Shower not getting hot enough anymore

Postby tommyhmt » Tue Oct 31, 2023 1:38 pm

Our shower has stopped getting hot enough recently, it's definitely not a heater issue because rest of the taps and radiators are fine. I first thought it was maybe the anti scalding device needed adjusting but can't tell from the picture if there is one or not as the ones I see online are all plastic. If it's the mixer or shower unit that needs replacing then that's beyond me I'm afraid.

Simply Build It

Hi tommyhmt,
You probably have a thermostatic shower valve and the problem with these is that minerals in the water build up on the thermostatic mechanism and stop it working.
You could try operating the temperature control a number of times over its full range. If this doesn’t work you could see if a plumber can replace the innards, if not a new valve my be your only option.

I asked Bristan for the model number but they said
"The shower is the Prism inline shower which is discontinued. Unfortunately we have no direct replacement for these showers"
Does that mean I now need a entirely different shower or is there another way I can order the part required for the plumber to fix?

Hi tommyhmt,
If you search online for bristan prism cartridge there are a number of options, whether any of them are the right cartridge and are in stock? - you will have to make enquiries of the suppliers.
