Can a Triton Topaz T80si 10.5 kw Heater Can Assembly (Part Number 83307100) be fixed ?
The shower is running freezing cold when temperature on high. The part has been discontinued and due to the unusual shape of the shower unit and where the pipe work is positioned compared to most showers, it would be a big job to replace the complete shower unit.

two thoughts
1. check rules on diy repairs (UK) water & electric
2. have you tried www. spares4u.or other sites they might have pattern parts.
reason discontinued might be a part not held for long as not called for
Old shower unit.
No manufacturer is obligated to stock / supply spare parts. Only buy "pattern part"( same part made by another manufacturer) from reputable outlets, to many dubious item on market not fit for purpose.
