Star Water Systems 4H10A05005 Submersible Well Pump

Product Description

The STAR WATER SYSTEMS 4H10A05005 is a 1/2 HP submersible well pump built for residential water supply applications. Rated at 10 GPM, it delivers consistent flow from various water level depths to the well head. The pump, motor shell, and drive shaft are constructed from 4-inch diameter stainless steel for corrosion resistance and long service life. Operating on 115 volts single-phase power, it is designed for quiet, economical operation. Manufactured by Flint Walling, the unit uses a water-lubricated Franklin motor, a contractor-recognized standard in the well pump industry. The package includes heat-shrink splice kits and illustrated installation instructions.

This pump is sized for the average residential home and family, where 10 GPM capacity meets typical household demand. It is installed in 4-inch or larger well casings and suits standard single-family residential water systems. The cast-iron discharge fitting and built-in lightning protection add durability and electrical safety in field conditions. Licensed well pump contractors and plumbers routinely specify this unit for new installations and direct replacements in residential drilled wells.

Installation Notes

Installation should be performed by a licensed well pump contractor or plumber in accordance with applicable local codes and the manufacturer's illustrated instructions included in the package.
