Bit of a novice here. I am trying to remove a cold water hooded tap from my bathroom sink. I have been able to remove the pipe leading to the base of the tap and I have had some success loosening and unscrewing the back nut. it is unscrewed up to the point of \\\"what looks like a another bolt\\\" but it seems fastened/soldered to the taps \\\"legs\\\" so there doesn\\\'t seem to be a way of removing the back nut entirely. Will I need to hacksaw the tap? There is also a lot of dirt (actually it looks like hair) on the taps legs making it even more difficult to unscrew the back nut fully. Not sure if what I said makes sense but any help would be appreciated?
