I finally got the temp down to about 135*F and the TPR valve remains
closed.

It remains a mystery as to why the thermostats were reading low and
yielding too high a temperature.

The water pressure is about 60 PSI.

Why would a TPR valve fail in a low temp mode?

I plan on replacing the TPR and using a tubing to join the 3/4" copper
tubing.

There should be a TPR open sensor thingy that cuts off the power. You
waste energy and water when it fails. We just returned from a 10 day
trip and luckily we had the water heater power off.
