That's an interesting feature and I am sure helpful. I wonder though about my situation with running one diffuser and how effective that makes it. Maybe I am running to much compressor for what I need.
In the end as long as I know it is working right and does what it's supposed to then it is all good.
Never knew this would get so complex

Now I just need a simple 1/2" check valve at my compressor output. The one I hooked up tonight chattered bad. A Milwaukee Valve .5psi crack pressure.
Suggestions for a check valve. This one should be simple I hope.
