Mixing materials can compromise the pipe line's temperature and pressure ratings. For that reason we always recommend any pressurized pipe system be constructed using matching piping material and schedules. Get a Price Quote.

This two step process involved melting the PVC powder on a roll mill and rolling the sheet produced up to a billet. The PVC could then be processed in a discontinuously working ram extruder to make pipe. This process was adapted from that used for celluloid and was really ill-fitted for PVC. As a result, the products were often of dubious quality.
Never-the-less, these early PVC pipes were deemed suitable for drinking water supply piping and waste water piping because of their chemical resistance, lack of taste or odor and smooth interior surface. From to over residences were installed with PVC drinking water and waste pipelines in central Germany. Both the pipelines for chemicals and those for water supply and waste water came up to expectations, as did the test pipelines in the cities mentioned above, apart from damage caused by World War II.
The PVC pipes installed in central Germany are still in use today without any major problems. In retrospect, these first PVC pipes had been made before their time, before the material compounds and machines for their manufacture had been perfected.
It was not until that the systematic development of extrusion technology began. Encouraged by the results obtained from primitive pre-war PVC pipelines, several European and American companies realized the enormous potential for PVC pipes.
These companies pursued the technology, both in formulation and processing. Systematic research and trials were successful in the development of effective stabilizers, lubricants and processing aids, together with processing machinery engineered specifically for PVC. During this time period, PVC pipe began competing with traditional products in a number of major markets, such as: gas distribution; sewer and drainage; water distribution; electrical conduit; chemical processing; and drain, waste and vent piping.
Hi Heidi, thanks for checking out thePlumber! That is a great question that unfortunately has no concrete answer. As with any new technology, you have early adopters and late adopters — the widespread use of PVC took a couple of decades, for a variety of reasons. It is also worth noting that PVC like any other technology has evolved and gotten better and more specific to certain applications over the years.
Copper piping lasts for over 50 years and is the standard hard pipe within the plumbing industry. A rigid copper pipe is typically used for water supply lines, whereas flexible copper pipes are used in tight spaces where the malleable copper can bend. Although cast iron and galvanized piping are rarely installed in new construction homes, you may have these pipes if you have an older home that was built in the early 20th century.
A cast-iron pipe is strong and durable and is still used today for parts of water distribution systems. Cast iron pipes are heat-resistant and reduce the sound of moving water. Both pipes are prone to rust and corrosion over time and have been swapped for copper or plastic pipes in residential plumbing repairs. Copper pipes last roughly years, so if your house was constructed fairly recently, your copper pipes are probably in good shape.
If, however, your house is on the older side, you should talk to a plumber about the condition of your pipes, because if you wait to replace copper piping for too long, the metal can start to corrode, and enter your water. That said, they are still probably the most common option for metal piping. Brass: An allow of copper and zinc, brass piping is slightly less common than copper piping but has a slightly longer lifespan.
Generally, brass pipes can survive between years.
