Hi,
I am trying to find out what size spanner I need to undo a shower recess tap and replace the washer/valve. I have successfully changed this on one of two taps. I managed to undo the first one with no trouble and change the washer. However, none of my fixed size spanners are big enough. I only have a shifter that extends to the right size. The other tap is on really tight and in an awkward position and I can't get the shifter tight enough. It keeps slipping and I don't want to burr the connection. If anyone can advise on what size spanner I need to undo the tap. Is there a standard size? Any help greatly appreciated.
Peter
