How often do you drain your air compressor?

I have much longer drops to catch the water than this. Maybe 16 inches.
I am talking about the bottom of the loops with the drain valves. This drop will be where the water collects. It needs to be longer..

Yeah, I kinda pooched it there. Definitely need to get back to it and add more pipe above the valves, I just blow them out more often for the time being. But the temperature drop across the tubes is surprising.
