Temperature and pressure relief valves
The T&P valve should be checked twice a year to make sure it works. It is located in front of the water heater and has a small steel lever with open holes. Sometimes a pipe is attached to it. Raise the lever to ensure water. If it fails, open it several times. If it still fails, it needs to be replaced. If it leaves a little water, but leaks, tap it lightly with a lever when it is down with a hammer. If it is still leaking, replace it. The pipe that can be attached to it can run in the sink, outside the house or on the floor. Its diameter is about 3/4 inch. The pipe should not be closer than 6 inches from the ground. You can have a threaded union between the T&P and the pipe, also making dis-smoothing easier with the cast steel gate valves manufacturers.
Gate Valve for Your Hot and Cold Lines
Consider installing a gate valve on your hot and cold lines. They make it possible to open or close the line. If you have a leak or flood emergency, it is much easier to turn off the water heater than the main pipe. Make sure you do not mix steel and brass in the joints here or the steel will corrode. If water ever escapes from the nut that pushes the handle on the gate valve, turn off the water and remove the nut from the threaded stem and wrap it with Teflon tape or use graphite packing material. This will pack the nut into the gate valve and prevent leakage. If you decide to put a gate valve, make it a ball valve instead of a turning mechanism type valve. You can see if the line is open or closed.

Wrap the Teflon on the water heater on the nipple. Now attach the ball valve. If you have a plastic drain valve that looks like a hose bib, remove it by replacing the valve completely. A little water may leak when installing a new valve, but not too much. Wear gloves to prevent drainage.

Tighten the connection forward.
Inspect your gas water heater vent
