Spotted a leak coming out from under our ensuit bath last evening. Traced it to one of the taps being cracked open and a leak from the diverter valve that had found a hole in the silicone seal. Have got the bath out but before I take the diverter to bits I wonder if any body knows what I will find in there. The diverter button assembly looks to have a couple of flats on it so I assume it unscrews but I thought I would gather the collective wisdom before I tried.
