Hello,
I am trying to remove my current tap so I can install a new one but am having trouble doing so. I am unable to remove what I believe is the locking nut (black tube). Is there any way to remove this or I am doing it incorrectly? I have tried removing by hand and spraying wd-40 as there appears to be minor rusting, but it won’t budge. I cannot find any instructions on removal of this tap.
