I have a "Chateau" model Moen tub faucet that was replaced. What is a fair price to pay for this service and how does a person know if the cartridge needs replacing instead of just the "O" ring? I paid $231.00 and think that price is too much. Several years ago I also had to replace a kitchen faucet cartridge and a tub/shower faucet cartridge. My house is 11 years old. Shouldn't faucet cartridges last longer than that? Thanks.
