Abstract
A water control valve has a plurality of ports and a mixing chamber and a removable cartridge in the chamber for controlling water flow. A flushing plug is receivable in the chamber in place of the cartridge for enabling flushing and pressure testing of the ports. A retainer removably holds either the cartridge or the flushing plug in the chamber. A method of pressure testing and/or flushing a water control system includes the steps of removing a clip that holds a mixing cartridge in a valve body; removing the mixing cartridge from an opening in the valve body; inserting a flushing plug into the opening in the valve body; and replacing the clip to hold the plug in the opening in the valve body.
