The regulator in the front was reading 105 psi and it should be around 80. That in turn caused the valve to fail and hopefully has not damaged anything else.
Thanks for everyone's input.
Replace the relief valve just because. And personally, I would turn the pressure down to about 60 MAX. You'll probably need to adjust your shower head to ge tthe spray back, but it's better for all involved.
