I am trying to replace the drain valve in my brand new A.O. Smith water heater that I installed three months ago. I drained the heater but the plastic drain valve won't budge. The drain valve in the old 12 years) heater came out without any problems.
Do I need to wait until the heater has cooled first? How can I remove it without breaking it?
