What Are Cast Iron Sewer Pipes?

So what is the life expectancy for a cast iron sewer system? In our experience, at most, cast iron sewer pipes can last about 50 years. However, we’ve seen a 50-year-old system that was fine and a 20-year-old system that was falling apart.

Cast iron is a metal alloy made of iron, carbon, and silicone. Because it’s not malleable, it is cast (hence the name) in a mold to create things like pipes and cookware.

Cast iron is incredibly strong and can be long-lasting. But cast iron sewer pipes are a different case altogether. It’s impossible to care for pipes that are buried underground and have waste and water running through them. And everyone’s experienced a slow drain from time to time so if any chemical drain cleaners are used, those contribute greatly to the corroding of your pipes.

The combination of water and pipes almost always results in rust and rust buildup. After decades of use, it’s natural for the materials that run through these pipes to stick to and build up along the inside walls of the pipes. With this buildup then comes slow drains, clogs, and stoppages.

Cast iron pipes were used because they were relatively cheap and easy to install. It’s estimated that there are over 2,000,000 homes in Florida that still have cast iron pipes – as a result these plumbing systems are ultimately destined to fail.

Florida homes are susceptible to cast iron pipe corrosion and leaks because of the salt and moisture rich environment.  Residents are finding that their insurance companies are not covering costs related to water damage or leaking sewage.

A sewer backup into the home can be particularly detrimental to your property as well as to your health because you could potentially be exposed to harsh chemical additives, bacteria, and pathogens

8 Signs Of Cast Iron Sewer Pipe Leaks

Sewer Gas Odor

If you can smell sewer gas in or around your home or building, this is a tell-tale symptom that there is a crack somewhere in your sewer system.


A cracked or leaky sewer pipe behind a wall can cause the humidity levels to rise, as a result a mold problem will begin. 


Rats live in sewers and can make their way from your city/main line tie-in to the pipes running behind your walls.

Septic Waste In Yard

An obvious sign that you may have a leaky sewer pipe would be septic waste water pooling in your yard.

Foundation Cracks

More extreme symptoms of sewer pipe corrosion include foundation issues such as cracks in your foundation slab, foundation settlement, and in some cases sinkholes.

Insect Infestation

An insect infestation may also be a symptom of a broken sewer line. Insects such as cockroaches, palmetto bugs, and sewer flies have a much easier time getting through sanitary sewer cracks into your home than rats.

Slow Drainage

A slow drain may be a symptom that a blockage is forming which will eventually lead to a sewage backup and water damage to your home. 

Note: Beware of using chemical drain cleaners to solve a slow drain or blockage. As the chemical sit in the pipe they will eat away at the cast iron and/or PVC causing corrosion.

Lush Lawn Patches

Since sewage acts as a fertilizer for vegetation, leakage from your main line into the surrounding soil will give the surrounding grass extra nutrients that will result in a lush and extra green appearance.

One of the most common misconceptions regarding pipe repair is that it can be put off. While many believe that pipe failure only affects a drainage system, few understand that it can actually affect the foundation of a structure. If this is the case, the problem quickly moves from minor issue to major crisis.

Home Value

Home market values can be reduced by 20% or more due to cast iron plumbing systems that fail inspection.

No Clog No Problem

Water that makes its way down a drain does not necessarily mean there is no clog to be dealt with. There are a couple of other suggestions that a clog may be in a drain, including: A drain is producing a bad odor, Water is slow to drain, Bathtub or basement drains are backed up.
