Step 5 · Remove PVC/ABS Flange

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

A PVC or ABS flange is solvent-welded (glued) to the drain pipe, so it must be cut out. The safest and most professional method is to use a special drill bit called an inside pipe cutter or flange cutter. Attach the bit to your drill. Carefully lower the cutter into the flange until the cutting edge is positioned just below the bottom of the flange hub, inside the drain pipe. Ensure it is level. Start the drill slowly and apply steady, even pressure, allowing the cutter to slice through the pipe from the inside out. Once the cut is complete, the flange will be free from the drain pipe and can be lifted away. Be extremely careful not to cut too low, as this will shorten the drain pipe and complicate the new installation.
