Strange LP Gas Surge

[accusedslacker]

Hopefully I have this in the correct section. I apologize if I missed it. I'm in the process of building a Brutus 10 kinda-clone. I have a propane bottle hooked up to the gas beam via a low pressure regulator. I turned on the bottle and charged the beam then I lit 1 burner. I get this gas surge about every other second the whole time. The regulator blows off then stops and the flame gets a little bigger then repeats. I can't smell any gas from the regulator but I can feel air flow coming out with my hand. If I plug the relief valve with my finger it slows down the surge but it still happens. Do you think I have a bad regulator or do I need a POL fitting instead of a QCC nut or am I off base all together? Thanks for your help in advance, Mike

Beautiful stand. Do you have some shots of the regulator. It sounds like that may be the issue. I have seen some regulators that are low pressure, but considered secondary regs and are not intended to reduce the hundreds of psi out of the tank as a primary would. Im not saying that is the case but could be a possibility.

Also which burners are those?

Here's a picture of the regulator. The burners are just no name 6 inch burners. My buddy has the same with no problems.

I would replace the regulator. It sounds like it could be sticking, which is resulting in a larger hysteresis than intended, hence the surge. Sometimes this can be resolved by tapping it with a large heavy object, but rebuilding/replacing is generally the better approach.

Agreed, for the relatively smaller price of a reg you may completely solve the issue. If its a newer one I'd contact the folks where you bought it from and see if they'll make it right.

Could it be the tank was overfilled and the regulator is dealing with slugs of liquid?

Problem solved. I hooked up a new regulator and all is well.
