Regulator, humm, I was thinking on running a cycle with the shure cycle or the Triton to measure "real" capacity, this done with the regulator so I can check both at the same time, on the Triton I will try it also without the regulator but it does not make much sense.

On the other hand, being redundant, who do we know when one pair fails?, unless we run thru a cycle like I just described, I really don't know what else to do.

With all the mone invested in this models and top of the line equipment it is not comfortable to be scared of a failure.
