Hello
I am trying to remove the toilet shutoff valve from the wall to replace it. I was told at the home depot that it would be an easy fix. However the valve keeps turning and won't come off, I can even turn it with my hand. What can You suggest?

You need two wrench to remove the angle valve see the image below, Thanks.

Are vyou attempting to replace the angle stop? If so you can use the old ferrule and compression nut. Good luck, Tom
