ADA CO2 Check Valve
The ADA CO2 check valve may look like other low quality check valves- but it is not. It is mandatory to change out your CO2 check valve annually; as CO2 degenerates the valves. It is much less expensive to replace a $7 check valve than replace a CO2 regulator or solenoid.
The ADA check valve should be placed after the ADA Hi-Pressure tubing to the ADA low pressure tubing then to the bubble counter.
