The answer to 'PVC pipe vs cast iron pipe' is that PVC (polyvinyl chloride) and cast iron are two common types of pipe used in plumbing systems, each with its own advantages and disadvantages. PVC is a lightweight, corrosion-resistant, and affordable option that is easy to install, while cast iron is a heavier, more durable material that is often used in older homes and can last for decades.
PVC pipe is a popular choice for modern plumbing systems due to its low cost, ease of installation, and resistance to corrosion. It is commonly used for water supply lines, drain lines, and sewer lines. Cast iron, on the other hand, is a more traditional material that is known for its strength and longevity. It is often used in older homes and commercial buildings, and is particularly well-suited for drain and sewer lines where durability is important.
