Homeowners often face an important choice when it comes to selecting plumbing materials: plastic or metal pipes. Plastic pipes, such as PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), and ABS (acrylonitrile butadiene styrene), have gained popularity due to their durability, affordability, and ease of installation compared to metal options. While PVC and ABS share many uses, the key difference lies in their composition.
This article dives deep into what ABS pipe is, how it compares to PVC, and where each material is best suited. By the end, you’ll have a clearer understanding of which type of pipe fits your plumbing needs.
Key Takeaways
- ABS (Acrylonitrile Butadiene Styrene): Durable, resistant to chemicals, and ideal for underground use but degrades in sunlight.
- PVC (Polyvinyl Chloride): Flexible, resistant to higher temperatures, and better for above-ground plumbing.
- Always consult local building codes before starting a plumbing project.
Plumbing 101
Understanding basic plumbing principles is essential before choosing materials for your system. Missteps can lead to leaks, water damage, or even legal trouble if the work doesn’t meet local codes.
DIY plumbing might seem tempting, but unless you have the skills and experience, it’s often best to call a licensed plumber. For homeowners in Everett, WA, Apollo Plumbing can be “your personal plumber,” offering expert advice and installation.
What Is ABS Pipe?
ABS, or acrylonitrile butadiene styrene, is a black plastic pipe commonly used for drainage, sewage, vents, and DWV (drain, waste, and vent) systems. Known for its strength and durability, ABS resists high temperatures and corrosion, making it a preferred choice for many industrial and residential applications.
Advantages of ABS Pipe
- High-Temperature Resistance: Performs well in environments with fluctuating temperatures.
- Chemical Resistance: Resistant to many chemicals, making it suitable for industrial uses.
- Durability: Rigid structure withstands pressure and stress better than some alternatives.
Disadvantages of ABS Pipe
- BPA Content: ABS contains BPA, which can raise health concerns, though levels in plumbing systems are generally considered safe.
- Sunlight Sensitivity: Prolonged exposure to sunlight causes the material to degrade, limiting its use in outdoor applications.
When to Use ABS
- Ideal for underground plumbing where sunlight exposure isn’t a concern.
- Effective in environments requiring chemical resistance.
What Is PVC Pipe?
PVC, or polyvinyl chloride, is a widely used plastic pipe known for its flexibility and versatility. It’s commonly employed in plumbing and drainage systems. Unlike ABS, PVC is typically white or light-colored, making it easy to identify.
Advantages of PVC Pipe
- Flexibility: Greater flexibility reduces the risk of cracks or breaks.
- Temperature Resistance: Performs better than ABS at higher temperatures.
- Lightweight: Easier to handle and install.
Disadvantages of PVC Pipe
- Limited Underground Use: Less durable for underground or industrial settings.
- Chemical Resistance: Lower resistance to certain chemicals compared to ABS.
When to Use PVC
- Best for above-ground indoor plumbing applications.
- Suitable for systems requiring flexibility and resistance to higher temperatures.
ABS vs. PVC: Key Differences
Appearance
- ABS: Black in color.
- PVC: White or light-colored.
Flexibility and Durability
- PVC: More flexible and less brittle.
- ABS: More rigid but durable under pressure.
Temperature and Sunlight Resistance
- ABS: Better for underground applications.
- PVC: Performs well in above-ground environments.
Connection Process
- ABS: One-step process using special cement.
- PVC: Two-step process requiring primer and cement.
Municipal Regulations
Always check local building codes before selecting a material. For example, some municipalities may restrict the use of ABS for indoor plumbing due to its BPA content.
BPA Content
While ABS contains BPA, the FDA considers its levels safe for use in systems like drainage and sewage. Still, BPA’s presence may influence your decision based on health considerations.
When to Choose ABS or PVC
- Choose ABS for underground plumbing, cooler environments, or areas requiring chemical resistance.
- Choose PVC for indoor plumbing and systems exposed to sunlight or high temperatures.
Always consult local building codes to ensure compliance. Often, either material works, and the decision comes down to the specific application.
Can ABS or PVC Be Used for Water Supply Lines?
ABS and PVC are not typically recommended for potable water lines unless they are underground and not exposed to heat or sunlight. For drinking water systems, materials like copper piping are better suited. Local regulations will provide guidance on approved materials.

FAQs
Before diving into FAQs, here’s a quick note: ABS pipes are a common choice for plumbing systems, but understanding their applications and limitations can help you make informed decisions.
Is ABS pipe safe for drinking water?
No, ABS is not typically used for potable water due to its BPA content.
Can ABS pipes be exposed to sunlight?
ABS pipes degrade under direct sunlight, so they are best suited for underground applications.
What is the lifespan of ABS pipe?
ABS pipes generally last 50 years, depending on environmental factors and proper installation.
How does ABS compare to metal pipes?
ABS is lighter, non-corrosive, easy to install, and generally doesn’t need to be insulated but it lacks the strength of metal pipes in certain applications.
Final Thoughts
Both ABS and PVC pipes are versatile, cost-effective options for plumbing systems, but their differences matter. ABS is better for underground use and environments requiring chemical resistance, while PVC excels in indoor, above-ground applications.
Always check local codes and consult professionals like Apollo Plumbing for expert guidance. Whether you’re repiping or starting a new project, choosing the right material ensures a durable and efficient plumbing system.
