Thermostat shower sensitive temperature control

[pr1970ster]

hi all

We have a thermostat shower in our shower room the type that has the mixer exposed in a long chrome barrel , power on the left and temperature control on the right. It is very sensitive to movement of the temperature control, it goes hot to freezing with mm of movement. I'm assuming the cartridge is at fault but not knowing which brand of shower it is , is there anyway of getting a replacement cartridge?

Thanks

Paul

Sure, its very similar to this.. havent removed the cartridge as i didnt want to do anything until I know i can get a replacement

when was it fitted?

i ask this as if hot and cold are mixed up i.e been piped up on wrong sides of bar mixer shower,then that is exactly what will happen!! No control of temperature

Was installed about a year and a half ago. ta

otherwise if no work has been done in house of loft and pipes arnt swapped wrongly then it will be the cartridge.
ok

just double check ...turn on and touch left side fitting on bar mixer and make sure it gets hot, if it does get hot then its been piped up correctly

I`ve touched the inlet pipes when its been running and they are around the correct way. Main question is if it is the cartridge, can I just take it out and take it down the plumbers merchant or is it more complicated than that, ie finding the make and model of the shower thermostat first?

There easy enougth to get out, have a really close look on the ends and round the back of the shower ad most the time something is faintly written on or a picture which will narrow it down to a brand of shower

No , nothing written on it. Think its probably just some cheap chinese import. I noticed there is a kind of grub screw underneath the thermostat side. So i`m guessing its just undo that and a philips screw on the end behind the cover to remove the cartridge.

unless its still under warranty id seriously look at cost of part v's new bar mixer as you may find getting new mixer is better for you

actually think i found the whole thermostat shower valve on ebay for £27. it has the same decals on it but slightly updated appearance and the attachment is on the bottom not the top. Maybe i`ll ask them if they sell the cartridge separate. or like you say just get a whole new mixer.
