ABSTRACT:
A diverter valve includes a housing and a diverting stem cartridge. The housing has a top and a bottom and a stem cartridge receiving chamber. The housing also has an inlet port proximate the bottom thereof and a plurality of laterally directed outlet ports. Each outlet port directs water to selective alternative uses such as a spout, shower, body spray or the like. The stem cartridge also has an inlet port proximate the bottom and has a plurality of laterally directed outlet ports for selective alignment with the outlet ports of the housing. The inlet ports and outlet ports of said stem cartridge has there-between a stem waterway to allow water to flow from the inlet to said outlets. The cartridge has contained therein at least two checking mechanisms disposed prior to the waterway. The at least two check mechanisms prevents water from the outlet ports from contaminating the water supply. Replacement of the stem cartridge permits simple replacement of faulty checking devices without the need for skilled tradesmen being involved.
