Some plumbers prefer using the tub port, as it's not as restricted.
I have 2 seperate shower units in my stall. Plumber piped one valve correctly, but piped one with shower pipe exiting out of the tub port on valve. I seem to have a bit of water hammer or spool play in cartridge now.
Is it OK to pipe to shower from tub port (lower) on valve or should it be redone to go out of shower port (top) on valve?
Thanks in advance.

I ALWAYS do it that way as long as the valve is 180 degrees symmetrical so it can be inverted. Doing it that way can avoid some nasty problems in the future.

And, what problems in the future are speaking about? I may have them at the present.
