Aqualisa 099301 diverter
 

I have had the Aqualisa shower diverter for several years and recently it has started to leak quite badly. I called Aqualisa and asked initially for spare washers as I thought that might be the problem. They told me they had no spares so I asked for a replacement and was told that the model I had was obsolete, having been replaced by and updated version. This version will not fit in the space I have without major redesign of the shower area. Does anyone know where I can find a replacement for the earlier version? I've tried MyTub, shower doctor, NSS etc with no result.
