Moen.com provides manuals for Moen shower faucets. Click the Parts & Support tab and enter the model number to find the correct manual for your shower faucet.
The Parts & Support tab also provides specification sheets, installation instructions, parts diagrams and replacement parts. If you do not know the model number, provide as much information as you can on Moen's Replacement Parts page, such as the room the faucet is in, the type of finish and the number of handles. The site narrows down the choices and presents pictures of models that fit the criteria. Once you click on your faucet, an exploded view diagram with part names and numbers appears.
