Valve manufacturer Flomatic has rollout out its new Drain-Back Plug, Model 48, for submersible pump water well installations.

In a release, the company says the reusable Model 48 is designed to drain the riser pipe. It activates when a weight drops into the well drop pipe. The plunger is stroked by the weight and opens the valve, which returns to its closed position when the drop weight is removed. The Model 48 is NSF 372-certified, and designed in all stainless steel construction with Buna-N resilient seating.

Flomatic says the Model 48 can be easily replaced in the field, helps eliminate water splashing at the surface and prevents potential cross-contamination of the water well. The spring-loaded valve threads into a 1-inch pipe tee. The company says using the Drain-Back valve reduces pulling weight from 20 to 50%, making it easier to pull pipe and pump.

Flomatic, based in in Glens Falls, N.Y., manufactures a range of valves for domestic and municipal water and wastewater applications. Flomatic is ISO 9001 and 14001 certified, with AIS-compliant products. For more information, visit, email, call 800-833-2040 or fax 800-314-3155.
