Rusted Ductile Iron Pipe makes Drain Clogged

What is Ductile Iron Pipe?

Ductile iron pipe is a type of Ductile Cast Iron Pipe that is widely used for the transmission and distribution of potable water pipes. Similarly, the ductile iron used to make the water pipe is distinguished by the particles or nodular nature of the graphite contained within the iron. Also, If the house where you are living was built between the 50s-90s and still has its original sewer system, a part of that system is probably iron pipe.
Also, older pipes installed were usually made of metals like lead, copper, and cast iron that experience varying degrees of corrosion.

However, unless your home is at least 60 or 70 years old, it’s likely your cast-iron sewer pipe is in functional condition. Besides, eventually, cast iron pipes exposed to wastewater will become rusty and weak. Moreover, the rust can sometimes build up inside the pipe, blocking water from passing and causing many  problems for homes.  Similarly, there are various methods to repair severely rusted cast iron pipes and make them work like new again.

How cast iron corrodes?

When two pipes of different metals are used, over a certain time an electrochemical reaction in between them appears and leads to corrode, blocked, clogged, and damaged.

  1. Most of the houses constructed between the 50-90s have this sort of issue. People used to directly connect two separate pipes of different materials like clay and cast iron by cement and mortar, Ld(zinc). If your home has metal plumbing pipes, including copper, galvanized steel, cast iron, and brass, you will experience corrosion at some point during the lifespan of the pipe. The length of time of underground waste pipes before you experience corrosion depends on many different factors. One reason is the type of materials, the acidity of your water, and the chemical in your portable water. Experts recommend checking the ingredients on household drain cleaners, as many brands contain sulfuric acid, which accelerates pipe corrosion.
  2. Another reason is external corrosion caused by materials found in soil. Soil generally contains high levels of acidity, stray electric currents, and toxins, all of which can cause cast iron pipes to rust. External rust is sometimes not exactly a cause for concern, though it may indicate more serious problems in the internal piping.
  3. The next reason is the mature trees around your house or neighborhood. These root systems may have spread into the plumbing lines beneath our houses. If you find old trees and plants located close to your house, do some quick research on their root
