ABS DWV Pipe & Fittings

ABS DWV pipe and fittings are designed for drain, waste, and vent plumbing in residential and commercial projects. Made from acrylonitrile butadiene styrene, this black plastic system is light, impact‑resistant, and quick to assemble with one‑step solvent cement. Installers appreciate faster work, fewer leaks, and consistent performance in cold weather.

Choose from elbows, tees, wyes, sanitary tees, long‑sweep bends, traps, cleanouts, couplings, adapters, caps, and closet bends across common DWV sizes from 1‑1/2 in. to 6 in. (and larger for mains). Products generally meet ASTM D2661 for pipe and ASTM D3311 for fittings, with options that carry CSA and NSF markings for code‑driven jobs. ABS is intended for non‑pressure drainage and venting, not potable water or compressed air.

Key advantages include corrosion resistance against household chemicals, smooth interiors that reduce clogging, and stable joints that don’t require primer. Compared with PVC, ABS often handles low temperatures and jobsite impacts better, helping rough‑in schedules stay on track.

Practical tips for success:
- Dry‑fit first and mark alignment before cementing.
- Cut square, then deburr and bevel for full‑depth sockets.
- Use manufacturer‑approved ABS cement; observe set and cure times by temperature.
- Maintain proper slope (typically 1/4 in. per foot on horizontals) and support spacing.
- Isolate noise by wrapping stacks or using resilient clamps where desired.
- For transitions between ABS and PVC, use a listed transition cement or a shielded, code‑approved coupling, and always confirm local requirements.

Whether you’re running a new bathroom group, adding a cleanout, or replacing aging drains, ABS DWV pipe and fittings deliver reliable flow and simple, scalable installation. Stock the right assortment and a quality cutter, brush, and cement to keep your plumbing builds clean, fast, and code‑compliant. Many suppliers also offer fire‑stopping accessories, test plugs, and hangers to streamline inspections and support your installs.
