I have made a spunding valve recently after reading some threads here. I primarily plan on using it to naturally carbonate beer and therefore need an absolutely leak free system. Based on recommendations here, I used an Airtrol pressure release valve (60 psi max). Unfortunately, after hooking up the spunding valve directly to gas and setting a pressure, the valve slowly leaked. Specifically, it leaked directly through the airtrol relief valve output (losing about 10 psi through the night). The rest of the connections where sealed with yellow gas teflon tape and were checked submersed under water and were leak free. Somehow the Airtrol relief valve is leaking pressure (it slowly releases bubbles through the output port). Has anyone else had this problem?
Right now a new Airtrol relief valve is on the way (McMaster's customer service is amazing) and hopefully this one will not have the same slow leak.
