Need Help Extending Toilet Drain Pipe to Raise Flange Up to New Floor Level
Here's the situation:
I am remodeling my upstairs bathroom and will be laying new porcelain tile down on the floor. To prepare, I tore out the existing ceramic tile and a 1-inch layer of cement mud. I've got it all cleaned out down to the plywood subfloor. I plan to build up the floor with 1/2 plywood, 1/4 Wonderboard, and 3/8 porcelain tiles.
Here's the weird thing about the closet flanges. The flange that the toilet was connected to was imbedded in the tiles and cement mud layer. It was not glued to the PVC pipes below. It was simply resting inside a second flange that is screwed into the bottom plywood sub floor. So when I tore out the floor and chipped the cement away from the around the flange, I discovered the second flange below. The top flange was screwed into the cement layer with 6 rusty and breaking screws. So I took it out.
Now here is my challenge:
I want to remove the flange in the plywood subfloor and glue in a length of PVC pipe to bring the new flange up to the level of the tiles that I plan to install. I've been told that I should cut out the old flange, glue in a length of PVC pipe higher than I need, then put the floor in around the pipe, cut the pipe off to the approriate height, and glue in a closet flange on top of the tiles. I understand the concept of doing this, but I have never worked with PVC in this way before. I am very handy and I have a dremel tool that could possibly help with cutting out the old flange.
What exactly do I need to do to:
1. Cut off the old flange
2. Install a longer 3 inch pipe
3. Install a new flange on the top of th tiles

Thanks.
