Re: Valve for CO2

Hoa:  I bought an all plastic valve at my local aquarium store for
$1.50 or so, works fine and no sign of deterioration.  And it is
checked every time it is used (twice daily, don't ask, it's a long
story).  And it works every time.  No visible deterioration in six
months, nor is there any reason a weak acid like carbonic should
attack a plastic valve.    Dave
