Wear and tear is normal in residential pipe systems. One frequently asked question is “How long do cast iron drain pipes last?” Cast iron waste pipes last anywhere between 50 and 100 years.
Cast Iron: Cast iron pipes last between 80-100 years, and are built to withstand a high amount of water pressure. However, like galvanized steel, cast iron piping has been found to be susceptible to rust over time. PVC (Polyvinyl Chloride): Traditionally, PVC piping only lasts between 25-40 years.
Cast iron sewer pipes typically last between 50 and 100 years. Deterioration can begin after 25 years due to factors like corrosion and environmental conditions. Regular inspections and maintenance are vital to extending the life of cast iron pipes.
Clay pipes typically last between 50-60 years, while PVC pipes are expected to last 100 years before requiring replacement.
The Life Expectancy of Your Sewer Line
PVC piping is light, waterproof, and long-lasting. Clay pipes can last 50 to 60 years, while PVC pipes can last more than 100 years. However, sewer lines often experience issues years before they reach their life expectancy.
Lets talk a little about average or possible cost of replacing your cast iron sewer pipes. The overwhelming majority of our estimates range from 15,000 to 25,000. Sometimes but not often we see estimates ranging from 25,000 to 35,000 and although it happens it is extremely rare to see an estimate over 35,000.
Prone to Rust and Deterioration
The main drawback to cast iron piping is that it can rust over time when exposed to damp subterranean conditions. If not properly and regularly maintained, a cast iron pipe may rust to the point that it develops holes and begins to leak.
If you live in a home built before 1975, your pipes are probably made of cast iron, and you should check them for damage.
If you had no previous knowledge that your pipes could deteriorate because they are made of cast iron, then you could have a claim.

Should You Repair or Replace Cast Iron Drain Pipes? Because cast iron piping was only designed to last 50 years, it's best to replace your pipes sooner rather than later if you start to see deterioration. Many factors lead to the breakdown of cast iron pipes.
In many cases, there are only a few problematic areas that are damaged and need replacement. If this is the case, trenchless pipe relining is the best option to repair your cast iron drain pipe.
In the United States, they came to be used very early on and were still very popular until relatively recently. Clay pipes started being phased out in the 1960s and 1970s when plastic sewer pipe options such as ABS and PVC were developed.
PVC sewer pipes
PVC Pipe can last between 50 to 80 years. PVC Pipe is great when there is small ground movement as it is flexible and can move with it.
Cast iron sewer pipes have a life expectancy of 50 to 75 years and in some instances, much longer. Unlike an appliance where you may want to get the newest energy-saving version, you should not replace your sewer line if it's still in good working order. That's like flushing hard-earned money down the drain!

Acrylonitrile Butadiene Styrene (ABS)
ABS sewer pipes are similar to PVC. These black plastic pipes have become popular in recent years due to their strength and shock resistance. They are a great choice for underground sewer lines.
Orangeburg pipes, also known as bituminous fiber pipes, were widely used as sewer pipes in the United States during and after World War II, especially from the 1940s to the early 1970s. These pipes were made from layers of wood pulp impregnated with coal tar pitch.
Wondering why is sewer line replacement so expensive? It boils down to skilled labor costs, quality materials, extensive excavation, and stringent regulations.
