cerich:Those with the noise issues, look at the inlet were the DVT is, is the plastic there white? If yes then we have the solution ( I've posted here before on it), if it's red then please PM me so we can get this looked at. Either way PM me and we'll get it resolved.
Best,
Chris
PS- There is no and has not been a recall on Delta 4 regulators....
Mine is red from day one.
