Why Do We Prefer PVC Pipes Instead of Cast Iron Pipes?

Updated: Oct 26, 2020

Even though cast iron pipes are no longer used in construction, nearly 40% of all Florida homes have cast iron pipes. The problem with cast iron pipes is that they are susceptible to corrosion and leaking. The life span of these types of pipes is even less in Florida compared to other parts of the country due to the weather conditions.

When these cast iron pipes leak, they can cause extensive damage. These pipes are behind walls and under the slab foundation where you do not see them. Unfortunately, like most things in life, when they are out of sight, they are out of mind. These pipes only get thought of when it is too late, and they are already leaking. Once they have leaked, the damage has already begun.

If you find yourself in this position, you are not alone, and we can help.  

How Can You Tell If Your Cast Iron Pipes Need To Be Replaced?

There are a few dead giveaways that cast iron pipes need to be replaced. These can include:

  • Bad smells (sewer gases)

  • When a cast iron pipe system deteriorates, the pipes corrode and develop holes. When a sewage pipe has holes in it, the sewage that's in it leaks into the concrete slab. Concrete is porous and absorbs this smelly wastewater and, in essence, becomes a septic tank holding this foul smell.

  • Warped or separated wood floors

  • Tiles popping up or water stained grout

  • Water stained or discolored carpet

  • Pest infestation (rodents and roaches)

  • Slow or clogged drains

  • Bubbles in the toilet

Just because you have not seen water damage as a result of leaking from cast iron pipes does not mean that they are not leaking. Cast iron pipes are under your concrete slab and behind your walls. Leaks can start as small as a pinhole before they gradually become bigger. Pinhole leaks may go on for some time before they are noticed, usually once the leak has become larger, creating noticeable water damage. This is especially true for leaks under your concrete slab foundation. Again, just because you do not see water damage, it does not mean your cast iron pipes are not failing. There are other signs that your cast iron pipes are failing and need to be replaced. Brown residue coming from sinks can is a sign the cast iron pipes are deteriorating and failing, as it is a sign of rust. These are pipes that need to be replaced.
