We bought this home in March 2019 and previous owner installed new sink and had this Moen model for likely less than 5 years. It was leaking but loved the design so much bought exact same model 6/4/19. I could not remove the handle to check gaskets due to previous owner damage to "L" wrench socket. Checked with suppliers of this product who said no warranty coverage without paperwork. Disappointed, then to find broken Deck Gasket, Part B perhaps the cause of leak. You could redeem yourself by sending a replacement gasket along to us - it may render old faucet redeemable to someone, or backup for our use someplace/some time? Wife was hesitant to buy same model because of her concern for longevity.
