Shower – Kohler Push Button Diverter Leaking from Shower

shower

My plumber just installed the fixtures in my shower/tub and the shower stays running when the tub spout is running. I can tell he didn't even test it because when I turned on the water, I could hear the air getting flushed out. Even with the tub spout running at a low flow, the shower still leaks. All parts are brand new and I highly doubt the diverter is defective. Any feedback or tips would be appreciated. I called the plumber but he hasn't gotten back to me yet.

Here's a photo before tiling. Any ideas here? I'm fearful that we'll have to cut the drywall on the other side to fix this…

So it looks like it was a bad part, see the o-ring missing below. BTW, you just need a deep socket wrench to remove the diverter, I wasted a few hours looking for plumber's wrenches before figuring this out...lol.

Glad it's working now but this valve kit was brand new, seems odd that something so critical would be missing. Also the part that I pulled seems used or refurbished (see discoloration). I hope the rest of the valve is ok.
