Little Giant 1/2 HP Shallow Well Pump
I bought this pump to replace a Sears Hydro-Glass model that I had installed in 1979. This month, after 33 totally trouble free years, the pump housing cracked but the motor was running fine. I chose the Little Giant pump because it has an AO Smith motor, same as the Sears, and a Square D pressure switch, both good products in my estimation. Also, I have a Little Giant sump pump and a condensate pump and they have worked without incident. I don't know what the service life will be on the Little Giant but, then again, I won't need 33 years. The L.G. pump body is cast iron while the Sears is fiberglass with a much bigger housing. The pump runs as expected although I am not sure if it matches the Sears, especially when it was newer, gallons per minute rate. But, the little Giant is sufficient to satisfy the needs of the two people in my household and if we have a problem with it I will not be too shy to report same.
