I have a Blanco 440045 Alta soap dispenser that is broken. I want to remove it from my sink.
Unfortunately the piece highlighted in the image is stuck due to years of moisture and cannot easily be unscrewed. It seems impossible to remove the dispenser unless this piece is unscrewed or I cut through the main body piece of the dispenser.
What is the name of this piece?
Is there a tool I can use to unscrew this? Unfortunately it is completely round so I don't think a basin or socket wrench will work.
Would a hack saw or oscillating tool be able to cut through the threaded main body piece (which should allow me to remove the dispenser)?
Thanks for your suggestions.
