Which material is commonly used in RV plumbing due to its durability?

The use of ABS plastic in RV plumbing systems is favored primarily due to its excellent durability and resistance to impact and cracking. ABS, or acrylonitrile butadiene styrene, is a thermoplastic that offers a combination of strength and flexibility, which makes it ideal for the demanding conditions often found in recreational vehicles. It is also lightweight, which is an essential factor in RV design to minimize overall weight and enhance fuel efficiency.

Additionally, ABS plastic is resistant to many chemicals and can handle a range of temperatures, making it suitable for handling wastewater and various fluids commonly encountered in RV plumbing. Its ease of installation, as it can be quickly glued together without the need for complicated tools or fittings, adds to its popularity in the RV industry.

While other materials like steel and copper also have their advantages, they tend to be heavier and can corrode over time, making them less ideal for the specific requirements of RV plumbing. PVC, on the other hand, is also a popular choice but is not as impact-resistant as ABS plastic, making it less durable in certain conditions.
