Paintball CO2 Relief Valve leaking

[TCC]

I have a 20oz paintball canister I use for carbing root beer. I have a high and low pressure gauge regulator with some tubing and an air chuck (I have valve stem carb caps). When I screw on the regulator (using the paintball adapter) everything is fine. I can charge a bottle or two with no problems. After a few seconds or so the relief valve on the paintball canister will start to release co2. The only way I can get this to stop is unscrew the regulator.

Is there something I am doing or not doing? Do I have a bad relief valve? (the canister is new)

Thanks for any advise.

Those paintball tank relief valves open at about 25-30 psi so it shouldn't leak if you stay below its threshold. You could also re-set the valve to a higher pressure.

Thanks. I have stayed under 25 psi. The relief valve starts to discharge gas shortly after I screw on the regulator even without using any gas.

I guess I can have them check it when I go get gas.
