Question

Polyvinyl chloride is used for drain pipes in plumbing applications. It has replaced traditional cast iron pipe for this purpose. The major advantage of PVC in replacing cast iron for this application (particularly if you are a plumber or homeowner) is that PVC?

1) is of lighter weight.
2) is easier to handle and cut.
3) is more resistant to corrosion.
4) All of the above are advantages of PVC.

Answer 1

PVC is preferred over cast iron for plumbing because it is lightweight, easy to handle and cut, and resistant to corrosion, representing all listed advantages.

Step-by-step explanation:

The major advantage of using Polyvinyl Chloride (PVC) over traditional cast iron for drain pipes in plumbing applications is all of the above advantages. PVC is indeed of lighter weight, which makes it easier to carry and work with for plumbers and reduces the overall load on supporting structures. It is also easier to handle and cut, allowing for quicker installations and modifications. Moreover, PVC is highly resistant to corrosion, which extends the lifespan of the pipes and reduces long-term maintenance costs. These benefits have led to PVC being one of the world's most widely used polymers, especially in construction materials.
