I am a dealer for Taprite regulators. I am not sure who you purchased this from, but Taprite is very good about standing behind their regulators. Call me tomorrow and I will help you with this. You did not have to purchase it from us for help. You can email me at firstname.lastname@example.org
or call me at 325-356-5204. We might be able to troubleshoot this and figure out the issue over the phone. I am assuming you already tried to turn up the regulator and that did not work. It almost sounds like a stuck check valve, but that is just a guess. Can you send me a photo of the regulator so I can determine which one it is?
