Abstract

A plumbing fixture has a housing defining a chamber and having a bottom wall forming an upper surface and formed with at least one inlet port opening at the upper surface. A cartridge assembly in the chamber having a bottom surface directly confronting the bottom-wall upper surface is formed with an inlet port opening on the bottom surface in line with the bottom-wall inlet port. An inlet conduit having an end fitting extending through the inlet port and into the inlet port is formed with an outwardly open circumferential groove generally level with the surfaces. A split and spreadable snap ring fitted to the groove bears on the floor. One of the ports closely surrounds the snap ring and prevents it from spreading and a seal ring engages around the end fitting in the inlet port of the cartridge assembly.
