The valve should be connected to a discharge pipe (also called a drain line) that runs down the length of the water heater tank. This pipe is responsible for routing hot water released from the TPR to a proper discharge location.
How do you drain a pressure relief valve?
For most units, open the water pressure relief valve by simply lifting the valve up until the attached brass stem rises. When you do this, hot water will rush out of the pipe near the bottom of the water tank. Then, push the lever back down to close the valve and stop the water flow.
How much condensate does a tankless hot water heater produce?

Where does water heater pressure relief valve go?
How to Find the Water Heater Pressure Relief Valve. Also known as the temperature/pressure relief valve, or the TPR valve, this valve is located near the top of the water heater. It usually features a lever you can lift up or down and has a discharge pipe that runs from the valve down to the water heater’s base.
Does a water heater have a drain pipe?
When it opens, hot water comes rushing out of the water heater and through the temperature and pressure relief valve drain pipe. This release of water prevents the water heater from exploding due to excess pressure and temperature.
What is code for water heater pressure relief valve?

3) Each TPR valve must have its own discharge piping, not shared with any other devices or equipment. In the example below, an upper pressure relief valve drain (not visible behind vent connector) has been tied into the drain for the lower one.
Can you use PEX for water heater pressure relief valve?
Can you use PEX as discharge pipe at water heater temperature and pressure relief (TPR) valve? Yes. PEX (cross-linked-polyethylene) is rated for water distribution by the International Residenital Code (IRC) at Table P2906.
Can you use PVC for water heater relief valve?
No. PVC pipe is not rated by the building code for use with hot water, so the installation shown above is wrong and unsafe. If the temperature and pressure relief (TPR) valve opens because the water heater is overheating, the water will be over 200º F.
How close can PEX be to a hot water heater?
The Uniform Plumbing Code (UPC 604.13) states that “PEX tubing shall not be installed within the first 18 inches of piping connected to a water heater.” But the UPC is not used in all jurisdictions.
