I hear you, but I’ve seen a slow drip under a sink turn into a full-on cabinet rot more than once. Even with good brackets and trays, water finds a way if something goes wrong. I get not wanting to gut the kitchen, but if you’ve got old plumbing or any weird smells, I’d at least do a thorough check every few months. One client thought their setup was fine—until the bottom of the cabinet caved in from hidden water damage. Sometimes it’s just luck, but sometimes it’s worth being extra cautious.
I totally get where you’re coming from about hidden leaks—seen a few gnarly ones myself. Even a tiny drip can sneak up on you and do way more damage than you’d expect. When it comes to dishwashers, I lean toward a dedicated drain line if you’ve got the option. It’s just one less thing sharing space under the sink, and you’re less likely to get those weird backups or slow leaks that can go unnoticed for ages.
If you’re sticking with the under-sink hookup, I’d suggest checking the connections every couple months. Run your hand along the hoses and joints to feel for moisture, and keep an eye out for any discoloration or soft spots in the cabinet base. I’ve seen folks put a water alarm under there too—cheap insurance if you ask me.
But yeah, if your plumbing’s old or you’re smelling anything funky, it’s worth pulling everything out and giving it a good look. Sometimes it’s just a loose clamp or a bit of corrosion, but catching it early saves a ton of hassle down the road.
Couldn’t agree more about the water alarm—saved me from a nasty mess once.
Dedicated drain lines are cleaner, but honestly, most folks just don’t bother unless they’re already redoing plumbing. Either way, regular checks are a must. I’ve seen too many cabinets rotted out from slow leaks that went unnoticed for months.“Even a tiny drip can sneak up on you and do way more damage than you’d expect.”
I hear you on the slow leaks—nothing like opening a cabinet and finding that lovely warped wood smell. But here’s my thing: is a dedicated drain really worth the hassle if you’re not gutting the kitchen anyway? I’ve seen plenty of “quick fixes” turn into bigger headaches down the line. Water alarms are great, but how many tenants actually pay attention to them? Just makes me wonder if we’re overcomplicating something that could be solved with a flashlight and five minutes every month...
Honestly, I get where you're coming from—sometimes the “fix” is more work than the problem. But man, I’ve seen those under-sink hookups back up and flood faster than you can say “call a plumber.” Dedicated drain lines aren’t always necessary, but they do cut down on those midnight emergencies... just depends how much chaos you’re willing to risk, I guess.
