My shower hose is leaking at the join on the wall, I have unscrewed it and put a new washer in but now the part where the hose screws to the wall is cross threaded and is leaking even more, it's only plastic so I'm not surprised. Can I unscrew the part that is on the wall and replace it?
I've tried to move it but it seems pretty solid, will I damage the wall if I keep trying?
