I was searching the band VOLA when I came across the faucet brand that makes very expensive but very repairable, and that compelled me to finally ask. I’ve replaced a few faucets over the years that were at the end of their life, but the last one took to a plumbing supply to get what looked like an obvious replacement part and they said it’s some home depot brand that doesn’t make them.

Thanks for the info, I’ve never thought to buy old since over only ever replaced cheap and only faucets, but when it comes time to work on my kitchen I’ll check out the brands you mentioned.
