Star Water Systems 4H10A07305 Submersible Well Pump

Product Description

The STAR WATER SYSTEMS 4H10A07305 is a 4-inch diameter submersible well pump rated at 3/4 HP and 10 GPM, designed for residential water supply systems. The pump body, motor shell, and drive shaft are constructed from stainless steel, supporting long-term submersion in well environments. It operates on 230V, 2-wire configuration and uses a water-lubricated Franklin motor, a standard recognized by well pump contractors across the trade. Cast-iron discharge hardware and built-in lightning protection are included. Heat-shrink splice kits and illustrated installation instructions ship in the package, supporting a clean field installation.

This pump is sized for the average residential home and family, targeting systems that require up to 10 GPM delivery to the well head across varying water level depths. The 4-inch diameter housing fits standard 4-inch well casings commonly found in residential construction. It is manufactured by Flint Walling under the Star Water Systems brand and is suited for new installations or direct replacement of similarly rated submersible well pumps in single-family residential applications.

Installation Notes

Installation of submersible well pumps should be performed by a licensed pump contractor or plumber familiar with local well codes and applicable IPC requirements. Disconnect and lock out all electrical power before handling pump wiring or splicing connections. Use the included heat-shrink splice kits to maintain watertight wire connections at the splice point. Do not run the pump dry, as the Franklin motor relies on water for lubrication and cooling.
