C02 pressure gauge just dove to zero over a week...assistance pls.

jay24k · 01/19/2007, 10:20 PM

I was having issues with my needle valve where it was constantly being clogged and having to use vinegar to clear it up. I ended up being sent a new one that I can literally blow through and it adjusts beautifully now. I've noticed in the last week I went from 500 down to 250 and now to zero. My right pressure guage is set to 20 and the c02 comes out nicely still. I'm not sure why a needle valve change would change it that drastically. Ph hasn't dropped and I use a controller. I would imagine at zero, the right guage would not be able to adjust high or lower either.

I'm going to get it refilled but I'm curious as to why. I don't see or sense a leak at all either.

Any ideas?

CO2 is sold as liquid by the pound.
When the liquid is gone, the bottle pressure drops pretty fast.

You are out of gas.

Sounds likes like a small leak from the new needle valve. I'd check the valve assembly with soapy water.

IME once the tank get to 500psi the tank is nearly empty and the psi will drop fairly fast. once my tank get a little less then 500psi i go and get in filled
