For what plumbing purposes can cast iron pipe be used?

Cast iron pipe is an incredibly versatile material in plumbing systems due to its strength, durability, and resistance to corrosion. It is commonly used for various plumbing purposes.

For above-ground applications, cast iron is particularly suited for drainage, waste, and vent systems because it can handle high volumes of wastewater and harsh waste products without degrading over time. Its ability to dampen sound also makes it ideal for plumbing systems within buildings, reducing noise from running water and waste.

When considering underground applications, cast iron pipe can also be used for building drains. It is buried underground and supports the system that collects wastewater from toilets, sinks, and other fixtures, channeling it to the city sewer system or a septic tank. Its weight and robustness enable it to withstand the pressure of the soil and any dynamic loads from above, like traffic.

Lastly, while not as common, cast iron can also be used for underground water supply lines. Although materials like PVC or copper are more frequently chosen for this purpose due to cost and weight advantages, cast iron provides an alternative where durability and longevity are paramount, as it can resist the erosion that might otherwise compromise the integrity of water supply lines.

The collective applicability of cast iron pipe across these different plumbing scenarios demonstrates its unique qualities and confirms that
