HDPE Pipes
They are high-density polyethylene made of thermoplastic material, a product of monomer ethylene. They are among the pipes you should think about for your underground water line needs. The pipes contain non-toxic materials, which do not contaminate water, and hence ideal when piping for drinking water.
PEX Pipes
PEX is an abbreviation for Cross-linked polyethylene. The pipes consist of polymers linked together by a sequence of short bonds. They are manufactured by melting high-density polyethylene polymers giving them relatively much flexibility compared to the others. They are also highly used for underground water lines.
Copper Pipes
Copper pipes are also considered reliable pipes for your underground water line. They are known for their high resistance to leaks, bursting, and corrosion.
PVC Pipes
Polyvinyl chloride, commonly known as PVC, is one of the pipes most people prefer to use for underground water lines. It is a thermoplastic material that ranks among the top three highest manufactured polymerized materials. It is preferred due to its strength, ability to withstand corrosion and rust and a pocket-friendly budget.
CPVC Pipes
Chlorinated polyvinyl chloride, commonly abbreviated as CPVC, is subjected to chlorination to enhance performance. Therefore the difference between PVC and CPVC is that the latter is a higher performer.
Cast Iron Pipes
Throughout this discussion, we have established that durability is one of the major factors to consider for your underground water line. If this is not taken care of, you will likely incur future expenses when installing pipes afresh or repairing. This aspect may make you to consider cast iron pipe when selecting an underground water line.
Galvanized Iron Pipe
Galvanized Iron pipe, commonly known as G.I, is also one of the best water pipes for your underground water line. The pipe is manufactured from mild steel, which is carbon steel with low levels of carbon. This means if the quantity of carbon was increased you would end up with cast which is used for making cast iron pipe.
Can You Bury PEX Pipe in the Ground?
PEX tubing has many uses. It is mainly used for residential water lines but also as transport for heating and cooling components, chemicals, and even sewage. PEX can be used in most instances where you’d use pipes made of copper, CPVC, or PVC.
What Type of PEX Is Best for Underground Use?
PEX – cross-linked polyethylene (sometimes called XLPE) – comprises ethylene molecule chains, or polymers. These non-connecting polymers create the flexibility of PEX in two density types – high (HDPE) or low (LDPE). HDPE has tighter packed polymers, giving it more impact resistance than LDPE.
How Deep to Bury PEX Water Line?
PEX pipes and all underground piping should be buried at least 12” to 18” below the frost line to protect the pipes from freezing. The frost line refers to the furthest depth underground groundwater begins to freeze, also called the frost depth. In colder zones, the frost line can be three to four feet down.
Can PEX Be Used Outside?
Although PEX pipe is excellent for underground use, it’s not rated for outdoor use unless properly protected. For example, PEX piping should not run along the ground without wrapping it or burying it. PEX piping used outdoors must have an insulation wrap to protect the tube from freezing.
Do PEX Pipes Burst or Freeze?
The flexibility of PEX tubing means that the pipes experience expansion if water freezes in the lines. Once the water thaws, the tube will contract back to its original shape. This ability makes PEX pipe freeze-damage resistant. However, that’s not the same thing as freeze-proof.
Is PEX or PVC Better for Underground?
PEX and PVC are both types of plastic. PVC though, is a hard rigid pipe (think of the plumbing under your sink) with no flexibility, while PEX is extremely flexible (except for PEX-C). PVC (and CPVC) was around years before PEX, making it a more common choice. Many experts will still recommend PVC over PEX.
Can PEX Be Buried in Concrete?
PEX is an HDPE (high-density polyethylene) material which makes it strong enough to handle going inside concrete. This tolerance and PEX tubing’s flexibility make it common for radiant heating embedded in concrete floors.
What Is A PEX Pipe?
Cross-linked polyethylene (PEX) pipes are flexible tubes that can be used for long runs throughout the house.
Types of PEX Pipes
Other than the color-coded property, PEX pipes have three different types.
Benefits of Using PEX Pipes
Many people do not know that PEX pipes have been around since the 1960s.
Are PEX Pipes Suitable for Outdoor Use?
Many theories circulate around the use of outdoor PEX tubing, so it can be hard to figure out whether to use it for your house plumbing or not.
What Causes PEX to Degrade Under UV Radiation?
Outdoor PEX pipes can degrade under UV light because they absorb the chlorine-blocking antioxidants that protect the pipe.
Best Method to Use Outdoor PEX Tubing
While there are many ways to protect PEX pipes from outside environment damage, a viable option would be to use the direct burial method.
Final Thoughts
Among the three types of PEX tubing, PEX-A and PEX-B serve wonderfully as the outdoor PEX tubing choice for many homeowners.
What type of PEX pipe is used for hot water?
Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).
What is PEX pipe?
Cross-linked polyethylene (PEX), a type of flexible plastic, is currently replacing traditional copper and galvanized steel as water supply lines in both new construction and remodeling projects. You’ve probably seen rolls of blue and red PEX pipe in the plumbing aisle of your local home improvement store, but might not know that this colorful tubing now makes it possible for enthusiastic DIYers to replace their own leaky water lines instead of calling a pro. Read on to learn more about PEX—what it is, where it can be used, and all the pros and cons of this popular plumbing material.
What type of fittings are used for PEX?
Hundreds of types of fittings, usually brass, are available for connecting PEX to existing copper or steel pipes, and for making connections to fixtures. Fittings are also available for connecting pipes of different sizes. The following five methods are used for making the connections watertight. Photo: amazon.com.
What is PEX tubing?
Choose the tubing best suited to your needs: PEX-A is manufactured using peroxide. This type of PEX is the most flexible of the three types and is suitable for use in all home water-supply plumbing needs.
What color is PEX?
Water flows silently through PEX, eliminating the “water hammer” noise associated with metal piping. Color-coding (red and blue) make it simple to distinguish hot and cold supply lines. PEX can be connected to existing metal supply lines with the correct fittings.
What is the advantage of PEX pipe?
PEX has a distinct advantage over these materials because of its flexibility, which allows one end of PEX pipe to connect to a PEX manifold (the main water control system) and then wind through walls and floors—uninterrupted—all the way to an individual fixture.
How long is a PEX pipe?
PEX is available in a variety of lengths, from short 10-foot pieces (for small repairs) to rolls over 500 feet long, which are used to install a home’s entire water supply system. PEX pipe ranges from 3/8- to 1-inch in diameter and its color-coding makes it a snap to identify what a specific pipe is used for. Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold.
