We have just used our new to us 1996 swift conqueror. I was trying everything out for the first time and found a water leak in the showeroom which showed itself coming from the panel below the mixer taps. I found that the pipe to the shower/basin had come adrift. In order to make a repair I took the 4 screws out the mixer unit and tried to lift it out but it wouldn't come. I think the best way will probably to remove the shelf unit below the taps and have a go. Does anybody know how to get this unit out without damaging it please? Thank you, Paul.
