Watch Guard Float Valve Systems

Watch Guard is the reservoir-mounted float valve system designed to cut service and maintenance costs. Watch Guard delivers reliable water valve activation every time with superior features for greater reliability. The float is filled with water-soluble material instead of the standard system-clogging sand. The 90° chemical barb rotates 180° to ensure the chemical pick-up tube does not kink. Metering tips screw in, ensuring proper installation and no damage during maintenance. Several different models are available for different fill rates and chemical induction.
