Of the different types of plastic pipe used for water supply, PVC pipe has a wide variety of plumbing uses but is mostly used for drainage PVC is rarely used in potable water applications, and in many jurisdictions it is not considered safe for drinking.
Why is CPVC not used anymore?
We find the CPVC becomes brittle at the eight to ten year old mark and is more prone to failure on the hot side. It recently came to our attention that most Home Builders have switched from CPVC to Pex due to the high failure rate. Considering the CPVC is cheaper and easier to use in new construction than Pex.
What is the lifespan of CPVC?
approximately 50 to 70 yearsAccording to plumbing expert Dan Smith, PVC and CPVC are the most common choice for drain lines in newer builds and “will likely outlast any homeowner” thanks to a lifespan of approximately 50 to 70 years. Furthermore, PVC and CPVC pipes better withstand water hammer, so no “knocking” pipes during the winter.

PVC pipe is by far the most commonly used pipe in residential homes. This type of pipe is affordable and available in a number of different fittings and sizes. It's also a great choice for most warm and cold water applications.
Is PVC pipe good for drinking water?
PVC pipes are a safe choice for transportation of drinking water. This is due to their high degree of inertness and resistance to corrosion. PVC pipes are therefore free from bio-film contamination that can be a breeding ground for bacteria. By helping provide clean water, PVC pipes are beneficial to public health.
Whats better 1 2 or 3 4 water line?
Running 3/4" piping from the 1/2" feed will slightly decrease the pressure loss, meaning you'll get more pressure at your fixtures, but the difference will probably be very small. Most of the pressure loss will have already occurred in the 1/2" line before it reaches your house.

What material is used for plumbing?
Thankfully, there are many other material choices for your home’s plumbing system pipes. Galvanized steel, copper, CPVC, and PEX are all typically used for pipes. Each material has different strengths and weaknesses, in terms of how they handle extreme temperatures, how long they last, how easy they are to install and repair, and how long the pipes will last.
What is PEX pipe?
PEX pipes: Pipes made from PEX (cross-linked polyethylene) are more durable than copper and can handle both hot and cold water temperatures. PEX is much more resistant to acidic water than copper. These pipes, also called XLPEI pipes, are an affordable option and often last for more than 50 years.
What is the best pipe for high temperatures?
CPVC pipes: For a plastic pipe that can withstand high temperatures, CPVC is a great option. CPVC, which stands for chlorinated polyvinyl chloride, is more flexible and can handle much higher temperatures than PVC. CPVC pipes can handle water heated up to 82 degrees Celsius, so warping isn’t an issue.
How long do copper pipes last?
However, with age and use, copper pipes begin to thin and leak, though they should last for up to 50 years.
How hot can PEX be?
PEX can handle water heated up to 120 degrees Celsius without melting or warping. It’s easy to use and install, as it’s flexible and doesn’t need many joints, and it’s easy to transport.
Is PVC pipe bad for you?
It’s made of vinyl chloride and organotin compounds which can cause negative health reactions and are carcinogenic. Chemicals usually stay locked inside the pipe material but can leach into your water supply. In fact, drinking water from a PVC pipe may have a plastic taste to it. This is why we discourage PVC plastic pipes from being used for drinking water.
When was vinyl chloride found in water pipes?
An analysis by the American Society of Civil Engineers (ASCE) found concentrations of vinyl chloride that exceeded the maximum safe level in PVC (polyvinyl chloride) pipe manufactured before 1977, but primarily in water utility dead-end pipes where the concentration could build over time.
When was the composition of the water line changed?
A protocol was designed for water utility managers to flush dead-end lines to reduce the the contamination and, secondarily, the composition was changed after 1977 to solve the vinyl chloride leaching problem.
What is CPVC pipe?
CPVC is the proven house piping material of choice to transport potable water for over 60 years. It is also certified by all the above mentioned bodies. Most of the developed countries have long ago adopted this material and created standards to encourage adoption of this material in their countries.

What is the standard piping material for plumbing?
From Copper Pipes to Plastic. Since the 1970s, the standard piping material for home plumbing has been copper. Copper replaced galvanized steel, which tended to corrode and place lead into the water supply.
What kind of pipe is used in a house built in 1970?
As we mentioned above, a home built pre-1970 may have galvanized steel —or even iron and lead—pipes in it, and not only can these put harmful chemicals into the water, they are prone to corrosion and decay. Your home may also have an older type of plastic pipe, polybutylene, which isn’t harmful for water quality but which breaks easily.
Is copper piping safer than plastic?
Copper is safer since its corrosion-resistant, although older copper installations (before 1990) might have lead-based soldering on them. Plastic piping started to become common around the same time as copper, principally PVC, CPVC, and PEX.

Additionally, despite being capable of handling hot water, it cannot be directly connected to a water heater. For a hot water flow to work, you need a hot water safe option ...
Does PEX pipe need glue?
One of the main positive aspects is that PEX does not need glue to be held up. Also, unlike CPVC, cold temperatures are no problem for PEX pipe. This durable pipe can withstand both cold and hot water. While water temperatures are not a major issue, PEX pipe does require more specialized tools and fittings to work properly.
Is CPVC pipe good for drinking water?
The downfalls of PVC pipe are where CPVC excels. Known for its capacity to withstand heat as well as its ability to safe ly carry drinking water, CPVC has a variety of traits useful in residential water lines. Using this type of pipe will also help you to avoid water hammer, an annoying trait that occurs in many water piping systems where the pipes making a knocking noise when turned off quickly. Additionally, CPVC is a common replacement for copper pipe systems because it is easier to work with.
Why is plastic piping important?

Why is stainless steel used in water?
Stainless steel. Stainless steel is the most common option due to historical use and because it is not prone to corrosion or leaching when used with deionized or pure water. At elevated levels of purity, stainless steel may leach over time and can corrode in case the water’s pH ever becomes too acidic or alkaline.

Can water damage piping?
Any of those contaminates can alter chemical reactions, cause scaling and corrosion for piping systems, and create a number of unique problems for specific applications. Once demineralized and deionized, water can still harm piping systems if the wrong material is specified because pure water becomes more reactive.
