The acronym CPVC stands for chlorinated polyvinyl chloride. It is often but not always a cream-colored or off-white plastic. This type of pipe can stand temperatures up to about degrees Fahrenheit or so this depends on the schedule , so it can be used for both hot and cold water lines.
Also, make sure the glue specifies that is can be used on CPVC. PEX stands for cross-linked polyethylene. It is sometimes known as XLPEl. With good resistance to both hot and cold temperatures, PEX is commonly used for both hot and cold water lines in homes, and for hydronic heating systems such as radiant under-floor systems. PEX is considered more durable than copper, with a likely lifespan of more than 50 years.
For professional plumbers, PEX tubing has now largely replaced copper and other plastics used for water supply pipes. They prefer PEX because of its low cost, and because it comes in long rolls of tubing that are easy to transport. Because the flexible tubing can be bent around corners, fewer elbows and other fittings are required, speeding up installation.
PEX can be joined in many different ways, including push-fit fittings and crimp rings secured with specialty PEX tools. Galvanized Pipes… an end of an era. International Association of Certified Home Inspectors. Plastics Pipe Institute.

If you need to curve your piping around a rock or wall, more pipe elbows will need to be used. Lastly, copper is notoriously expensive, making this option impractical for anyone on a budget.
PVC pipes are a common pipe choice for a lot of home projects. PVC is cheap and resistant to corrosion and rusting. And although PVC is sturdy, it is not flexible. This means more fittings and elbows when installing your underground water line. Additionally, some states and counties do not permit the use of PVC for underground water lines. Always check with your municipality or contractor on what you can use.
If there are no laws against it, PVC is an affordable choice. The answer is going to vary depending on what state you live in. Even at that, different counties and cities of the same state may have different requirements.
Generally speaking, water lines should always be placed below the frost line. This ensures that the water line will not freeze.
Make sure to call before you dig. They will help you identify where, if any, utility lines are currently buried on the property. This is another question where the answer may vary depending on where you live. A 1-inch pipe would be even better for you main water supply line. The larger the pipe, the higher the water volume you will have flowing to the house.
Think about a water hose. When you squeeze the hose, you can feel the water build under your thumb. The small diameter of the pipe would increase the speed of the water, but when it comes to your main water lines, you should be more concerned about volume. Your underground lines are essentially there to carry the volume. The interior pipes in your home should be smaller in diameter to help with desired water pressure.
Frozen underground water pipes are a scary thought. If your pipe freezes, the water can expand and burst the pipe. Water main pipes can be made from a variety of materials, including metal, clay, concrete, and plastics. In terms of size, the most common water main pipe diameter ranges from 6 to 16 inches, although there are 8, 10, and inch options available as well.
Here is a list of the most common water main piping materials:. An important question still remains: what kind of pipe material is best for a water main system? Each piping material has its own unique characteristics, and which one would be best for a particular water mains application depends on a variety of factors.
Water main pipes need to withstand the specific soil and water characteristics of the water supply application. Some pipe materials are too brittle, while others may be too chemically unsafe. Throughout history, the primary types of water main pipes changed from vitrified clay and concrete pipes to cast iron and ductile iron pipes in the 20th century. Although many of these pipes are still used today, especially those made from ductile iron, most new water main applications use HDPE and PVC pipes owing to their unique properties.
PVC pipes , in particular, are inexpensive, lightweight, and durable, as well as highly resistant to corrosion and most chemicals.
