If you don't increase the charge pressure the water will squeeze the bladder down so small you will have almost all fluid in the accumulator and no gas in the bladder to help it hold pressure as the fluid is released.
Shurflo may have a data sheet for that accumulator on their web site but I would have to look around for it.

Thanks, I didn?t check the pdf file yet, but from what I understood the accumulator has maximum operating pressure of 125psi, so I will charge it to 110psi and than set pump demand off to 130 and turn on to 110psi. (pump is adjustable between 120 and 140 to turn off)
