A cartridge is the heart of any faucet and the single-most important component in terms of a faucet’s overall performance. This small part has a huge responsibility: Controlling flow and mix of the incoming water. Over time, rubber O-rings and other internal parts can wear out. A cartridge has a standard lifespan of five to ten years and can be replaced or serviced on a preventive basis. However, not all cartridges are created equal, so understanding what you want your cartridge to achieve will guide you towards the best purchasing decision and ultimately the best performance experience.

Ceramic Disc Construction with Integrated Check Valve Cartridges (XKC) for Food and Beverage Industry

Cross-flow in faucets happens when the pressure in the hot and cold water lines varies. For applications where a valve is downstream – like pre-rinse faucets or service sink faucets – a check valve is critical. Cross-flow can result in higher energy bills for the facility, poor temperature mixing, and create a breeding ground for bacteria. 

Application: These cartridges­ are ideal for food service and janitorial applications. You can find it in our most popular food and janitorial products. They are also an energy saving addition to low-flow faucets, which are at a greater risk of cross-flow.  

Key Features and Benefits:

  • Integrated check valve to prevent cross-flow, eliminates need for separate check valves in challenging applications like janitorial sinks
  • Commercial grade ceramic cartridge design with a solid brass sleeve for durability and long life
  • Fit most Chicago Faucets products with short-stem handles
