I changed the thermostatic cartridge in my shower and I am struggling to calibrate it so that the temperature is comfortable, and the temperature control is logical.
It looks like this, which is a Bristan 00622415
I watched youtube videos, and it seems as simple as turning it clockwise as much as possible until the water is cold, and then turning it back 1 quarter anti-clockwise turns until the water is at a comfortable temperature.
When I try this the water jumps from cold to boiling hot event at a 1 quarter turn, and doesn't seem to gradually get hot as I would expect.
Any advice?
