CO2 gauge problem

BC Mosaic · #1 10-15-2009, 02:09 AM

It seemed like the needle valve on my CO2 gauge was sticking and so I soaked it overnight in vinegar. This morning it was nice and bright and freewheeling. I reassembled the unit and fired up the system (calcium reactor)and it seemed to again not produce a steady controlled bubble stream. The CO2 tank is not empty. Is it my solenoid then that is faulty? How do I check? Either item is pricey.
Thanks

You can buy new seals and repair it yourself or get it professionally rebuilt for a reasonable price at a welding or beverage supply company.

IF the solenoid is faulty you would hear it clicking on and off ...... I'd bet it's the needle valve

If it is just a guage go to princess auto and get one. You should not have to wash a gauge. I think it is your needle valve.

Thanks guys.

The solenoid is not clicking so it then must be the needle valve but if I open the neddle valve completely then I still don't get any bubbles for a bit and then a whole whack of streaming bubbles.

Fencer,
I soaked the needle valve and not the gauges themselves.

I've had this unit (Milwaukee) for 3 years, bought used for $120.00.

Mr. Wilson
Thanks for the info but it will probably be cheaper buying a new/used unit than getting it professionally fixed (?)

The seat and disc can get worn fairly easy in a needle valve, especially if the alot of pressure is put on them. (eg- the valve is closed very tightly) Normally a needle valve has very fine throttling, as soon as the seat gets worn that ability is gone. HTH,
