Anyone had problems with these? It's off the basic Milwaukee regulator/bubble ctr/needle valve setup, seems like it keeps dropping bubble rate. I set it at more than I can count, guessing 10-12 bps and within an hour it's down to like 4 or 5.....not cool. Causing BBA issues. I cleaned it out good and it seems a bit better but haven't checked it today. Regulator seems fine, holds 20 psi service side just fine, I turned it up to 30 last night to see if that will help. Just wondered if anyone else has observed this. I've read the Ideal valve is much more reliable, true? Thanks
