Step 3 · Disconnect Discharge Pipe

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

The T&P valve has a discharge pipe that directs released water safely toward the floor. This pipe must be removed before you can access the valve itself. Using a large pipe wrench or adjustable wrench, grip the fitting where the copper discharge pipe connects to the T&P valve's outlet. Turn the fitting counter-clockwise to unscrew it. Have a rag or small bucket ready to catch any residual water trapped in the pipe.
