Sealing Black water tank

Hello Group,
I Plan to install composting toilet. The original toilet is removed, need to remove toilet flange and seal so I continue installing bamboo flooring. How is the flange removed? Bolts were drilled but can not seem to pry flange loose. ??
Thanks Carolyn

You don't need to remove the flange. Just get a stopper to screw into it. The composting toilet sits on top of it.

You can then combine the old black tank and the existing grey tank into one huge grey tank. We did the same thing and it has made a huge difference to our ability to stay without services. Best upgrade ever.

They usually screw into the tank. With 2 hands ( opposite sides) grab from bottom to top of the flange pipe going into the tank and try to twist counter clockwise.

thank you!!

Thank you,
The flange was glued in. I wanted to relocate the toilet so I ended up cutting off flange with a Dremel
