What Are PEX Pipes? PEX is short for cross-linked polyethylene. PEX pipes, which are used for radiant heating and cooling systems, water piping, and insulation for electrical cables. PEX can be bent, twisted, or crushed, to some degree, and it will return to its original shape.
What are the advantages of using PEX pipe?
4 Benefits of Plumbing with SharkBite PEX Flexibility & Faster Installations. One of the main benefits of using PEX pipe versus rigid pipe is its flexibility. Durable & Freeze Resistant. PEX resists scale buildup, which is common in copper pipe. Confidence & Peace of Mind. Proven & Guaranteed.
Where is PEX not allowed?
PEX can’t be installed in high heat areas. You can’t install PEX in high heat areas like near recessed lighting. This also means you can’t connect PEX directly to a hot water heater, but you can use a connecting material to do this.
Is PEX pipe good for plumbing?
All this makes PEX an excellent piping material for hot and cold water systems, especially since it is flexible and well adapted for temperatures below freezing all the way up to 200 degrees Fahrenheit. PEX is easy for plumbers to install and has fewer joints, bringing your costs down.
Where can PEX pipe be used?
In general, PEX piping can be used for: Water supply lines or portable distribution systems. Radiant floor heating applications. Heat transfer applications, such as floor cooling, snow melting, and permafrost protection. Water distribution for hot water applications, including radiators. Residential fire/sprinkler systems.
Is PEX better than PVC?
When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corrode. When you compare the material costs of PEX vs PVC, PEX comes out more expensive. (However, balance this factor against the lower labor cost to install PEX.)Feb 14, 2019.
What is the disadvantage of PEX pipe?
Disadvantages of PEX Piping Most types of PEX piping are not designed to be exposed to ultraviolet (UV) light for a prolonged period of time. Light from the sun and the light bulbs in your house may cause damage to this type of plastic water line.
Is PEX OK for drinking water?
The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX). There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.
How long will PEX piping last?
Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
Do rats chew through PEX pipe?
Mice and rats will chew through anything they can, including plastic, so PEX tubing is at just as much risk as the plastic-coated wiring in a car or an HVAC unit. While all rodent damage can be expensive, if rodents chew through a home’s PEX water pipes, the result can be disastrous.
Is PEX plumbing better than copper?
We generally belive that Plumbing PEX Tubing is much better than Copper for most, if not all, plumbing systems. PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe. PEX Tubing is cheaper because it takes much less labor to install. PEX Tubing is quickly becoming the industry standard.
What is better PEX or copper?
PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.
Should I replace copper with PEX?
While copper is an excellent material, no material is perfect. You can develop some problems with your copper pipes, and PEX is often a great replacement that can eliminate these problems. Keep hot water hot: PEX keeps the water warmer as it flows through the pipe so that you get hotter water on the other end.
What is the safest pipe for drinking water?
Copper pipes with lead-free joint materials are the best choice for water pipes. They are long-lasting and won’t leach chemicals into your drinking water.
Does PEX pipes freeze?
PEX pipe will expand if frozen and contract to its original shape when thawed. But putting frequent stress on the system weakens it, increasing chances of failure and leaks. So, to preserve the strength of your pipes, you should use the same standard insulation precautions with PEX to keep it from freezing.
Can PEX pipe be used for hot water?
Where is PEX pipe approved for plumbing use? PEX pipe is approved for residential and commercial hot and cold water distribution systems, municipal water service lines, radiant panel heating systems, hydronic baseboard heating systems, snow and ice melting systems and building services pipe.
What is wrong with PEX plumbing?
PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible to oxidative degradation.
Does PEX get brittle over time?
Defective PEX pipes will not last 50+ years as advertised and quickly degrade and become brittle when exposed to hot chlorinated water. We are experts in PEX analysis and will determine if the pipe failed due to defective installation or because of a manufacturing defect.
How long does PEX last underground?
PEX has a life expectancy of 40-50 years, made possible by its durable and non-corrosive materials. Burial also reduces sun exposure, which would otherwise degrade the piping. Additionally, PEX tubing materials allow for expansion, making them resistant to freezing/cracking underground.
Will bleach hurt PEX pipe?
Most water in the U.S. is treated with some level of chlorine in order to disinfect the water supply. It has been found that chlorine can cause oxidation on the inner wall of PEX piping, eventually resulting in failure.
