903.33 Cartridge pressure very low
These cartridges are sometimes stiff to move. You maybe able to get it to move after you have sprayed the area with WD 40.

How can I get another key?
Also does it matter if the cartridge is open or closed when trying to turn it to the low pressure setting?
Thanks

The red key will turn it but it can be very difficult, if you find it impossible to turn then return the cartridge to us we will send you a new cartridge and we can set it to low pressure for you if you put a note in with the return.
Also just to check you don't have a pressure problem it may be worth giving the valve a flush out when the cartridge is removed
This will take two!
If your valve is recessed pack an old poly bag round the valve to divert the water into your Bath / shower tray then turn the hot and cold valves on one at a time and allow the water to flush through for about 15>20 seconds.
The person who is helping you should watch that the water is not going anywhere that is going to do any damage. Also they should watch that the amount of water coming from the hot and cold they should be roughly the same.
