CO2 Tank Regulator Question

[spiderman097]

I have a CO2 tank, and the meter for the head unit slowly goes down as CO2 is consumed. Is there a leak in my regulator? The solenoid is working fine. Here's a picture.

get some soapy water and spread it around all the joints and see if there is a leak. Might be as easy as just unscrewing something and adding some teflon tape. If its a guage or a crack you might have to replace the whole thing.

Mine had a bad guage and a bad solenoid and it was cheaper to just get a whole new unit.

I'm confused... what meter are you talking about?

one gauge is supposed to tell you tank pressure (volume of CO2) and the other is supposed to tell you the pressure at which CO2 is being delivered to your bubble trap..

?
as the tank pressure lowers, so too can the pressure setting for the output line.


.. use soapy water and a toothbrush around all the connections.. if it bubbles, there's a leak..

fwiw, I replaced the gauges in my regulator for less than $30


BEAT ME TO IT.. (soap always works for air leaks)

it's the pressure at which CO2 is being delivered to my bubble trap

What you have is called a single stage, dual gauge regulator. From the pic, like Ron said, the right gauge is the CO2 cylinder pressure, and the left gauge is the baseline pressure at which CO2 is being delivered to the bubble counter or wherever. There should be a minimum pressure that this never goes below, like maybe 5-6 PSI. What you will see is that the left side gauge can rise when the regulator solenoid is off, then after the solenoid is energized it goes down to the baseline PSI reading (5-6).

The baseline delivery PSI is set by rotating that rusted slotted center screw at the bottom of the pic in the center of the "UNIWELD" logo clockwise to increase the baseline PSI or counterclockwise to decrease it. But the true baseline delivery PSI will be seen when the solenoid is energized and has been on long enough to lower the pressure to the baseline delivery pressure rate.
