LPT: If you have a broken faucet (and basic mechanical skills), you can get FREE faucet replacement parts by calling the manufacturer's customer service.
I called Delta they said the faucets they sell at big box stores and plumbing stores are identical but why do seemingly all plumbers say they are not?
Replacement parts for old Delta water faucet
Replaced seats, springs, cartridges in delta faucet 3 weeks ago & it’s been working fine until tonight, cold water started to leak from the faucet, then started flowing out nonstop. Replaced the seat and now it works perfect. What caused the new seat to get this tear, did I do something to cause it?

I have a Delta faucet with a corroding metal piece that holds the sprayer. I called their customer service (long long hold time, be prepared), described the problem to a very nice lady, she identified the part assembly that would fix it, and I'll have it in hand in two weeks for free. I had my original purchase receipt (from 4 years ago), but they didn't need a copy. I've done this with other faucet companies also; this one tiny rubber gasket that controlled the sprayer failed about four times in 10 years, and they sent a new piece every time. Terrible design but good customer service.
I asked do their faucets at big box stores have more plastic parts vs plumbing stores and was told no they are identical, I asked if I examined them internally and everything would they be, the answer was yes, I even spoke with a manager. But why is it every plumber I've ever heard of recommends the plumbing store because they have more metal parts? 🤔
