Question re replacing faucet washer

I need to replace the washer in the hot water faucet in my basement utility sink. Picture below (Pls ignore the duct tape etc
image.jpeg
I am also in the process of replacing the plastic drain tube).

I obviously need to shut off the main shutoff valve, my question is with regards to the hot water and hot water tank. I am assuming I need to open the hot water faucet to drain all the hot water before replacing the cartridge. If so, this means the hot water tank will be empty for 15-30 minutes. So should I turn off the hot water tank first before I replace the cartridge?

You don’t need to drain the water heater, just the water in the lines.
Yes shut off the cold water inlet shutoff on the heater to prevent possible siphoning
Make sure you replace the faucet seats if they aren’t smooth as that’s likely the underlying issue

You’re looking at an Emco faucet

Once you shut off the main water line, the hot water tank and lines have no pressure. The hot water in the tank won't flow. So no, you don't need to drain the tank.
