At the time of the first sewer systems, cast iron was one of the best materials for pipes. It is durable and can withstand high water pressure. In addition, it is lasting (up to 100 years) and has good soundproofing properties, drowning out the sound of running water.
Cast iron pipes were first used began to be used for the first time in the 17th century in Europe. They were used in the palace of the French king Louis XIV. In the 19th century, cast iron sewers began to appear in the United States. They quickly gained popularity, as they surpassed other materials in terms of reliability and gave way only after almost a century to plastic.
The advent of plastic pipes completely ousted cast iron pipes from the market. Plastic is more flexible, less expensive and just as durable. It is faster and easier to produce.
Is it worth replacing cast iron sewer pipes with plastic ones?
In some old houses, a cast iron sewer system may still be found. Is it worth it to change it to a plastic counterpart? The unequivocal answer is yes. Cast iron pipes are at risk of being damaged by tree roots. The roots are able to go to very great depths and grow through even small gaps in the joints. Also, cast iron can be damaged by impacts and gradually corrode under the influence of modern household chemicals, especially cleaning products and preventing blockages.
