Cast iron fell out of favor in the 1960s and 1970s, as teflon-coated aluminum non-stick cookware was introduced and quickly became the item of choice in many kitchens. The decline in daily use of cast-iron cookware contributed to the closure of nearly all the iron cookware manufacturers in the United States.
Polybutylene was an immensely popular, cost-effective piping material for years between 1975 and 1996. It's estimated that around 10 million homes in the United States were outfitted with polybutylene pipes during their heyday.
In fact, cast iron is still a viable plumbing option, and many old homes have cast iron pipes with no issues. Instead of assuming cast iron is a bad choice for a Floydada, Texas, home, you might be surprised to find it has its advantages in the modern world.
Cast iron pipe is pipe made predominantly from gray cast iron. It was historically used as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 17th, 18th, 19th and 20th centuries.
In 1980, cast iron pipes were no longer the pipe of choice. Builders and plumbers replaced cast iron with rigid PVC (Polyvinyl Chloride plastic), which is easier to make, can be made quickly, is harder than other options, and has greater tensile strength. It is essentially a cheaper, faster alternative to cast iron.
Because cast iron piping was only designed to last 50 years, it's best to replace your pipes sooner rather than later if you start to see deterioration. Many factors lead to the breakdown of cast iron pipes.
Deciding to buy a home with cast iron plumbing is a personal choice. These pipes shouldn't automatically be a deal-breaker, but due diligence is necessary. During the inspection period, have a licensed plumber inspect the pipes to assess their condition.
Orangeburg or Bermico piping was a fiber style pipe made from layer of wood fiber and pitch pressed together and was used up until the 1970's when PVC (poly vinyl chloride) piping came on the scene. Here in sunny South Florida cast iron pipe was the norm again until PVC became the new king in 1972.
Cast iron pipes, despite their durability, aren't invincible. Most last anywhere from 50 to 100 years, but issues can crop up much earlier. Homeowners sometimes need to replace pipes before 50 years, especially if tough conditions have exposed them.
What kind of plumbing pipes were used in the 70s? Plastic. Plastic plumbing pipes in the form of ABS and PVC became widely used in residential construction in the 1970s.
It has become expensive, can still corrode based on pH levels of water, and in cold climates, frozen water can cause copper pipes to burst. PEX installs quickly, which significantly reduces labor costs.
A house built in the USA in 1950 would most likely be using galvanized steel water pipes, black steel gas pipes (called lines), and cast iron sewer pipes.
It is making a huge comeback in kitchens nationwide, and chefs are creating new recipes and cookbooks in line with the trend. The reasons for the resurgence of this old-fashioned cooking tool vary from unexpected benefits to delicious inspirations. Looking for ideas of what to make in your cast iron cookware?

Polybutylene (PB) was a plastic manufactured between 1978 and mid-1995 for use as piping in home plumbing systems. It was inexpensive and offered plenty of advantages over other materials, such as flexibility, ease of installation, resistance to freezing.
Water lines were copper and galvanized steel pretty much universally until the early 1970's. Starting in the mid 1970's, They put in a lot of PolyB which we all know the history of. Most of the underground pipe outside of the house was PVC.
Cast Iron: Cast iron pipes last between 80-100 years, and are built to withstand a high amount of water pressure. However, like galvanized steel, cast iron piping has been found to be susceptible to rust over time. PVC (Polyvinyl Chloride): Traditionally, PVC piping only lasts between 25-40 years.
Now a new study that was recently published in the American Chemical Society's journal Environmental Science & Technology has found that when corroded cast iron water pipes are exposed to residual disinfectant it can release toxic hexavalent chromium, or chromium-6, into the drinking water flowing through the pipes.
Corrosion leading to leaks
Corrosion significantly undermines the integrity of cast iron sewer pipes, leading to leaks. This degradation compromises the pipe's structure and poses a risk to the environment by allowing untreated sewage to seep into the ground.
There is some difference when it comes to assessing the life span of cast iron sewer pipes since more conservative estimates peg the range at anywhere from 50 to 65 years. More optimistic sources bump those numbers up to roughly 75 years, with some lasting a full century.
Unlike lead pipes, cast iron doesn't pose any inherent threats to your health. However, when cast iron comes to the end of its lifespan, it's susceptible to rust and other damage. When you notice the following issues, it's time to consider pipe repair or replacement: Discolored Water.
