Thank you for the reminder. I've had terrible luck over the years with fixtures having under-lubricated parts out of the factory. In addition to almost all 8 of my bathroom faucet cartridges, my Moen shower trim handle was hard to turn since day 1 and I got Moen to send me a replacement cartridge. I think those are also pre-installed on the valve at the factory? When the handyman replaced that, I made sure he lubricated the heck out of it with the supplied silicone grease. Silky smooth now. I wrote about my kitchen faucet previously that was under-lubricated at the swivel/spout and very difficult to turn and Pfister sent me another that is better. Not as smooth as my previous kitchen faucet but that area is not user-serviceable so it'll have to do. This is now the first thing I check for when buying fixtures.pakle, this won’t fix your issue, but I and many others on here have learned to goop the heck out of cartridges, washers, screws, etc, and also the faucet or valve body, when doing a rebuild.
Not a giant glob, but give everything a thin but thorough coating.
It makes parts go in easier, maybe last longer, quieter, less corrosion, and definitely easier to yank out years later.
Plumbers’ silicone grease is your friend.
