In plumbing, a cartridge typically refers to a valve cartridge, which is a replaceable component that regulates water flow and temperature in faucets and shower valves. Cartridges are a critical part of mixing valves, controlling the ratio of hot and cold water to maintain the desired temperature. They come in various designs, including ceramic disc, compression, and ball-type cartridges, each suited for specific faucet types. When a faucet leaks or fails to regulate water temperature properly, replacing the cartridge is often the solution. Cartridges are easy to replace and maintain, making them a popular choice for homeowners and plumbers looking for quick fixes to common faucet issues.
