What Are Cast Iron Pipes?


Cast iron pipes are a type of piping that is commonly used in plumbing systems. They have a number of benefits that make them a unique choice for many applications. In this blog post, we’ll take a closer look at what cast iron pipes are and some of the advantages and disadvantages they offer. So, if you’re curious to learn more about this versatile piping material, keep reading!

What are Cast Iron Pipes?

Cast Iron is a durable material often used to make plumbing pipes because it can withstand high water pressure. The durability of the Cast Iron pipe material ensures that the fixture will not break down during periods of excessive water flow, which might happen if there were corrosion.

Benefits of Cast Iron Pipes

Cast Iron pipe material has a number of benefits that make it attractive as a choice for plumbing systems. These include:

  • Durable
  • Long-lasting
  • Can handle higher water pressure than most other types of piping – The water pressure might often become too high in homes that use copper or PVC piping and this would cause the pipes to burst. Cast iron can endure higher water pressure than most other materials.
  • Aesthetically pleasing
  • Easy to paint.
  • Cheaper than most other materials because it is relatively easy to produce.

Drawbacks of Cast Iron Pipes

There are a few drawbacks associated with this type of pipe material, but there are some. These include:

  • Heavy
  • Cannot be used where weight is a factor or where accessibility for repairs is important
  • Corrodes easily

The main criticism against this type of pipe material is that it is heavy and therefore harder to install.

The weight of this type of pipe material cannot only make the installation process more difficult, but it may also cause problems in installations where an accessible location for future repairs is desired.

The weight of the Cast Iron piping system can be particularly problematic when trying to install plumbing fixtures such as vanities, toilets and sinks – usually fixtures that are much lighter than the piping itself.

In many cases, this type of pipe material is not used when weight is a critical factor to consider or in places where accessibility for repairs is especially important.

How are Cast Iron pipes made?

Cast Iron pipes are made by being poured into a mold and allowed to harden. The material is heated until it liquefies and then poured into the mold.

Once it has cooled, it is removed from the mold, sanded to remove any rough edges and then painted or coated with another material before installation.

How long do Cast Iron pipes last?

Cast Iron pipe material has an average lifespan of about 100 years. However, this type of piping is often replaced when it becomes corroded, which can shorten that lifespan.

Are Cast Iron pipes outdated?

Yes, in some respects these pipes are outdated because the material used to make them has been replaced by other types of piping that are easier to install.

However, many homes still have Cast Iron pipe material installed, and if this type of plumbing system is properly maintained it will continue to function for decades.

Do Cast Iron pipes freeze?

No, it is not likely for cast iron pipes to freeze because they are designed to withstand freezing temperatures.

Should you replace Cast Iron pipes?

Only if they are corroded or damaged. Otherwise, it is recommended that you leave them in place.

Do Cast Iron pipes contain lead?

No, the lead content in these pipes is very low, so they are generally safe to use.

Are Cast Iron pipes covered by insurance?

In most cases, no, this type of piping is not covered by homeowner’s insurance because it is not a part of the water supply system in your home.

How can you tell if Cast Iron pipes need to be replaced?

One indication that it may be time to replace the Cast Iron piping in your home is if there are leaks. However, this does not necessarily mean that you need to replace the entire piping system, as it might be a simple fix.

Another indication that your Cast Iron pipe material should be replaced is if there are any signs of corrosion or rusting. It may simply be time to do some preventative maintenance and repair any issues with the existing system.
