Cast iron pipes are expected to last as long as 100 years. But pipes in millions of homes in Southern Florida have failed in as little as 25 years because of weather and environmental conditions. Repairing failed pipes can cost tens of thousands of dollars, and some insurance companies have refused to pay for the repairs,which has caught most homeowners off guard.
Why are pipe failures in houses built in South Florida so much higher than in the rest of the country?Part of the problem is that the original cast iron pipe has no paint protection and is very rough inside, which traps fibrous materials such as toilet paper and keeps them until they become blocked.And the use of irritating chemical cleaners in daily life accelerates the corrosion of metal pipes.Another problem is the corrosive nature of water and soil in Florida. “When water and sewer gas corrode from the inside, it starts to corrode from the outside,” said Jack Ragan,a plumber. “This is a double whammy.” This means that the effluent flowing into the drain pipe will flow to the place where it should not.
The inner wall of SML cast iron drainage pipe which meets en877 standard is epoxy resin paint, and the inner wall is smooth to prevent scaling and corrosion. The outer wall coating is antirust paint, which provides good protection for the pipeline in humid environment. Therefore, en877 standard SML epoxy cast iron drain pipe will have a longer service life.
