How Often You Must Clean It in San Antonio

At least every 90 days; within 2 working days once contents reach 25% of wetted height (under San Antonio City Code Chapter 34 (FOG Ordinance 2011-05-12-0378)). The industry-standard 25% rule applies either way: clean before fats, oils, and grease reach a quarter of your trap's capacity, because past that point grease passes straight through to the sewer. High-volume kitchens (fryers, BBQ, seafood) often need service more often than the minimum.
