Well Manager pumping controls from Reid Plumbing Products LLC, of Hopewell, N.J., can get in step with a well and the connected pump so that all or any portion of a well’s production can be harvested without pumping it down. Harvesting water in this manner produces amazing results from low-yield wells. The product has been used with well yields as poor as .1 gpm to create a dependable water supply where residents previously had to haul water.
