So over the years I've acquired quite a few different regulators and various parts whenever a deal presented itself. Finally got around to trying to assemble a few things so I can pressure test, and then decide what setups to sell and what to keep etc.
One problem is a Matheson 3102. Looked like a nice reg, but after purchasing it I found the output pressure is limited to 30 psi. Still should work for aquarium needs, so got new gauges and started assembling. As I'm going through the pressure testing I found the first stage is fine. However, when trying to get the working pressure up, its maxing out at around 13 psi. I'm honestly not even sure what this might mean?
The other problem is with a Scott regulator (the model number escapes me at the moment). This one has a pressure relief valve between the first and second stage. Once I got it set up and hooked it to a CO2 tank, the pressure relief valve blows immediately upon opening the tank valve. I dont even think the high pressure gauge moved before the valve opened. So I thought maybe it was a faulty valve (the stock one is a multi piece unit with a spring so I though maybe I was missing something). I had another relief valve to fit the threads (but dont know the exact specs of that valve....i think it was only for 30 or 45 psi maybe). It too opened as soon as I opened the tank valve. So does this mean the first stage of this regulator is shot? Could it be that I need a pressure relief valve with higher psi? Or could I have screwed up which ports the gauges and valve gets inserted into this particular regulator?
