Cartridge faucets operate with a movable stem cartridge that moves up and down to regulate flow. They are identifiable more by how they feel when they operate than how they look. As opposed to a ball faucet that you push back to turn on, a single handle cartridge faucets operate in an "up/down" motion to adjust water volume and a "left/right" motion for temperature.
Similarly, a two handle stem cartridge faucet looks almost indistinguishable from a compression type washer faucet. However, again, you can tell the difference by how the handles feel when used. A compression faucet requires you to tighten down (compress) the washer to close the water flow. With a cartridge faucet, the action is smooth and consistent. When the handle gets to the off position, the faucet turn off without added pressure being required as with a compression faucet.
Handle Type: Single or Double
