What happens here

After the new T&P valve is installed, the water heater tank needs to be refilled. Locate the main cold water supply valve to your water heater (usually a green handle valve as shown in the video) and slowly open it. As the tank refills, open a hot water faucet in a nearby sink or tub in your home. This allows air trapped in the water heater and hot water lines to escape. Let the water run from the faucet until it flows smoothly and consistently without sputtering, which indicates that all the air has been purged from the system and the tank is full. Once the water flows smoothly, close the hot water faucet.

Goal: Completely refill the water heater tank and eliminate air from the hot water lines.

What they say

Hide

drain your tank to the bottom of the T&P valve. And you can see the build-up in this. I'm going to just go right back in. All right, we can get enough torque with this bad boy. So, to get a little more straight. All right, we go. I'm going to slowly open that to fill this up. Just getting all the air out of the line. We got to turn the gas on. Switch this over to pilot. Click that down. Hit the igniter. You want to hold this down until the pilot light stays on. We're able to flip this to on and it fires up.
