Is there an easy way to used compressed air to pressure test a keg instead of CO2? Really don’t want to waste CO2 to check kegs. I have one I started with that seems ok pressurized with CO2 and sprayed with Star San for leaks.
Bought two more that came pressurized but had old nasty p rings. Disassembled to replace o rings and soak parts. Pressure tested them and one of the PRV leaking. The plastic on the valve had been smashed. Thought I pressured them up the other day I pulled the PRV’s and both were empty. Not sure if I vented them or not though. Think I set them to 20 psi.
Anyways don’t want to waste any more CO2. Seems like so sort of fitting to connector to air male air line fitting with ball valve would work to pressurize them. Maybe an inline pressure guage.
