Moving Basement Shower Drain

Toilet Flange

I'm currently drywalling my bathroom but I'm planning forward for installing the toilet. I'm going to be pouring some self levelling cement at some point and the toilet pipe and flange will be affected. So, I have a few questions;

1. How do I remove the flange (see picture). Is it just friction fitted to the pipe? Can I just pry it up? The pipe is cast.

2. What is the best method to extend the pipe just a half inch or so to gain the height that the self levelling cement will create? Should I just use one of those flange extensions. (see 2nd picture)

GoldMaple,

I hope you find your answer. I am going through a similar process (rebuild basement bathroom, moving shower drain) at the moment and your detailed pics have been very helpful. Also, if you have a link to the shower build pictures, I would sure love to see them!

Good luck,

Kent
