"After replacing mine, haven't had to crawl under there with a flashlight once—my knees thank me daily."
Haha, I feel this. But speaking of reliability, has anyone thought about the safety angle? Like, ceramic discs are great and all, but I've always wondered if there's a proper way to check them periodically for wear or cracks. I mean, they're sturdy, sure, but nothing lasts forever... Wouldn't hurt to know how to spot early signs of trouble before it becomes another midnight adventure under the sink.

Good point—I usually just listen for changes in how smoothly the handle turns or if it starts feeling gritty. But is there an actual visual inspection method that's reliable?
I've wondered about this myself, actually. A couple years back, I had a faucet that started feeling gritty and stiff when turning the handle, just like you described. At first, I thought it was just mineral buildup or something minor, but when I finally took it apart, I found one of the ceramic discs had a hairline crack running right through it. It wasn't leaking yet, but clearly it was on borrowed time.
From what I've learned since then, visual inspection is definitely possible, but you have to be careful. Ceramic discs are pretty delicate, and sometimes cracks can be really subtle—almost invisible unless you're looking closely under good lighting. What I usually do now is remove the cartridge carefully (after shutting off the water, obviously), clean it gently with a soft cloth, and then inspect it under bright light. Holding it up against a flashlight or lamp can help reveal tiny cracks or chips that might otherwise go unnoticed.
Another thing I've noticed is discoloration or uneven wear patterns on the discs themselves. If you see dark streaks or rough patches, that's usually a sign they're starting to degrade. It's not always a guarantee they'll fail soon, but it's a good indicator that you might want to keep an eye on them or even replace them proactively.
One plumber friend of mine suggested lightly running your fingernail across the disc surface—if you feel any catching or roughness, that's another clue something's off. Just be gentle, because ceramic can chip easily if you're too rough.
Honestly, though, I think your method of paying attention to how the faucet feels when turning is probably the most practical day-to-day approach. Visual inspections are helpful, but realistically, most people aren't going to dismantle their faucets regularly unless there's already a noticeable issue. Still, it's good to know what to look for when you do get around to checking them out.

Totally agree with this. Most people aren't going to dismantle their faucets regularly, so noticing subtle changes in how it feels is key. I've found that being proactive about these small signs can save a lot of water (and headaches) down the line. Good on you for taking the time to inspect and share your findings—it's helpful info for anyone trying to maintain their fixtures sustainably.
Yeah, I've noticed that too. Last year, my kitchen faucet started feeling a little gritty when turning—ignored it at first, but ended up with a leak underneath the sink. Definitely learned my lesson about paying attention to those subtle signs...
