First time I took out cartridge I found little pieces of sediment that I cleared. Put it back no change, I blew it out for 30-45 seconds and got hot and cold water. Then put cartridge back in and same result. Its hot and cold correctly so it’s not a case of switched pipes, just no pressure. As I open the valve I have about half pressure at 2:00 with cold and when I open to 12 loose almost all water, open to 10 and trickle of hot.
It seems that the cam nut is too tight?? I only hand tightened, but when I loosen it I get more water flow but then I can’t seem to turn off or get any real mixing of water temp. It’s like the springs are stuck. I’ve taken apart the cartridge and made sure there was nothing inside of it. I lubricated all gaskets and moving parts to no avail. I have read all through installation manual and checked online. There is a spacer included with this kit but that is for the trim and not for the cartridge.
There seems to only be one way that the spring and gaskets properly fit, narrow end into the black gasket, larger end of spring into the hole. But maybe I’m wrong and the springs are messed up.
This is out of the box delta classic tub/shower single handle set up. Sooo frustrated.
