Choosing between in-kitchen and underground grease traps—what would you do?

Buried traps are a nightmare when things go sideways, no argument there.

Last winter, I had to dig through half-frozen ground just to clear a clog—never again.

I hear you on the frozen-finger fiasco—been there, regretted every life choice that led me to that moment. But here’s my thing: in-kitchen traps are way easier to clean, sure, but do they ever NOT smell a little funky? I’m all for convenience, but I also like my kitchen to smell like, well, food and not last week’s stir fry grease. Anyone figured out a way to keep those things from stinking up the place, or is it just part of the deal?

Honestly, I’d take a little funk over digging around outside in the cold. I’ve got an in-kitchen trap and as long as I stay on top of cleaning it, the smell isn’t really noticeable. Maybe it’s just me, but the convenience wins out.

I get where you’re coming from—nobody’s lining up to freeze their fingers off wrestling with a frozen manhole cover at 7am. In-kitchen traps are definitely easier to access, and if you’re diligent about cleaning, you can keep the “funk” to a minimum. Still, I’ve seen more than a few folks get caught off guard when they skip a week or two and suddenly their kitchen smells like a deep fryer’s armpit.

One thing to keep in mind: those smaller, under-sink units fill up fast if you’re running a busy kitchen. If you miss even one cleaning cycle, things can get ugly quick. I once had a call where someone tried masking the smell with air fresheners—let’s just say lemon-scented grease is not an improvement.

On the flip side, underground traps are out of sight (and mostly out of nose-range), but yeah, maintenance is a pain. You need special tools, sometimes even a pump truck if it’s been neglected for too long. But they hold way more and don’t need attention nearly as often.

If you’re running solo or have a small operation, in-kitchen makes sense for convenience. Just don’t let your guard down on cleaning. For bigger places or if you’re prone to forgetting chores (no judgment—I once left my own trap for “just one more day” and regretted it), underground might be worth the hassle upfront.

Either way, there’s no magic solution—just trade-offs between convenience and capacity... and maybe how much “funk” you’re willing to tolerate before breakfast.

I hear you on the convenience, but honestly, I’d rather deal with the cold once a month than have that “deep fryer’s armpit” smell creeping into the kitchen.
