No hot water on high pressure.

Hi,



I just installed a new 451.71 Mira Excel cartridge.



Everything works fine as long as the flow is only half way. The temperature is on 8 and the water is boiling hot but when I turn the flow up to full pressure the water temperature drops to luke warm at best.



I've tried to adjust the temperature control but that doesn't work either.



Any suggestions?

Regarding the temperature fluctuation or cool running it could be afaulty cartridge however to check this, if you have a combi boiler, see if you can get hold of the hot supply pipe before it enters the shower orperhaps as it leaves the boiler.

Ifwhen holding this pipe the temperature fluctuates or goes cool then the problemis not with the shower but more likely with the boiler as the shower can onlydeliver what the boiler sends to it.

Disregard the temperature at the taps as they have a different flowrate.
