“High loops are code here too, but they’re really just the bare minimum.”
I get where you’re coming from about not cutting corners, but honestly, I’ve had an under-sink hookup with a high loop for years and never had an issue. Maybe I’ve just been lucky, but it’s been way easier to install and maintain than running a whole new drain line. For me, the hassle of tearing into walls or floors just wasn’t worth it. I guess if you’ve got old plumbing or a weird setup, dedicated might be safer, but for a lot of folks the high loop does the trick just fine.
“I’ve had an under-sink hookup with a high loop for years and never had an issue.”
Same here—my place has had the high loop setup forever, and I’ve never seen any backflow or weird smells. I get that a dedicated drain is technically “best practice,” but unless you’re already gutting the kitchen, it feels like overkill for most people. Ever actually seen a high loop fail? I’m curious if it’s just rare or if I’ve been lucky too...
Never actually seen a high loop fail either. I’ve lived in three different places with that setup and never had any issues—no smells, no water backing up, nothing. Honestly, unless you’re redoing all your plumbing anyway, it just feels like an unnecessary expense to go for the dedicated drain. Maybe if you have really old pipes or weird plumbing, but for most houses, high loop seems to get the job done just fine.
I get where you're coming from, but have you ever had to deal with a backup from a clogged disposal or sink? High loops work most of the time, but they're not foolproof. I’ve seen a few kitchens where a dedicated drain would’ve saved a lot of cleanup and headaches. Just curious—what happens if you get a nasty clog downstream?
That’s actually one of my worries—like, if there’s a clog further down the line, does it matter if the dishwasher has its own drain or not? I mean, wouldn’t everything still back up if the main pipe is blocked? I’m new to all this, so maybe I’m missing something obvious, but it seems like a dedicated drain only helps if the clog is right at the disposal or sink. Anyone ever had a backup that affected both setups?
