Hi Guys,
I'm trying to install a grohe retro fit 27867000 (link below) in my newly renovated bathroom. Before the tiling was done the plumber left a standard 1/2 inch NPT-FIP protruding around 6'2 high out of the wall, and installed a moen valve about 30 inches below this.

The plumber is now saying he can't fit the grohe retro fit shower head due to the moen valve, but I don't understand why this could be, since the retro fit system is designed to work with a standard 1/2 inch NPT-FIP, and is completely separate from the valve. I understand the valve trim will have to work with the moen valve.
I've attached a picture of the valve and the outlet - can anyone help me understand why this wouldn't work, or help me explain to the plumber why it SHOULD work?
Best regards,
Charlie
