It isn't. If you were using the pump to pump water to garden sprinklers
one of the other pumps would work ok. Since he want's to wash the car,
you have the issue of the hose nozzle shutting off while he soaps the
car and the other pumps won't handle this condition well and can
overheat. With the well pump setup the pump shuts off when it fills the
accumulator tank to pressure and will restart smoothly as the
accumulator provides the initial flow when you turn on the nozzle again.
