Removing taps from tower

[SB]

Hi,

Can anyone give me any advice on how I remove the taps in the picture without butchering them? All I seem to be doing is taking chunks out of them. Is there a specific tool designed to remove taps from towers?

Thanks

Try slacken off the brass nut. Then unscrew the whole tap from the tower..
