09Drains & Closet Flanges

Oatey offers three styles of repair flanges for this application.  The first is the No-Caulk cast iron repair flange which comes in two depths. Once the old flange is removed and cast iron pipe is cleaned off, these flanges will slide over the vertical cast iron drain pipe. The flat side of the gasket should be facing down and resting on the inside bottom lip of the flange. Tightening the four bolts in even rotation will compress the gasket against the outside of the pipe, and create a water tight seal. Remember that the bottom of the flange must be set on top of the finished flooring, and then screwed into the subfloor. The second is our PVC or ABS Twist-N-Set repair flange which inserts into the vertical cast iron drain pipe after the old flange is removed. The gasket tightens as the flange is turned in a clockwise rotation. Remember that the bottom of the flange must be set on top of the finished flooring, and then screwed into the subfloor. The third option is the PVC or ABS Replacement closet repair flange which also inserts into the vertical cast iron drain pipe after the old flange is removed. This flange is sealed by the tightening of three stainless steel bolts in even rotation. This compresses the gasket between the outside of the flange tail piece, and the inside of the cast iron drain. Remember that the bottom of the flange must be set on top of the finished flooring, and then screwed into the subfloor. All flanges must be screwed into the subfloor before setting the toilet bowl into place, this sometimes will require drilling pilot holes through the finished flooring.

The easiest way to remove the strainer is to weave a string or small wire through two openings near the edge of the strainer and pull straight up. It is not recommended that you pry the corner up because it could damage the shower base surface. When you are ready to reinstall the strainer, simply line it up over the drain body and press down evenly.
