Watch Guard
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. And metering tips screw in, ensuring proper installation and no damage during maintenance. A number of different models are available for different fill rates and chemical induction.
