Cool that looks like our old setup. The new setup I built has a ball valve, pressure gauge, gatevalve, pressure gauge. The idea is to use the gate valve to better regulate the air, globe would be better but more pricey. Why remove the testcock? We usually just screw into it and open it. BTW two 1/4" street 90s help reduce stress on test cocks at least for the backflows in the ground
