Help on using IP Gauge to test reg

[Brilig]

You have a great start, but I suggest that you can make this whole ball-o-wax simpler by separating the concepts of inspection and servicing. You should inspect regularly and then service as required. As a vacation diver I inspect every dive trip (1 to 3 times a year). Service happens every 200 to 300 dives... I am currently in the process of replacing my 30 year old hoses...

If you feel you can perform inspection, you may want to think about performing your own service? As you have been made aware, there are lots of reg failures caused by bad (unneeded?) service.

And yes - my perfectly functioning regs have been screwed up by a LDS service tech...more than once - shame on me!

P.S. My answers based upon a Sherwood Piston first stage are:
2: Creep can be instantaneous
3: Purging and breathing are the same
4: 10 PSI on my regs
6: instantaneous
7: WTF?

You don't know how good it is to hear that I'm not the only one with 30 year old hoses.
