How well do you know your pipe flanges? Remember that flanges come in a variety of shapes and sizes to suit different applications. A flange is usually in the shape of a disc and is used to connect two tubes together or to connect a pipe to a valve, tee, choke or other component. Providing support and strength, two flanges are typically attached to pipe ends with a gasket in between.
Remove the existing flange by unscrewing the anchor screws and prying the flange out of the pipe. Place a scrap piece of drain pipe of the same size as the existing drain pipe on top of the existing drain pipe. You can measure the inner diameter of the existing pipe to determine the proper size.ress the new flange into the drain pipe opening. Position the flange so that the marks on the left and right line up with the ends of the channels in the flange. Mark the position of the screw holes. Remove the flange. Drill pilot holes using the masonry drill bit included with the cement anchors and a hammer drill.
