The Jobe Valve Frostpro is a device that fits Topaz and Vortez 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 waterline supplying it.

PRINCIPLE OF OPERATION

When temperatures approach freezing the Frostpro cap is turned clockwise by hand to activate it. A low flow of water passes through the valve to prevent the valve and waterlines from freezing.

The constant flow into the tank may be counteracted by lowering the water level with the extension arm which will minimize spillage through the water tank overflow pipe.

Once the temperatures are above freezing, Frostpro can be turned off by hand and the extension arm can be retracted.

EFFECTIVENESS

The Frostpro is most effective when the temperatures rise above freezing for a few hours each day. Its effectiveness varies depending on the positioning and insulation of water storage tanks and pipeline.
