Why would you need to adjust it at all? Your pressure switch is what sets the pressure in the system, and you appear not to be replacing that. Isn't the accumulator is just the pneumatic equivalent of a spring? AIUI, all you need to do is ensure that the tank will accept a higher pressure than the switch is set to. Adrian .
