Cast Iron and PVC Comparison

Cast iron plumbing is a true method that has withstood the test of time. Having been used since the 16th century, it is safe to say that durability is one of its strengths. Like other metallic and steel products, they are prone to rust and therefore require regular maintenance. On the other hand, PVC is also considered durable in its own right and is not affected by rust since it is made from plastic. Here are other factors that differentiate cast iron pipes and PVC pipes:

• Adjustability

As technology advances, modern cast iron has become surprisingly more adjustable. Unlike the previous cast-iron pipes, today, plumbers can adjust the fittings even after installation and orient the lines accordingly. This is one of the main reasons cast iron pipes are preferred, not to mention home remodeling is made easier. Despite being made from plastic, PVC can’t be adjusted after the installation of the lines. This makes remodeling difficult since sections of the plumbing must be replaced whenever changes are needed.

• Price

When it comes to price, definitely cast iron will be expensive compared to plastic PVC lines. PVC fittings and pipes can cost up to 50% less than cast iron lines. Since they are lighter, plumbers find them easy to install compared to cast iron pipes. If you are looking for something easier on the wallet, then PVC is the way to go. However, depending on your plumbing needs, we can help you make a suitable decision since not all plumbing systems require PVC.

• Fire Resistance

Whether your plumbing uses PVC lines or cast iron pipes, fires are not a major concern since they are both resistant to fire. However, cast iron is more resistant and can’t melt even when exposed to extreme temperatures. This is not the case for PVC pipes since temperatures above 450 degrees result in melting. PVC lines are likely to be destroyed in case of a house fire, but cast iron will remain intact. If you are more susceptible to fires, it is advisable to consult a professional plumber for pipe replacement.

Although PVC lacks a long, rich history like cast iron, it has been used for more than half a century to great success. We recommend PVC for residential sewer lines because of its consistent flow rates, attractive price, and overall durability. If you are looking for a heavy-duty pipe that will comply with strict fire mitigation regulations, cast iron pipes are a great choice.
