Abstract

Abstract A faucet valve comprising a removable cartridge which snaps into place, a taper-shaped insert that keys into a valve body and which fits tightly into a tapered annular ring. The lower portion of the cartridge has an external stop spanning over 90 degrees for stable stoppage of the faucet handle. The cartridge snaps together with the insert so that it can't fall out or become disengaged during assembly or normal usage. The insert has two straight projection keys which lock it into place on the valve body (i.e. prevent it from rotating on the valve body). The insert is tapered on its lower end so as to fit securely into a tapered annular ring. A locking cap secures the insert, and the pieces therein, in place vertically on the valve body.
