If your Cornelius regulator leaks from the little weep hole on the face, and it does so only when you reduce your output pressure setting, then it might be comforting for you to know that this is normal behavior. Unlike other regulator brands the Cornelius will immediately release the excess pressure on the output side. After being told both here and at my LHBS that my regulator was bad, I decided to ask the manufacturer. The email exchange is included below ...
=============================================
What your regulator is doing is normal.
I would suggest if you have to lower your output pressure you should
back the regulator down then purge some gas from the out put line this
will allow your regulator to reset to the set pressure.
I would actually set the pressure lower than what you want, purge the
output then raise the set to the desired pressures.

Hello,
I have a cornelius regulator that either works differently from many other brands, or is faulty. I'm hoping you can tell me which is the case.
In the following experiment I start by soaping up all the fittings, including the regulator body. I crank the output pressure to 20-30.
Any leaks? No.
I then crank the OP down to 10-15. The OP gauge backs off immediately,
which is different than many other regulators. Back pressure is then relieved through the small weep hole in the face of the housing, where I
get a soap bubble. If I then crank the output P back up, the soap bubble
actually shrinks.
Is this normal behavior for your regulators, or do I have a faulty one?
My concern is whether I can safely back off the output pressure when the
CO2 tank is open, as I recently lost most of a CO2 tank this way. Perhaps the back pressure relief got stuck open? I have installed a rebuild kit since then, but it still releases pressure whenever I reduce the OP setting.
Others have told me the regulator is bad, but I'm thinking that perhaps this behavior might be by design?
Thank you for any assistance you can render.
