WINTER VALVE 32 PEM IN THE PIPE

Winter installation valve for "frost-free installation." Used when the pipe cannot be placed below the frost line. Requires that the pressure pipe slopes evenly from the point of use toward the well. A specially designed air vent valve and check valve must be installed before the pressure tank. When the pump stops, the water in the pressure pipe flows back into the well, automatically emptying the pipe. When the pump restarts, the air in the pipe is first expelled through the air vent valve, and when water reaches the air vent valve, it automatically closes, allowing water to flow into the pressure tank.
