Installing an acryllic alcove tub (Maax) to replace an old fiberglass tub/shower enclosure of same size. Using gerber drain/overflow kit. Just dryfitting everything and found that overflow pipe/tailpiece slopes back away from the tub, to the point that it is torqued up against the bottom plate of the alcove wall seen in the pic. Stepping in the tub you can hear the tailpiece rubbing against the bottom plate. I'm surprised and a bit confused that it's kicking that far away from the tub.
I'm not really concerned that it isn't plumb (should I be?), my concern is that it's already ~1" behind where old p-trap was. If I were to cut the bottom plate to provide relief I bet it would move back atleast another 3/4" if not more. Problem is the Existing trap is only ~1/2" from supply lines preventing me from getting it far enough back to line up with tailpiece, and if possible I'm hoping to avoid having to totally reengineer the trap as Id need to raise it up almost 2" to get it above supply lines, and (aside from that being a PITA itself) I think the resulting slope might be an issue if I do so.
I could push the overflow/tailpiece closer to plumb (towards the tub) and could redo the trap using same design w/o hitting the supply lines, but 1) when I push it to plumb I can actually see the tub flex noticeably at the overflow plate (though not enough to be noticeable in a pic) thinking I might be setting myself up for a crack, and 2) I'd worry that the torque the tailpiece would place on the trap assembly wouldn't be healthy. I thought of using some strapping around the tailpiece and fasten that to nearby joist to relieve the torque...but this doesn't seem like a an above board solution either.
Appreciate any insight.
