What Causes a Buildup in Cast Iron Pipes?

What Causes a Buildup in Cast Iron Pipes?

Posted in Pipe Repair, on May 13, 2023

Cast iron pipes have been commonly used in homes and buildings for their durability and longevity. However, every material has a limited lifespan, particularly cast iron. Cast iron pipes can clog and deteriorate over time, causing various plumbing issues requiring a professional plumber. The buildup of debris and corrosion is a significant concern in cast iron pipes leading to blockages and pipe failure. Our blog explores the causes behind cast iron pipe buildup and options for professional cast iron pipe repair by reliable plumbing companies like Broward Plumbing. Here’s a low-down on cast iron pipes and modern plumbing solutions to keep your plumbing flowing smoothly.

Calcium & Mineral Pipe Buildup

Over time, these deposits can restrict water flow, leading to blockages and persistent clogs. Calcium buildup is particularly prevalent in areas with hard water containing high levels of minerals. In severe cases, calcium buildup can trigger nasty backups and burst pipes that require immediate cast iron pipe repair or replacement from a trusted plumbing company. 

Debris & Grease Pipe Clogs

Along with mineral buildup, grease and debris can also accumulate to cause pipe obstructions. Over the years, drain pipes can collect waste like dirt, hair, soap scum, food particles, sediment, and grease. Grease solidifies in the pipes and mixes with other materials to form clogs. Grease, food particles, soap scum, and dirt also adhere to the pipe walls and reduce the internal diameter and water flow. 

Rust & Corrosion

Cast iron pipes are highly prone to corrosion and rust. Hydrogen sulfide gasses are created in these pipes that eventually oxidize. This oxidation with iron produces sulfuric acid, which is very corrosive. This rusts and pits the lines from within, leading to breaks and leaks. The only solution is timely pipe repair or replacement from a professional plumbing company like Broward Plumbing.

  • Unpleasant odors: Stagnant water due to partial blockages or buildup in the cast iron pipes can cause foul smells from drains and plumbing. Cracks can also cause smelly sewer gas to escape into your home.
