I have Moen faucets through out the house, all are original, twenty years old. They have the brass cartridge, that I like because it only takes 20 minutes to pullout, clean, and new "O" rings. So I want to keep that brand. I've bought three kitchen faucets, going to have to buy the fourth one. The original was deeply scratched, and the builder, not the plumber replaced it. Are there different grades to these faucets? Are the ones at the big box stores just made cheaply? Any recommendation on a new Moen? Rest of house is fitted with the Chateau models.
