What is ABS pipe?

ABS pipe is plastic pipe made from acrylonitrile-butadiene-styrene resin for drain, waste and vent applications. PPFA’s ABS Specification Sheet identifies it as Schedule 40, which describes wall thickness. For a home drainage job, ask which pipe construction is proposed and whether the planned hot or chemical discharge fits its limits.

What this means for your home project

  1. Ask the plumber to identify whether the proposed ABS pipe is solid wall or cellular core; PPFA lists both constructions. Source: Plastic Pipe and Fittings Association, read 2026-10-31.
  2. For continuous hot drainage, ask how the planned discharge fits PPFA’s recommended maximum of 140°F. Source: Plastic Pipe and Fittings Association, read 2026-10-31.
  3. Before discharging a specific chemical, request the pipe manufacturer’s compatibility guidance for that chemical. Source: Plastic Pipe and Fittings Association, read 2026-10-31.
  4. For an underground drain, ask how the installation will account for soil and surface loads; PPFA’s statement depends on proper installation. Source: Plastic Pipe and Fittings Association, read 2026-10-31.

Can ABS piping be used for underground DWV applications?

PPFA describes ABS as suitable below ground when properly installed. Its Schedule 40 specification also identifies both above-grade and below-grade use. “ABS pipe when properly installed, can withstand loads of soil, under slab foundations and high surface loads without collapse, cracking or denting.” Source: Plastic Pipe and Fittings Association, read 2026-10-31. “The pipe can also be installed above or below grade.” Source: Plastic Pipe and Fittings Association, read 2026-10-31.

What is ABS pipe according to the pipe trade association?

PPFA defines ABS by its thermoplastic resin. The NBS report explains that DWV includes sanitary drainage and vent piping inside the building. “ABS pipe and fittings are made from a thermoplastic resin called Acrylonitrile-Butadiene-Styrene (or ABS for short).” Source: Plastic Pipe and Fittings Association, read 2026-10-31. “DWV Systems : The drain-waste-vent system, includes all the sanitary drainage and vent piping inside the building or relevant portion thereof, and includes the building drain to its point of connection with the building sewer.” Source: National Bureau of Standards, read 2026-10-31.

What kind of chemical resistance does ABS pipe provide?

PPFA describes chemical resistance in many applications. Its specification directs chemical-specific decisions to the pipe manufacturer rather than treating ABS as universally resistant. “ABS pipe offers excellent chemical resistance in many applications.” Source: Plastic Pipe and Fittings Association, read 2026-10-31. “Contact the pipe manufacturer for a detailed list of chemicals that can be satisfactorily discharged through ABS pipe.” Source: Plastic Pipe and Fittings Association, read 2026-10-31.

Will hot water damage ABS systems?

PPFA’s 2024 specification recommends a maximum of 140°F for continuous drainage. Use that stated application limit when discussing hot discharges with the plumber. “The recommended maximum temperature for continuous drainage applications is 140°F.” Source: Plastic Pipe and Fittings Association, read 2026-10-31.

Will ABS pipe rust or corrode?

PPFA’s technical guide says ABS does not rust or corrode. This describes the pipe material; its underground application statement separately depends on proper installation. “ABS pipe does not rot, rust, corrode or collect waste.” Source: Plastic Pipe and Fittings Association, read 2026-10-31.
