You have to shut the fuel supply gas / oil or electric or indirect and isolate the tank from the system using isolation valves and use the blow /drain down valve to lower the water level below the T&P and then unscrew it and replace it with a T&P with an AGA / ASME rating GREATER then the input in BTU's but in no case less then 3/4"

Why is my hot water heater whistling and how can I fix it?
Your hot water heater may be whistling due to a build-up of sediment in the tank or a faulty pressure relief valve. To fix it, you can try flushing the tank to remove sediment or replacing the pressure relief valve if it is damaged.
How can I turn off my hot water tank?
To turn off your hot water tank, locate the shut-off valve on the cold water supply line leading to the tank. Turn the valve clockwise to shut off the water flow to the tank.
Can you shut off the inflow valve to hot water heater for a day without harming system if so should pressure valve be left open and limited usage of hot water?
If you have a leak on the hot water somewhere in the house and the water input into the tank is not running, the tank will lose it's water. And if it is an electric tank, the elements will burn out. Gas hot water tank should be no problem. Pressure valve does not have to be open.
What is the purpose of the hot water tank relief valve and how does it function to ensure the safety of the hot water tank?
The purpose of the hot water tank relief valve is to release excess pressure and prevent the tank from exploding. It functions by opening when the pressure inside the tank exceeds a safe level, allowing hot water to escape and reducing the pressure to a safe level. This helps ensure the safety of the hot water tank and prevents potential accidents.
Why does hot water tank spurt water out over flow valve?

How can I turn off a hot water tank?
To turn off a hot water tank, locate the shut-off valve on the cold water supply line leading to the tank. Turn the valve clockwise to shut off the water flow to the tank. This will stop the heating process and allow the tank to cool down.
What is the purpose of the hot water tank shut off valve and how do you operate it effectively?

Is my hot water tank pressure relief valve leaking?

What causes a pop off valve leak on hot water tank?
If you have an expansion tank in the water line near the hot water tank there may be a small plastic cover over a valve that looks like it is an air valve from a tire/tube. If you depress it and water comes out it means the tank inner membrane is compromised. Replace the tank. Home Depot has them. They're about 3 or 4 gal and adequate for a typical home situation. The pressure relief valve leaks because when you use the hot water it comes out of the hot water tank and is replaced with cold make-up water from your water supply. As it heats up it expands. Since the expansion tank is full due to the leaking membrane in the expansion tank, the expanded water goes out the expansion valve til the pressure is equalized. I put a small catch pan under it til I could replace the exp. tank. Be careful when you remove it(mine was simply screwed into a fitting in the water line) the tank as it will be heavy and awkward. Goog luck.
What is the proper procedure for safely shutting off the gas valve for a hot water tank?
