Strange problem - New Shower Panel

[Tony Mazz]

Hi I bought a new shower panel for my new reno shower connection and strange but true only the cold water would shoot out.

So I swap the connections, and you guessed it only the hot water would shoot out. Ok so I when back to Lowes and got another unit the same model.

Would you believe I had the same problem. What the heck is going on?
Anyone have a clue?

I took the shower panel off and both hot and cold water are shooting out of the pipes. So I have no clue what to do here.

I phone the manufacturer up and they are going to send me a new valve replacement hoping this would clear up the issue.
Anyone have any suggestions thanks Tony Mazz

Without a brand and model...it's kind of hard to guess.
