Why did you remove the anode of the old heater? Just curious?

Better than curious.
I wanted to learn if the anode was corroded in which case it was a
diagnostic tool as to what caused the failure of the prior tank.

By the way, I found some requirements for the installation of the pressure
relief valve plumbing ... which must "not terminate more than 6 inches (152
mm) above the floor". Darn. Now we need to horizontalize it, creating the
chance of clog causing further danger to occupants!
