Glass or plastic?

[AquaCrazy]

For CO2, which type of check valve would be better to use...glass or plastic? I am currently using plastic, but I found some nice glass ones online.

Should I stick with the plastic? Or try the glass ones...

I always like glass better than plastic, it's just cleaner IMO. Plastic can harbor bacteria. Really I think it's just a personal preference thing more than anything. Try it, if you don't like it, go back to the plastic.
