This question is regarding Sirrus/Gummers 1850/968 Series Valve Seal Service Kit with Silicone

Temperature control

Mixer will not deliver fully cold even when temp control is turned fully clockwise. Will the seal kit cure this, or do i need a new wax cylinder? Can I buy a wax cylinder on its own or do I need to buy the whole brass cartridge for £150??

You should test the thermostat first and replace it with the above if it is faulty.
