PVC vs ABS Pipe: Which Drain Pipe Should You Use?

PVC and ABS pipe do the same drain, waste, and vent job, so the choice usually comes down to local code: PVC is white and needs primer, ABS is black and does not.

Is PVC or ABS pipe better for drain, waste, and vent lines?

Neither is universally better. Both PVC and ABS are code-recognized plastics for drain, waste, and vent (DWV) lines, and they perform the same core job of carrying wastewater and venting the system. The deciding factors are what your local code allows, the color and joining method you prefer, and whether cold-weather impact resistance or noise control matters more on your project.

If you are still mapping out which materials go where in a house, our overview of the types of plumbing pipes covers supply and drain lines together, and our sewer pipe materials guide handles the buried line out to the main.

What is PVC pipe?

PVC (polyvinyl chloride) is a rigid white plastic pipe used widely for drain, waste, and vent lines, and in other schedules for cold water and irrigation. In DWV form it is made to ASTM D2665 and joined with a two-step solvent weld: purple primer to prep the surface, then PVC cement per ASTM D2564. It is the most commonly stocked drain plastic across much of the United States.

PVC also comes in pressure-rated grades (Schedule 40 and 80) for cold water supply, which is a different application from drain work. For the full schedule and sizing breakdown, see our guide to PVC pipe schedules and sizes.

What is ABS pipe?

ABS (acrylonitrile butadiene styrene) is a rigid black plastic pipe used almost entirely for drain, waste, and vent lines. It is made to ASTM D2661 and joins in a single step: one application of ABS cement with no separate primer, which makes assembly faster. Its standout trait is toughness in cold, so it resists cracking on freezing job sites and under rough handling.

ABS is the traditional drain plastic in many colder and western regions, while other areas standardized on PVC decades ago. That regional split is why the material you see in an existing home often reflects local code history more than performance.

PVC vs ABS pipe: how do they compare head-to-head?

Across the traits that matter for a drain line, PVC wins on noise control and wide availability, while ABS wins on cold-weather impact resistance and one-step assembly. On temperature rating and code standing the two are effectively tied. The table below lays out each factor side by side.

Which handles temperature, cold, and impact better?

On temperature, they tie: both PVC and ABS DWV pipe are rated for non-pressure use up to 140F, per Charlotte Pipe. That covers hot dishwater and laundry discharge. Neither is made for pressurized hot water; that job goes to CPVC, rated near 200F, which is why hot water supply uses a different plastic entirely.

The real split is cold and impact. ABS keeps more of its impact strength at low temperatures, so it resists cracking when handled on a freezing job site. PVC grows more brittle as it cools. In warm indoor conditions both are plenty tough, so this matters most for exposed or cold-region installs. Before settling on plastic for that cold run, weigh how cast iron compares to pvc on noise and fire safety too. For material decisions that extend beyond drain lines, choosing between PEX and PVC covers supply-line questions, and once you’ve picked your plastic, gluing PVC joints properly is worth reviewing.

Is PVC or ABS quieter, and which holds up outdoors?

PVC is generally quieter. It transmits less of the sound of draining water than ABS, which is one reason many builders route PVC stacks through finished living space. The gap is modest and can be closed on either material by wrapping or insulating the pipe where it passes behind walls.

Outdoors, both degrade under prolonged UV. Manufacturers advise coating exposed DWV pipe with a light-colored latex or acrylic paint that is compatible with the plastic. ABS can also soften or deform under sustained direct sun and heat, so long outdoor runs of either material need protection or a different pipe choice.

Which does the plumbing code allow, PVC or ABS?

Both PVC (D2665) and ABS (D2661) are listed as acceptable DWV materials in the International Plumbing Code and the Uniform Plumbing Code, but adoption is local. Many jurisdictions allow only one of the two for new drain work, and some restrict material by application. Confirm what your city or county accepts before you buy, because using a disallowed material can fail inspection.

Fittings must match the pipe material and standard, so an ABS system uses ABS fittings and a PVC system uses PVC fittings. Our guide to plumbing fittings by material covers how elbows, tees, and couplings are keyed to each pipe type.

When should you use PVC vs ABS?

Use whichever your local code accepts first; that often settles it. If both are allowed, lean PVC when noise control inside living space matters or when it is cheaper and better stocked near you. Lean ABS when you want faster one-step joints or you are working in cold conditions where impact resistance counts.

For most homeowners doing a small repair, the practical move is to match the existing drain material in the house so fittings and cement stay consistent. Mixing materials introduces the transition-joint issue covered next.

Can you join PVC and ABS pipe together?

Not with ordinary cement. PVC cement and ABS cement are chemically incompatible, so a glued cross-material joint looks finished but has almost no real bond and can pull apart or leak. This is one of the most common DIY drain mistakes, and it often passes a visual check before it fails.

The correct fixes are two. Use an approved mechanical transition coupling, a rubber shielded coupling with a stainless band that clamps the two pipes together, or use a listed ABS-to-PVC transition cement formulated to ASTM D3138. Many inspectors prefer the mechanical coupling, and some jurisdictions require it, so confirm local code before choosing.
