When's my trap due?
Pumping too late risks a backup and a fine; paying for pumps you don't need yet is money down the drain. This gives you a realistic interval to plan around, then you can get matched with a vetted pumper when you're actually due.
Tell us your trap size and how hard your kitchen runs. We'll estimate your pump interval and the rule your inspector goes by. Guidance only, not a substitute for your city's ordinance.
How the estimate works
Two things drive how fast a trap fills: its size and how hard the kitchen runs. A small under-sink trap behind a busy fryer line fills in weeks; a large interceptor on a light cafe load can go months. The estimate blends those two, then holds everything against the legal trigger your city actually enforces.
That trigger is the 25 percent rule. Once fats, oils, grease and settled solids reach a quarter of the trap's working depth, the trap stops doing its job and you are out of compliance. Many local FOG ordinances also set a hard ceiling, commonly 90 days, no matter how light your load looks on paper.
