If you get tired of your trap fill up, you can get one automatically
drains now at Grainger. I installed one two years ago, and haven't seen
water in my 10 HP system since.

Yes, I left that detail out. If you put a 1/4" petcock on the bottom of my
big diameter water condensing trap, you can leave it open, just a tiny, tiny
amount. Not so much you can even hear any air hissing, but it will be
enough to let the water out, unless you are really running the compressor(s)
hard, for a long time.
