When it comes to plastic piping for residential or commercial plumbing, the debate of ABS vs PVC often comes up. Understanding the difference between ABS and PVC pipe can help you choose the right materials for your plumbing system, whether you’re working on a new kitchen plumbing sink, upgrading a toilet flange, or installing a drainage system.
Both ABS (Acrylonitrile Butadiene Styrene) and PVC (Polyvinyl Chloride) pipes are widely used in the plumbing industry. Each has unique advantages and limitations. In this guide, we’ll break down ABS plastic pipe vs PVC so you can confidently decide which is best for your project.
ABS Pipe vs PVC Pipe: Appearance, Composition & Usage
The most noticeable difference between black and white PVC pipe is—no surprise—their color. ABS pipes are black, while PVC pipes are typically white. You may have seen black PVC pipes under your sink or sticking out of your exterior wall; these are usually ABS drain pipes or ABS sewer pipes. Meanwhile, white pipes are commonly PVC toilet flanges, white drain pipes, or PVC kitchen sink drain pipes.
But color isn’t the only thing that sets them apart. Here are the key technical differences between ABS pipe vs PVC pipe:
1. BPA Content and Health Concerns
- ABS plastic contains BPA (Bisphenol A), a chemical used to harden plastic. It’s found in many plastic materials, including water bottles and food containers.
- PVC plastic pipes, in contrast, are BPA-free.
While the FDA considers BPA safe at low levels, many homeowners prefer to avoid it entirely. If that’s a concern for you, PVC versus ABS might come down to health preference.
2. Strength, Flexibility & Temperature Tolerance
- ABS pipes are stronger and more impact-resistant. They hold up better in freezing conditions, making them ideal for underground sewer lines or cold-climate installations.
- PVC pipes are more flexible and better at absorbing sound, reducing the noise of running water in your walls.
- However, ABS plastic pipe can warp in direct sunlight, whereas PVC handles UV exposure slightly better (but still needs protection).
The temperature difference between ABS and PVC pipe performance is critical—ABS pipe temperature rating is higher in cold environments, while PVC is more stable under long-term UV exposure.
Working with ABS and PVC: Installation and Maintenance
The way you install black ABS pipe vs white PVC pipe differs, too. This affects the labor cost and long-term maintenance of your plumbing system.
1. Gluing and Bonding
- ABS piping requires a one-step process using a special ABS cement—no primer needed. This makes installation faster and cleaner.
- PVC pipe, however, must be primed first (typically with a purple primer) before applying PVC cement. This two-step process adds time and mess to the job.
Many plumbers find ABS pipework easier to work with, especially for large jobs involving ABS drain systems, ABS closet flanges, or black flexible drain pipes.
Pro Tip: Never use ABS glue for PVC or vice versa. The chemicals are not cross-compatible. If you’re connecting ABS to PVC, always use an approved transition cement.
2. Code Compliance
Local plumbing codes may dictate whether you use ABS or PVC plumbing in your project. Some cities require PVC piping for drain lines, and others allow both. Always check your local building code before purchasing plastic piping.
Cost Comparison: Is ABS or PVC More Affordable?
In general, PVC vs ABS price is similar, though PVC might be slightly cheaper per foot. However, labor costs can tilt the scales. Since ABS plastic pipes are installed quicker (no primer needed), they can be more cost-effective despite a higher material price.
Shipping costs also vary: ABS is typically heavier than PVC, so prices may fluctuate depending on the supplier and distance.
ABS vs PVC for Specific Applications
| Application | Preferred Pipe | Why? |
|---|---|---|
| Kitchen Sink Drain | PVC | Quieter and flexible, fits tight spaces |
| Underground Sewer Line | ABS | Stronger and cold-resistant |
| Sunlight Exposure | PVC | Less likely to warp under UV |
| Fast Installation | ABS | No primer needed |
| Low Noise in Walls | PVC | Quieter operation |
| Cold Climates | ABS | Handles low temps better |
What Is Black PVC Pipe Called?
Black pipes in your plumbing system are often referred to as ABS pipes or sometimes black PVC for simplicity. The official term is Acrylonitrile Butadiene Styrene pipe, and it’s typically used for drain, waste, and vent (DWV) systems.
You might see:
- 2-inch black PVC pipe
- 3 inch ABS pipe
- 4 inch ABS pipe
- Black PVC connectors
- ABS shower drains
- ABS sanitary lines
These sizes and fittings are common in residential construction, especially for black plastic drain pipes or under-the-sink assemblies.
