Cast iron soil pipe is used for drainage and waste removal in plumbing systems. It is durable and can withstand high pressure and heavy loads, making it ideal for use in commercial and industrial buildings. It is also commonly used in residential buildings for main sewer lines and vent stacks.
Cast iron soil pipe is still used in some construction projects, but it has become less common in recent years due to the rise of alternative materials such as PVC and ABS. Cast iron soil pipe is known for its durability and longevity, but it is also heavier and more expensive than other options.
Cast iron is used for pipe fittings because it is strong, durable, and can withstand high pressure and heat. It is also resistant to corrosion and can last for many years without needing to be replaced. Additionally, cast iron is easy to cast and shape into various fittings, making it a popular choice for plumbing systems.
Cast iron sewer pipes were commonly used until the 1960s, when PVC (polyvinyl chloride) pipes became more popular due to their lower cost and easier installation. However, some areas may still have cast iron pipes in use today.
Connecting plastic soil pipe to cast iron soil pipe requires a special connector called a Fernco coupling. The Fernco coupling is a rubber sleeve with stainless steel clamps on either end that can be tightened to create a secure connection between the two pipes. Simply slide the Fernco coupling onto the end of the plastic pipe and tighten the clamps around the cast iron pipe to create a watertight seal.
