Grease Trap Probiotics
The video is about probiotic and enzyme products sold for grease traps and kitchen drains. The pitch is that bacteria digest fats, oils, and grease so the box never has to be pumped, or so the odor drops between pump-outs. Some of those products do soften a thin film or cut a smell. None of them is a vacuum truck. A trap that has a foot of floating grease and a layer of sludge still has to be emptied by a pumper.
An interceptor works by time and stillness, or, in a small hydro-mechanical box, by baffles and flow control. Fat floats. Solids sink. The outlet takes cleaner water from the middle. Bacteria do not restore a missing baffle, open a blocked outlet tee, or shrink a full tank overnight. A dose poured into a floor sink is also easy to wash straight through before it does anything, especially if the kitchen uses a sanitizer that kills the culture you just paid for.
Cities that run a fats, oils, and grease program write the interval in the permit or judge it from the twenty-five percent rule: when the floating cap plus the sludge reaches about a quarter of the liquid depth, the trap is due. An inspector asks for manifests, not for a jug under the sink. A probiotic program with no pump-out record fails that inspection. If a salesperson says the bacteria make the trap legal, ask the city, not the label.
There is a narrower use that is honest. After a real pump-out, a maintenance dose is sometimes used in a long kitchen line to slow the film that grows between visits. That is a supplement. The visit is still pumping, scraping, wash-out, and a look at both pipes. GREASE.ORG sells that visit. A biological product is not on the truck as a replacement for it.
Emulsifying degreasers are a related mistake. They break grease into droplets that pass through the interceptor and reunite in the city sewer. That is worse than leaving the grease in the box, where a pumper can remove it. Hot water and a scraper, on an empty trap, beat a chemical that hides the grease until it is downstream.
Watch the video as a picture of the product category. Then schedule the pump-out on the interval the kitchen actually fills, not on the interval printed on a bottle. Fryer oil still goes in the cooking-oil caddy. Trap waste still goes out on a manifest. Those two facts do not change because a culture was added to the sink.
