What happens here

With the water level lowered, the old T&P valve can now be removed. Use an adjustable crescent wrench, like the DeWalt brand shown, or a pliers wrench (such as a Knipex model) to unthread the old valve from the water heater. The video implies that the valve may not be extremely tight, sometimes even 'hand tight' initially, but a wrench provides the necessary leverage to break the seal and unscrew it. Once removed, inspect the inside of the old valve; the video shows significant buildup, which can contribute to malfunction or reduced performance.

Goal: Detaching the faulty T&P relief valve from the water heater tank.

What they say

Hide

on. So, I grabbed two different size shanks here. It's better to take something back at the end of a job than to have to run out and get something else. So, we cracked this. There we go. We might want a crescent wrench or a pliers wrench like this, but this is hand tight. You can see right there that threads are starting. This is going to be this inch and a quarter shank. I like to go Teflon and then pipe dope. You only have to drain your tank to the bottom of the T&P
