No-caulk shower drain - can the rubber gasket be cut to reduce height?

[Rogeryen]

As stated, just finished installing the acrylic shower base on mortar base, and the drain end is just slightly higher than intended (still fairly level though) but the rubber slip gasket now seats maybe 1/8” higher than the ABS pipe, exposing the inner cavity of the gasket.

Will that be a problem as there will be a small amount of water pooling in that cavity (in between the two inner “rings”)? Or is it safe to cut the rubber gasket from the bottom to reduce its height?

The rubber should compress when you tighten the ring. Even if it stays proud of the pipe, it would not create any problem

KUDOS for using a brass shower drain!!!!!
If over a crawl space, then fine with that one bead on the gasket. If over finished space, that would be a higher standard I'd prefer to see that final inner bead of rubber doing its job. no time to look up if I use "its" or it's correctly.

I wouldnt cut it but dont forget to plug and test your work by filling pan with water

Thanks everyone for your comment. It irks me knowing that there’s water that’s pooling but now I feel better
