I turned off the heater and the hot water stopped flowing at all faucets. I guess then it's not a crossover. This is a picture of my shower valve.

I ran the master faucet and I could barely hear anything at the water heater. I ran the guest faucet and I could definitely hear something at the heater. I am not sure if this means anything. Master is 1.5gpm and guest is 2gpm.
