New Check vaulve

[lucky45acp]

I was looking for a (one way vaulve) when fermenting. to exaust CO2 from my mash container. I got a hand siphon, used to siphon kerosene , from a kero container. I cut it down just enough to expose plastic one way vaulves, and then inserted it into my mash container and it works Great! I could buy one,but I like to utilize what I have . Thankyou,

You really don't need a check valve, a simple blow off tube is what I and many use. Some here don't use anything and just leave the lid loose. Mr P made a pretty cool little deal with a ping pong ball and I think he used a pvc male adapter. Then there is always the standard bubbler sold at all home brew shops

A hose into a container of water works just fine as well... I have a topic kicking around here somewhere that explains how I've made airlocks in the past out of a pill bottle, a sharpie marker, and a stick pen...
