Erm... Not sure it's thermostatic actually!
We have a combi which powers another shower and that holds the temp ok .
If it was just a mixer shower, is there any reason why the temp would fluctuate? (Other than the boiler of course)
Any ideas how to remove the thermostatic cartridge in my shower? It's running hot and cold so checking if it's clogged or something obvious.
Thanks in advance.
