The faucet in the bathroom has been leaking for months and finally today I disconnected the water lines and removed it. Fortunately Home Depot is still carrying the part of a 17-year old Moen faucet! The picture is the Moen 1224 replacement cartridge inside the faucet. The hard part was crawling under the lavabo, laid on my back and tried to work in the confined space. Not fun but I got to play plumber.
