The closet flange fits onto the drain and is fused in place and then a wax ring sits on the top of the flange and provides a water tight connection with the toilet. In order to properly install this fitting, ABS cement is required to secure the closet flange to the existing pipe and also to create a strong connection for other pipes and fittings in the system. Unlike PVC, ASB fittings and pipe do not need a “primer” in order to soften the pipe and create a solvent weld. This will save you time as you fix or construct your plumbing system. ABS pipes and fittings are used in a wide variety of DWV (Drain, Waste and Vent) applications. It can also be installed above or below ground due to its ability to be resistant to most acids, salts and alkalis.
