The Moen website home page features a section called "Replacement Parts" that can be used to look up model numbers for the kitchen and bathroom faucets in their product line. A "Use our alternate search" link, which will lead to a model number look-up page, can be found following the text "Don't have the model number?"
The "Use our alternate search" link opens a page that enables the visitor to choose either "Bathroom" or "Kitchen" for the fixture they are looking for. After selecting one of the two options, the "Continue" button leads to additional options that specify the product finish, the number of handles and whether there is a side spray. After making those choices, the next "Continue" button brings up a picture of the fixture and displays the item's model number.
