The answer to 'difference between PVC pipe and cast iron pipe' is that PVC (polyvinyl chloride) pipe and cast iron pipe are two common types of plumbing pipes used in residential and commercial buildings, but they have distinct features, benefits, and use cases. PVC pipe is a lightweight, corrosion-resistant, and affordable option that is widely used for water supply, drainage, and sewer lines. Cast iron pipe, on the other hand, is a heavier, more durable material that is often used for older buildings or in applications where higher strength and resistance to impact are required.
PVC pipe is generally easier to install and requires fewer specialized tools, making it a popular choice for DIY projects and renovations. Cast iron pipe, however, is more resistant to high temperatures and can withstand greater pressure, making it a better choice for certain commercial and industrial applications. Additionally, cast iron pipe is known for its longevity, with a lifespan of up to 100 years, while PVC pipe typically lasts 50-70 years.
