160657 Cartridge: Kitchen Faucet

The 160657 water flow cartridge is built directly below the faucet handle and controls both volume and temperature. It is commonly used in Moen single handle faucets produced after 2012 (date varies based on style and model).



  • The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet.
  • Recommended Tools: Pliers
  • The following instructions assume the handle and associated handle pieces have been removed. For additional details, visit and select the type you are repairing. The faucet guide will contain specific information on handle assemblies associated with that style of product.

    Moen manufactures many types of faucets that use the 160657 cartridge. The different faucet categories are based on where the on/off handle is located. Refer to the images below based on your handle location.
