Customer Question

The shower problem is that it is running cold
I have a manual shower with mixer for hot and cold. The flow valve knob and thermostat is all one knob. I know how to turn the water off at the mains and to remove the shower control knob and the enclosure.
My question is, how do i adjust the thermostat to get the shower to run hot?
Sorry I don't know the make of the shower

Hi , if your shower is thermostatic ,ie it controls the temperature wherever you set it , even if other taps are used then the shower cartidge would need replacing. Is it definitely thermostatic?

Yes definitely thermostatic. The control knob has Hot, Cold and Thermostat written on it.

Ok , thanks. It is most likely the cartridge is faulty. After a while they stop operating properly and need replacing.Showerdoctor have a service where they will try to identify a shower model if you send them a photo,however if you can upload one here , I will see if I can identify it
