Description Frostpro is a device that fits Topaz and Vortex Valves to minimize freezing in cold weather conditions. It is manually operated and when turned on allows a continuous flow of water through the valve to assist in the prevention of water freezing in the valve and pipe work supplying it. • Freeze prevention device for Topaz and Vortex Float Valves. When temperatures approach freezing FROSTPRO cap is turned clockwise by hand to activate it. A low flow of water passes through the valve to prevent valve and pipelines freezing. The continuous flow into tank may be counteracted by lowering water level with the extension arm thereby minimizing spillage through tank overflow pipe. When temperatures are above freezing FROSTPRO can be turned off by hand and the extension arm can be retracted. FROSTPRO is effective when temperature rises above freezing for a few hours each day. Its effectiveness varies depending on the positioning and insulation of water storage tanks and pipelines.
