This question is regarding Triton HP Mixer Valve Cartridge (including seals) - 83304970

LP/HP confusion

I have a Triton combi mixer shower in a loft conversion fitted with a shower pump in an otherwise gravity fed system (NOT a combi boiler). The plumber originally fitted an LP cartridge, but when this failed after about 10 years the supplier recommended I fit an HP cartridge. 10 years on this has now failed and I'm unsure as to whether I need an LP or HP cartridge, given that both seemed to work. The shower pump (Stuart Turner Monsoon) delivers 2 bar max.

Yes the valves have been rebranded they are now LP and Combi

However if you have a combi (HP) and it is working OK then go for the same thing again, it is likley that the previous plumber fitted a conversion kit to change the housing to accommodate the Combi cartridge so stick with that
