As the title says I can't loosen this bit on the wall. There was still some play at the wall. I know I did have the plumbers tape a bit thicker at the back when I wrapped it around and assumed that's why it wasn't getting tighter, so I brought the shifter out sound the nut for the hose holder. That got it a quarter turn only and now I can't even turn it back. What do I do? I now know I shouldn't have used a shifter.
