Report "blue clips. I am a complete novice and don't even know the names of parts ie like euschueon or whatever. I am desperate..I am tired of no pressure or not hot enough. How do I adjust the groved thing and with what and which way do you turn it...left or right and how much? I have tried adjusting the left and right screw...when I set them both there is no water flow..just trickle...so I slowly adjust each with the shower on and cannot get the correct balance of pressure and hot enough...my water heater is at max and the water in kitchen and sinks is very very hot...so do I adjust the groved thing in the ceter which just happens to be missing any colored clips..and what do I use? HELP"
