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

I’ve seen too many surprises with underground units - roots, shifting soil, even a cracked lid once that nobody noticed until it was a disaster. Regular pumping helps, but you’re still pretty much blind until there’s a problem. In-kitchen traps might be messier, but at least you know what’s going on. Guess it depends on how much hassle you’re willing to risk down the line.

Honestly, I’ve seen both setups go sideways for different reasons. Underground ones are out of sight, but when something goes wrong, it’s usually a big deal and not cheap to fix. In-kitchen traps are way easier to check, but you’re dealing with the smell and cleaning more often. Have you ever had a backup with an in-kitchen unit? Curious if the hassle is really any less when things go south.

Had one clog up once - grease got thick fast and overflowed under the sink. Yeah, it was easier to spot and clean, but man, the smell lingered for days. Honestly, neither option is totally hassle-free. Just feels safer being able to check it often, though.

I get the appeal of being able to check the in-kitchen trap, but honestly, I’m not convinced it’s less hassle. Had a friend with one - she was constantly cleaning it out, and the smell was brutal if she missed even a day. I’d rather deal with an underground unit and just schedule regular cleanouts. Out of sight, out of mind... and out of nose, hopefully.

I hear you on the smell issue - my neighbor had a similar problem with their in-kitchen trap, and it definitely wasn’t pleasant. But I do worry about underground units too, especially if there’s ever a leak or overflow you don’t catch right away. Have you found any good ways to monitor those without digging things up? I’m always a bit paranoid about hidden maintenance problems causing bigger headaches down the line...
