I don't recall the brand that I have on my upright 5hp compressor, but
I know that I bought it from Grainger
http://www.grainger.com/
and it works on pressure differential. When the pressure changes, it
dumps. When the unit is idle, there's no activation of the bottom
water dump. Had it for 6+ years with no problems. However, when
you're in the shop and everything is quiet....and then it "burps"....it
can
grab your attention!
