I've had a few CO2 tanks go too quickly and I think I've narrowed it down to my secondary regulator. I have a Taprite 4-way and I believe the model is T1694ST. If I turn off all four of the shut-off valves on the secondary regulator and turn off the one on the primary regulator (also Taprite), wait a bit, and then open the shut-off valve on the primary I hear it re-pressurize the secondary.
The #4 regulator on my secondary I believe to be faulty. It believe it doesn't seal correctly so the pressure will increase over time to well past what it is set to (I learned this by over-carbing a keg a while back.) That shut-off valve has remained closed since, but I've been experimenting a bit and it is currently reading about 25 psi. The #1 and #3 regulators are both set to roughly 16 psi and I have been using them with no issues to serve kegs of beer (yeah, that's a little high for beer, I'm testing slightly different pressures.) The #2 regulator I use to make soda water, so it is set to around 36 psi.
I originally suspected my soda water setup to be the culprit, so I've always left that check valve closed unless I'm making soda water. All that setup is is a short gas line leading to a gas ball-lock quick-disconnect that I can connect to a carbonation cap. This might leak too since I hear the line re-pressurize when I turn on the shut-off valve, but that shouldn't be a significant source of CO2 loss since I never have that shut-off valve open for more than about 30 seconds at a time, I wouldn't think.
Here is where I get a bit confused. I have noticed is that when I shut everything off the pressure for the #2 regulator (soda) will slowly drop over time to match that of the #4 regulator (faulty). It has done this for two different settings on the #4 regulator so it doesn't seem to be a coincidence. The #1 and #3 pressures are never affected, though I haven't tried to set the #4 pressure below 16 psi yet.
Any thoughts? Sorry for the long post but any help will definitely be appreciated. Thanks.
