I just installed a new Pegasus shower, 9000 series. I replaced all the plumbing going to the device and added a Tee before the shower valve for the hot and cold to feed another set of faucets, I get great pressure from the two lines that tee off. My problem is I get really poor pressure from the hot side of the valve and great pressure from the cold side. I adjusted the limiters, that doesn't help. Any suggestions would be great!!
