[VAC] Re: Accumulator Tanks

[Jim Dunmyer <jdunmyer@xxxxxxxxxxx>]

Harvey,
 The accumulator that I used has a bladder in it, so should never need
air.

My reason for changing the pump and adding the accumulator was that the
Jabsco diaphragm pump was laboring when it approached shutoff, sometimes
even making the switch click on and  off with the pulsations. In
retrospect, the pump was probably acting normally, but the water heater
had become waterlogged after a few weeks' use. This is normal, of
course, but before all the air disappeared, it acted as an
accumlator/air cushion so that the pump would come up to pressure and
STOP. All that was probably needed was the accumlator, not a new pump.
