I assisted in troubleshooting a friend’s keg system set up with double regulators. The kegs were not holding pressure, or replenishing it as it got absorbed or had a pint pulled off. Doing this in words across country is challenging to me, I like to be able to have it in my hands and work from there!

He would set his pressures and then come back the next day to have them reading down at 2-3psi. He was running three lines off of two regulators, the furthest from the cylinder having the wye split. Each of the outs had shut offs on them. The cylinder was still showing full and we were able to verify that by pushing in the QD and turning up the pressure on the first reg. HIISSSSS.

It finally came down to trying to leave both regulators at 10psi. The regulators can only restrict what comes through it, the reg closest to the cylinder needs to be higher than the next, otherwise it doesn’t work properly.

By switching around his lines to where he wanted stuff, it seemed to work over night. Then later both regs read upwards of 30psi! There is more going on there we still have to narrow down. Stuck gauges? Who knows. What a fun hobby!

Cheers!
