See old biscuits pic - it's at the top by the looks of it. The hot out to your faucets connects to the back of that mixing valve. It only squeals if turning a faucet on.
The cold line into the heater is on the bottom. That line running to the top valve is cold being added to the hot water in the mixing valve.
