The history of plumbing in the United States dates back to 1804, when Philadelphia became the first city in the world to use cast iron pipes for its water and sewer system. In 1995, the New Road Community Development Group purchased properties and land, on which the Washington house is now located. This marked a major milestone in the evolution of plumbing in America. Prior to modern plumbing systems, the English Public Health Code established in 1848 was the standard guide for indoor plumbing. These restrictions ended up introducing cast iron and plastics into the manufacturing industry, resulting in improved plumbing materials.
In the mid-1930s, legislators and medical professionals agreed that sanitary piping was necessary for public health. From the Minoan toilet in Crete to the first channel systems in Mesopotamia, they all contributed to the evolution of plumbing. The idea of sanitary plumbing systems inside buildings was an American development that soon spread across Europe. With an outlet for wastewater, indoor plumbing and working toilets were getting closer and closer to paying off. It was the first hotel to have indoor plumbing and became the prototype of a modern, first-class American hotel. With eleven aqueducts serving the city of Rome, it became the first with truly extensive plumbing efforts.
By the 1950s, the company was pushing forward lines of stainless steel sinks and faucets that would become the mainstays of the plumbing industry. It wasn't until the 1930s that indoor plumbing, running water, and modern bathrooms would reach rural areas of the United States. Unfortunately, poor plumbing and the stench of open sewer connections made some new homes uninhabitable. Fittingly, the National Association of PHCC (formerly the National Association of Master Plumbers), first met in committee in 1883 at the former Astor House, the hotel that powered modern plumbing in 1834. Today, nearly every home in the United States has interior plumbing. But this was not always the case, since inland water supply was a reserve for kings and queens, and for the rich in society.
Throughout history, plumbing has required certified and qualified plumbers to perform their best effort in all buildings, especially where systems are complicated and extensive, and where large numbers of people can be affected by water pollution.
