now I'm not sure if I have a safety pressure-relief valve. what's that look
like?
I think I'll just plumb in a length of pipe to replace the pcv. if the fixtures
explode, we'll know why.

I can't say that you don't need this, because I'm not an expert and
perhaps there's some sort of special situation I don't know
about. But I can say that I don't have any such thing on mine. I
haven't seen one on other systems I have looked at. I recently
replaced my tank, and there was no mention of this in the
instructions for recommended ways to configure the system. Usual
control switches maintain 30 to 50 pounds, or 40 to 60 like
mine. Perhaps if yours was going to 70 someone added this in a
misguided attempt to limit the pressure, rather than adjusting or
replacing the switch like they should have done. Just a guess
though. What you should have, though, is a safety pressure relief
valve, and I would think that would have to be located before your
pressure regulator to properly protect the system.
