When it comes to plumbing in homes, PVC and ABS pipes are two commonly used materials. While both are plastic pipes, there are some key differences between the two that homeowners should be aware of.
PVC (polyvinyl chloride) pipe is a white or gray pipe made from a type of plastic. It is commonly used for drainage and venting systems, as well as for cold water supply lines. PVC pipes are lightweight and easy to install, making them a popular choice for DIY plumbing projects. They are also relatively inexpensive, which makes them a cost-effective option for homeowners.
ABS (acrylonitrile-butadiene-styrene) pipe is a black pipe made from a type of plastic that is similar to PVC. It is commonly used for drainage and venting systems, but can also be used for waste and sewer lines. ABS pipes are known for their durability and resistance to impact, making them a good choice for underground applications.
One of the main differences between PVC and ABS pipes is their temperature rating. PVC pipes are rated for temperatures up to 140 degrees Fahrenheit, while ABS pipes are rated for temperatures up to 180 degrees Fahrenheit. This makes ABS pipes a better choice for hot water supply lines.
Another difference is their chemical resistance. PVC pipes are resistant to most chemicals, but are not recommended for use with gasoline, oil, or any other petroleum-based products. ABS pipes, on the other hand, are resistant to a wider range of chemicals, including petroleum-based products.
In addition, there are differences in their installation requirements. PVC pipes require primer and glue to join them together, while ABS pipes require a special cement. PVC pipes also require special fittings for changes in direction, while ABS pipes can be bent to make turns.
Overall, both PVC and ABS pipes have their advantages and disadvantages. Homeowners should consider the specific needs of their plumbing system when deciding which type of pipe to use. Consulting with a professional plumber can also help ensure that the right pipe is chosen and installed correctly.
