What type of piping is typically used for exterior above-ground applications?

For exterior above-ground applications, CPVC or galvanized steel is typically chosen due to their durability and resistance to environmental factors.

CPVC (Chlorinated Polyvinyl Chloride) is particularly advantageous because it offers a high level of resistance to temperature changes and is more flexible than standard PVC, making it suitable for a variety of applications including those exposed to direct sunlight or varying weather conditions. Its ability to withstand higher temperatures and pressures also makes it a strong contender for exterior installations.

Galvanized steel, coated with a layer of zinc to prevent rust, is another robust option for above-ground use. Its strength and resistance to impacts make it ideal for structural applications where additional support is necessary. Although it can be subject to rust over time if the coating is damaged, proper care and installation can mitigate these risks.

Other materials, while they may have their own benefits in specific contexts, are less frequently chosen for exterior above-ground plumbing due to their limitations. PVC, while lightweight and corrosion-resistant, is vulnerable to UV degradation and may become brittle over time when exposed to sunlight. Copper is highly durable and has antimicrobial properties, but it is subject to weathering and can be costly in large-scale applications. Cast iron, while extremely durable and often used for drainage
