- Checking the code
Why is ABS pipe prohibited? This sounds like a familiar question and it will be answered in this part.

Still, those people must adhere to the regulations.
Only one thing would make you choose PVC over ABS. Although there’s more strength in ABS, it contains BPA or Bisphenol-A. This chemical is also present in plastic containers filled with water or food but it contains toxicity. BPA is not harmful to humans but it is among animals. Based on some studies, it can cause damage to their cardio, hormonal, and neurological systems.
However, The Food and Drug Association reversed its identification of BPA. As of the moment, it’s labeled as safe on some levels when found in food containers.
- The real strength
ABS is deemed stronger than PVC due to its resistance to shock. So, it seems that it has the edge over PVC as it needs to bear the weight of the toilet. You shouldn’t forget that a toilet flange is usually concealed from sight. Hence, plumbers search for other qualities. ABS can be more appealing as it can withstand cold temperatures. Nothing’s perfect so it has weaknesses too.
ABS is not tolerant of direct sunlight and how much more heat? PVC is not invincible to fire. It also melts since it’s plastic but it doesn’t release harmful fumes like ABS. PVC can also hinder the sound of water flowing.
- What’s More Common
The utilization of PVC and ABS are mainly regional so you can say that it’s safe for sewer. Houses built in the 80s are equipped with toilet flanges made of either of these two materials. But the majority of toilet flanges are made of PVC with cast iron, brass ring, or stamped steel.
Aside from weight, there’s no difference in the cost of ABS and PVC toilet flanges. It only varies from place to place. Delivery fees can add up to the cost as well.
Wrapping it Up!
You’ll only find a little difference between ABS vs PVC toilet flange since they’re both plastics. ABS can withstand shock and low temperatures but there are safety issues. Some studies show that it can harm animals, which may be the reason why PVC toilet flanges have been commonly used since the eighties. This material is flexible and can minimize the noise of water flow.
