Can anyone tell me how to adjust the pressure relief valves on top of my bright tanks? Mine are blowing off at very low pressure, causing me to waste alot of CO2.

DEPENDS ON THE MANUFACTURER. SOME HAVE ADJUSTMENT SCREWS, SOME ARE CONTROLLED BY SPRINGS. NEXT TIME YOU ARE EMPTY, PULL IT OFF AND LOOK AT IT. THIS SHOULD BE DONE ROUTINELY ANYWAYS TO CLEAN IT. YOU NEED TO ALSO ADAPT THE PRV TO A CO2 SOURCE SO YOU CAN TEST IT WHEN YOU ADJUST IT. DO NOT ADJUST WITHOUT TESTING! IF YOUR PRV HAS A SPRING AND NOT A SCREW, YOU CAN EITHER CALL THE MANUFACTURER AND GET A NEW SPRING, OR GO TO A HARDWARE STORE AND GET SOME WASHERS(SHOULD BE STAINLESS OR TEFLON) THAT CAN BE PUT NEXT TO THE EXISTING SPRING TO INCREASE THE FORCE OF THE SPRING THUS INCREASING THE PRESSURE NEEDED TO BLOW OFF. WHATEVER YOU DO MAKE SURE YOUR TANKS ARE RATED FOR THE PRESSURE AND THAT THE PRV WILL RELEASE AT YOUR GIVEN REQUIREMENT.
HOPE THIS HELPS.

But remember...it is against the law to pressurize non
ASME rated tanks above 14.7 PSI
