A bit of a question for those with cylinders of CO2: if you turn off your gas at the cylinder, do your primary and secondary pressure gauges drop at all over time?
So after clearing up from the mess of the roof (long story) I've finished plumbing in the brew space for CO2 supplies in several locations, each of the three outputs from the combined primary and secondary regulator go into manifolds, with each of their outputs on ball valves. If I turn off the gas at the cylinder when all the manifold outputs are closed the system should then be entirely closed, but I've found that over the course of about 2 days the pressure drops to zero on all the dials and primary. This suggests that somewhere there's a leak. I cannot though for the life of me find it. I've used leak detect spray all over the pipes, cylinder and everything in-between. I've now taken to trying to isolate the outputs one by one using a JG blanking plug, and still can't find the leak.
It's clearly a very slow leak - is there any other clever approach or can anyone suggest a different leak detect spray - I'm using this one at the moment Ambersil Leak & Flaw Detector Spray, Detector
