ABS and PVC are used in pipes because they are non-toxic and resistant to abrasion. ABS pipes are easier to install than PVC pipes but are more likely to deform when exposed to the sun. ABS stands for acrylonitrile butadiene styrene, and PVC stands for polyvinyl chloride.
Difference Between ABS Pipes and PVC Pipes
Many of the key differences between ABS and PVC are either minor or situational, but there’s one difference likely to stand out to many homeowners: ABS pipe is made with BPA, and PVC pipe is not.
BPA, or Bisphenol A, is a chemical commonly used to harden plastic. It is present in all sorts of plastic materials, including containers for food and water. While there is no evidence that BPA poses a risk to humans, animal studies show a growing range of concerns about possible hormonal, neurological, and cardiological effects, among other potential problems.
Some local building codes mandate the use of one type of pipe over the other for drainage, sewage, or other plumbing projects, though many leave the option up to plumbers and builders.

Applications of ABS Piping
ABS piping is a cost-effective choice for commercial and residential uses. It won’t flake, peel, rot, dissolve, fade, or leak (unless punctured). It’s an ideal choice for use outside, underground, in the extreme cold, and where it isn’t in direct sunlight. It’s often the choice of plumbers for use in drain, waste, and vent piping systems. You’ll also find that ABS pipe is frequently used in sewer systems for drainage and as electrical insulation.

Applications of PVC Pipes
PVC or polyvinyl chloride pipes have diverse applications because they are malleable, flexible, and can be used almost in all areas. PVC pipes are used in both commercial and residential sectors. The application of PVC pipes includes their use in plumbing, sewage and drainage systems, drinking water distribution, irrigation systems, chemical handling, fume, exhaust and ventilation ducts, and recreation purposes.
Regular schedule 40 PVC pipe is perfect for drains and wastewater. Like ABS, PVC pipe is used for drain, waste, and vent piping systems and as insulation for electrical cables. It’s versatile and durable and the choice for professionals and DIYers alike.

How to Join ABS and PVC Piping
It isn’t recommended that ABS and PVC be joined and used within the same piping system. In fact, many plumbing codes restrict ABS from being glued to PVC, so it’s important to check local codes before making an attempt to do so. However, if there aren’t any restrictions in your location, ABS and PVC pipes can be joined using fittings (such as the ones we carry) rather than glue.
When you’re joining an ABS pipe to a PVC pipe, it can’t be done with pipe cement or glue. Instead, the best method uses a rubber sleeve and metal jacket to clamp the connection. The sleeve is positioned over the ends of the two pipes to connect them. The metal sleeve is then used to clamp the rubber sleeve into place. Be sure that you are using a coupling designated as plastic-to-plastic.

When to Use ABS vs. PVC?
PVC and ABS pipes are useful in residential and commercial plumbing, but it’s important to know the differences to make the best decision about which one to use. ABS pipe is best used for underground situations, where it’s extremely cold, and in locations that are not exposed to direct sunlight. PVC, on the other hand, is ideal for indoor plumbing use because it’s soundproof.
Be sure that you check building codes before you decide which pipe to use. There are regulations in some areas that dictate the type of piping that has to be used for certain plumbing jobs.
