If I shut off the cold supply to the water heater will that shut off the hot water so I can change the sink faucet?

If I shut off the cold supply to the water heater will that shut off the hot water so I can change the sink faucet? No! You will still have pressure on the cold side. Shut the water off at the house shut of. Good luck, Tom

Understood the cold water has to be turned off. I was asking about the hot water :)
