What is one primary reason plastic pipes are popular in residential plumbing?

Plastic pipes are popular in residential plumbing primarily because they are cost-effective and lightweight. The lightweight nature of plastic makes them easier to handle and install, reducing labor costs and time on the job. Additionally, plastic pipes often have lower material costs compared to metal pipes, making them an economical choice for homeowners and builders alike.

The cost-effectiveness is attributed to both the materials used and the ease of installation, which can lead to significant savings in both project budgets and overall plumbing system efficiency. Plastic pipes also exhibit excellent resistance to corrosion and scale, which enhances their longevity and reduces the need for frequent replacements, further contributing to their appeal in residential applications.
