Finally got my kitchen faucet drip sorted after 6 tries...
So I've been fighting this slow drip from my kitchen faucet for about 3 months now. I kept thinking it was just a bad washer, replaced that twice, then the O-ring, nothing helped. Last weekend I finally sat down and watched a YouTube video from a guy in Ohio who does step by step tear downs. Turns out the cartridge had a tiny hairline crack that you could barely see unless you held it up to light. After 6 trips to the hardware store and about 8 total hours of messing around under the sink, I swapped that cartridge and the drip stopped immediately. I felt like a total idiot for not checking that first, but hey, it's done now. Has anyone else dealt with a crack that was basically invisible until you pulled the whole thing apart?
