GLENS FALLS, NY (June 2022) – Flomatic Valves is proud to introduce the patented Model 48 Drain Back Valve® available in a 1-inch size for submersible pump water well installations. Flomatic’s Model 48 Drain Back Valve® is constructed with corrosion resistant stainless steel body and plunger, and features NSF 372 low lead approval.
The NSF 372 certified Model 48 Drain Back Valve® is designed to reduce pulling weight by 20% to 50% and eliminate water splashing at the wellhead. The valve is built to automatically drain the riser pipe and is activated when a Drop Weight® (4801DW1), is lowered into the well riser pipe. The spring-loaded plunger is activated by the weight – opening the valve – which returns to a closed position when the drop weight is removed. The Model 48 Drain Back Valve® automatically resets after each use.
