Under Sink Hookup vs. Dedicated Drain Line: Which Is Better for Dishwashers?

I’ve seen dedicated lines in new builds, but honestly, unless you’re already remodeling, it feels like overkill.

That’s a fair take. Under-sink setups have worked for decades and, as long as you keep an eye on the air gap for buildup, they’re pretty reliable. Dedicated lines are nice if you’re starting from scratch or have specific drainage issues, but for most folks, it’s not worth tearing up cabinets. Ever notice any slow draining or backup? That’s usually the main reason I’d suggest going the extra mile. Otherwise, why fix what isn’t broken?
