Shower tailpiece too short - no caulk shower drain

[Bviper]

Installing an acrylic shower pan with a Kohler K9132 "no caulk" drain. Unfortunately, it looks like my measurement was off and the gasket, which should be flush, rises above the waste pipe by about 3/8ths inch. Wondering if this is an absolute must redo, or will it likely be fine? The gasket is definitely compressed for the 7/8" that is fully around the pipe and it's definitely sitting in the bottom of the drain assembly. A 48 hour flood test did not show any signs of leaking. I can also visually view the bottom of the p trap to see no leaks, but cannot access it without pulling up the pan. Thanks for any assistance.

That looks like it will seal.
You may also be able to pull the PVC pipe up a bit higher using a cat claw inside to grip and pull upward on it.

Thanks for the reply!

Since it's not compressed to the top, it looks like there might be a tiny bit of water that sits along the edge in between the rubber and the metal.

I was thinking to run a bead of Silicone around this so there won't be stagnant water in this small crevice. Any reason this would be a bad idea?

A bead of Silicone won't hurt anything.

Thanks, Terry you've been a big help.
