Best check valve for calcium reactor?

[Breakin Newz]

What are the best check valves out for calcium reactors? I've used a few and they seem to fail on me! Suggestions/experiences would be great!

I've use this - "THE BEST" Check Valve (medical grade)

It has a very low crack pressure (CRP) - I run mine at 1.5psi using a Carbon Doser regulator.

Ah! This is funny I checked the link you gave me and saw the picture and was like hmmmmm i've seen this kind of check valve somewhere in my "thrown around stash", I looked and BAM I found it, I though it was a cheap check valve but I guess it's not! I hooked it up and it works excellent!! If I only knew sooner!

Thanks dude!

I need a replacment CO2 check valve too. I am looking on Ebay at this one Check Valve for CO2 Air Pump Tropical Marine Aquarium | eBay. Just do a search there are all kinds of them on there.
