Thanks for the reply. What I am trying to figure out is why when I
open the T&P valve I get this rusty looking water for a few seconds and
not when a faucet is opened. I am going to replace the anode rod to
see if that helps next.

The rusty water is probably caused by rusting of the spring and other parts
in the outlet of the valve. Depending on how the outlet is pointed, some
amount of water likely stays in the outlet where the spring is located.
Opening of T&P valves is not generally recommended for this reason.
