For what plumbing purpose can ABS plastic pipe be used?

ABS plastic pipe is specifically recognized for its effectiveness in above-ground drainage, waste, and vent applications. This type of pipe is designed to handle the conditions typically found in drainage systems, including the transport of wastewater. ABS is lightweight, easy to work with, and has excellent resistance to impact and chemicals, making it suitable for the various stresses it encounters in a drainage system.

Other uses like hot water supply (A) are not appropriate for ABS because it does not withstand high temperatures as effectively as other materials, such as CPVC or PEX. While ABS may occasionally be thought of in discussions of PVC drainage (C), it is not used as a direct replacement. Similarly, ABS is not suitable for gas distribution (D), where materials specifically rated for gas service, like CSST (corrugated stainless steel tubing) or black pipe, are required to ensure safety and compliance with standards. Thus, the designation of ABS for above-ground drain, waste, and vent purposes aligns with its engineered properties and intended applications in plumbing.
