Turn the pump off and open a tap to release the pressure in the
system. The pressure in the accumulator should be just over 20 psi,
so that the accumulator makes the most contribution to the flow of
water before the pump cuts in.
Then close the tap and turn the pump on. When it stops the pressure
in the accumulator should be 40 psi.
All the best

Go steady, but keep going.
