I think I may have just learned an expensive lesson. I bought a Matheson 3122 over a month ago and I just got everything together to leak test it. I jumped on it when the regulator thread was running and I took too long to get the CGA 320 nipple, tank and enough time to setup the test.
I'm a little unsure of the step 1 test. The regulator has a shutoff valve on the output. Should that be closed for step 1 testing? I closed it.
The LPG has at about 40 psi with the regulator handle turned all the way counter clockwise. About 20 minutes later I looked and the LPG is pegged. That means I have a nice paperweight, doesn't it?
Should the regulator handle be turned tight counter-clockwise, like the tank shutoff or just loosely at the end of counter-clockwise travel?
