I am stuck while remodeling my bathroom and want to seek your advice.
1. I want to change shower valve handle and try to avoid soldering. I have already removed the original handle and plate but stuck at the cap. I think I can screw in a replacement handle, e.g. Pfister's universal handle, if I can get rid of the original cap. I cannot unscrew it with a plumber's wrench. Any suggestions?
2. I am trying to replace the shower head as well. After stripping the old head, I am stuck with the spherical end that does not come off at all. Any thoughts on it?
Thank you all for your attention.
