Should this turn all the way flush?
Hi,
Ive recently installed a shower and wanted to double check something. I have an overhead shower and have noticed that when the water is set to hot, there is a slight pressure job from the overhead shower head, whereas when you turn the temperature cold again, the pressure goes back to full blast again.
Is this normal, and is this range of motion okay and got anything to do with the hot water pressure being a bit lower? I've attached photos of how the temperature valve looks at each extreme of the range of motion - I've been told at each extreme it should turn to be flush with the rest of the setup?
TIA!
