So, my hot water knob in my shower leaks when it's completely shut off. I know how to fix it, but my question is with the hot water heater. There is no shut off b/n the hot water heater & the knob, so I need to shut off the cold line into the hot water heater. Some of my research has shown I need to cut the pilot/gas to the heater as well. However, I cannot seem to find a spot to relight the pilot when I'm done with the fix.
My question is, do I NEED to shut the gas off, or is cutting the cold water line alone OK?? Will pressure build up to the point of explosion?? I would rather not mess with the gas if I do not have to. Can anyone verify that if I cut the cold water line into my hot water heater, I will be able to change the seal on the hot water knob in my shower without causing any issues to the hot water tank??
Thanks for your help!
