Step 3 · Remove the Discharge Pipe

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

The T&P valve has a discharge pipe, typically made of copper or CPVC, that directs water towards the floor. Using a pipe wrench or a large adjustable wrench, grip the fitting that connects this pipe to the T&P valve's outlet and turn it counter-clockwise to loosen and remove it. Be prepared for a small amount of trapped water to spill out; having a small bucket and rag handy is useful.
