I just purchased a new faucet and my existing supply lines will not fit on your faucet. What can be done to correct this?

You may need to obtain an adapter in order to connect your new faucet to your pre-existing supply lines or shut-off valves. Moen faucets typically utilize either flexible supplies with ⅜" compression fittings or ½" IPS connections. Please view our Replacement Part Locator to determine your model and the connection type it uses. The size of the adapter will depend on the model and the type of fitting it needs to connect to.
