I Am Trying To Remove The Fiberglass Floor Pan.the Floor Drain Has A Metal Collor That Is Leaded Around The Pvc Drain Pipe.I Have Tried To Pry It Out But It Will Not Budge.do I Drill Out The Lead Or What?

To remove a poured lead and oakum joint take a 3/8" drill bit and drill a few holes down past the lead and into the oakum.. Push a screwdriver under the lead ring and lever it up. Once it's free you can began to peel the lead ring out. Now pick out the oakum and you can pull the joint apart. Good luck, Tom

Put a rag in the drain so nothing falls in.
