Mach 5 Headhunter water pump

[TechTalk]

We suspect that a pressure switch may be out of adjustment or some other similar problem. We have found the 120 volt Headhunter pump (run through the inverter) to be far superior to the typical 12 volt RV water pumps. The reliability of the 12 volt pumps was always a problem, with short time failures common if the pumps were used for high volume applications, such as to fill a clothes washer or bathtub. In addition, the Headhunter pumps are designed to be used full time. This includes while connected to shore water, when the Headhunter pump acts to increase or decrease water pressure to the set point. Irratic water pressure complaints are not typical with the Headhunter pumps, and therefore we suspect a problem that can be fixed.
