I was reading in to Technical courses and requirements, and came across with some differences, some advocate for full independent doubles others with an isolation manifold.
I only can see that if you have an isolation valve connecting doubles that you have 160cf air source constantly but the down part is that in the unlucky event that one of your regulators decide to take a dump on you, then you lose some air from both in the time you close the isolation valve.
With fully independent doubles you just close the failing regulator tank and have no effect of the volume of the other.
I only see 3 more places that can leak on a isolation valve system, and 3 more places that I have to do maintenance
is there any purpose for this isolation valve, what is the benefit of them ?
different scenarios, different doubles arrangements ?
what arrangement you dive ?
if I'm missing something, please share your light, much appreciated, as well as your opinion and preferences between both systems.
