Hello, I realized as I was installing the subfloor in my new bathroom that I had cut off the pvc to short. It is slightly lower that the subfloor.
Is there a longer flange which will solve this problem or should I remove the floor add a coupling and more pvc to raise the height?

Thanks,

"Is there a longer flange which will solve this problem?"

Yes there is. It's called a "deep flange", (see image) this is simply a closet flange with a longer collar. No need to rear the floor up. Good luck, Tom
