This is a brand new taprite regulator. I tested all connections and no leak what so ever. My c02 tank would be empty for sure if it was a leak. I have no idea if its leaking inside the diaphram. My old one sounded the same to Me. I'm assuming the new one is fine. I put bubbles everywhere. Also if it was a leak the sound would continue but this goes away in a couple minutes.
So I just got a new tap rite regulator hooked it up tested for leaks. Nothing at all. Problem is this...if I out my ear up really close to the regulator I can hear the tank running gas still. Even minutes later. Sounds like a tiny leak but I'm positive its not. Anyone ever heard of this before?
