Do Plumbers Still Use Cast Iron Pipes?

Cast iron pipes have been a staple in plumbing systems for over a century, but how relevant are they in today's modern plumbing practices? The answer is complex, with various factors influencing their continued use.

The Decline of Cast Iron Pipes

No PVC has not been used for over 30 years. While the age of cast iron pipes may make them seem like relics of the past, it's important to understand that they are not entirely phased out by modern plumbing materials. No PVC cast iron has not been used for over 30 years.

Despite the passage of time, you can still buy new cast iron pipes, even if it was last checked years ago. However, when plumbers encounter the need for repair or replacement, plastic pipes are typically the go-to material. But when it needs repair or replacement plumbers these days usually go back with plastic pipes.

Areas of Continued Use

While cast iron pipes may no longer be the primary choice for new installations, they still hold a place in certain applications. For instance, they are commonly used in drain lines for dishwashing machines in hotels and restaurants, where their durability and longevity are highly valued. In some other settings, such as kitchen and bathroom sinks, cast iron pipes are still used due to their inherent acoustic insulation properties and resistance to corrosion.

The Role of Plumbing Codes

Despite the decline in use, cast iron pipes still have a place in specific code situations. In certain jurisdictions, cast iron pipes are actually required. Certain code situations call for C.I. This requirement is driven by factors such as their durability, resistance to common plumbing issues, and compliance with building codes in commercial and industrial settings.

Common Uses and Benefits

Even when not required by code, many plumbers choose to use cast iron pipes in various applications, often due to their unique benefits. For example, they are frequently used in the existing DWV (Drain, Waste, and Vent) piping in homes and commercial buildings. Short lengths of cast iron are preferred in these instances because they require less cutting and can be installed quickly without causing major disruptions to the system.

Additionally, cast iron pipes are favored in sections beneath toilets, particularly for their acoustic insulation properties. Cast iron deadens the sound of a toilet flush much more effectively than ABS (Acrylonitrile Butadiene Styrene) or PVC (Polyvinyl Chloride) pipes, providing peace of mind for households concerned about noise pollution. CI deadens the sound of a toilet flush much more than ABS or PVC so everyone else in the household doesn’t hear what you just did.

Challenges and Considerations

While cast iron pipes offer significant advantages, they also come with certain challenges. Maintenance and repair of cast iron pipes can be more time-consuming and costly compared to their plastic counterparts. However, their longevity and resistance to corrosion mean that, in the long run, they can be more cost-effective.

Conclusion

In summary, yes, plumbers still use cast iron pipes in various applications, but their use has significantly declined in the face of more modern materials. Their continued use is driven by factors such as acoustic insulation, durability, and compliance with certain plumbing codes. While they are not the default choice for new installations, their unique benefits make them a valuable tool in the plumber's arsenal.
