hi john welcome to the forums. what sort of shower head do you have? is it one of those rain shower ones?

Hi
It is a 3 position one rain etc

 

[PlumbBobBob]

did it work properly before you changed the cartridge? or was this the reason for changing it?

is there a filter fitted somewhere on pipework to shower??

 

[PlumbBobBob]

is the hose kinked at all even a little bit?

Where is the cold supplied from tank or mains...unequal pressures...cartridge may be wrong type..or not set up correctly...regards Turnpin:43:
