigger an immediate closure order. The underlying cause — a full grease trap — also puts you in violation of the Sanitation Districts' FOG rules simultaneously.
Is grease trap cleaning connected to any other kitchen maintenance
Yes. High-output kitchens that generate heavy FOG loads also tend to accumulate grease in hood systems faster. LA County Fire enforces hood cleaning compliance separately, so kitchens on Holt Avenue or around the Cal Poly Pomona area often need both services on overlapping schedules.
Why is Pomona underserved by grease trap vendors compared to other LA County cities
Most commercial grease trap vendors concentrate routes in denser SGV and central LA County markets. Pomona's independent operator base — heavily Latin American family restaurants rather than chains — gets deprioritized for scheduling. Boh coordinates service through BohPro vendors who already run routes in the eastern county.
