shower drain flange

[Richard S]

I just installed the shower drain in the shower I'm rebuilding. It'll be a tiled floor (pre-slope, pan liner, mortar & tile). The lower flange of the shower drain lifts off the plywood ever so slightly (maybe a 1/32" of an inch) instead of sitting perfectly flat. As I can't screw the lower flange in place without messing it up, I was wondering if I could apply some glue to the bottom of the flange & weight it down till the glue sets. Is this a good idea? Am I worrying over nothing? If I do this, will the PVC cement bond to wood, or should I use some other adhesive that's safe for PVC.

I'd really appreciate some insight from those who travelled this path before me.

Thanks so much,
Richard
