There are no Logo to be found on the taps. Not after cartridges on there own at this point. Have just replaced the washers on the valves ready for replacing once repair figured out.
Decided to drill out inside of head then got spline internal fitting for a differnt tap and with epoxy putty fitted it in the head. The repair has worked well and been working for 2 months now. When and If it failsI will replace the taps completely.
