The plumbing system is one of the most significant innovations made during man’s evolution. It has effectively eliminated those dark days when wastewater would travel in the same pipes as potable ones, which often led to contamination and diseases.
More innovations were developed as plumbing works progressed, notably PEX pipes. These are sustainable plumbing materials known for their flexibility and durability.
The Predecessors of PEX Plumbing Pipes
Lead-based pipes have been used in many home plumbing systems for a long time. Their widespread use has resulted in several major health problems, including lead poisoning, which led to miscarriages and infant deaths. The switch to iron plumbing became inevitable, and this happened in the 1800s. Cast-iron piping was able to provide better pressure regulation and distribution. Indoor plumbing also became possible during this time, leading to modern plumbing as we know it today.
Over the years, cast-iron plumbing proved to be susceptible to corrosion, mainly when water contains high levels of minerals. Property owners were often forced to make costly repairs. It changed in the 1950s when plastic plumbing materials were introduced to the market.
The Rise of PVC and PEX
Following World War II, there was a shortage of steel pipes, leading to the introduction of PVCs, also known as polyvinyl chloride. These consequently quickly replaced galvanized iron pipes as preferred plumbing materials in many commercial and residential areas.
Further experimentations with PVC pipes led to the development of PEX, which originated in Europe. The material was initially used to heat chicken farms, then flooring, eventually gaining popularity due to its versatility and ease of use.
Features of PEX Pipes
Switching to a complete polyethylene plumbing system can significantly affect how your plumbing works. Consider the following PEX features:
1. Color-Coded
The advantage of PEX plumbing pipes is their availability in three colors: white, red, and blue. These colors are used to indicate the water temperature that the pipe can carry. Briefly, the red pipes are for hot water, and the blue pipes are for cold. White pipes, meanwhile, can be used to heat or cool water.
2. Flexible
A PEX plumbing pipe has more flexibility than the traditional type. It eliminates the need to install smaller pipes to each fixture’s primary water source. One PEX pipe can connect to the main source and still allow water to pass through floors and walls until it reaches the target fixture.
3. No Soldering
With copper, galvanized steel, and cast-iron pipes, said one Denver plumber, soldering is needed so water can be transported to every fixture in the home. This is hardly the case with PEX pipes as they are flexible and can be fitted easily by simply making minor adjustments to your main pipe. The “fittings” required to attach every cross-linked polyethylene pipe to the water supply are also minimal.
4. Temperature Resistant
Cross-linked ethylene pipes can withstand extreme temperatures. However, plumbing professionals want to clarify that they are not freeze-proof. These pipes can still expand at low temperatures because of their chemical composition. Nevertheless, PEX pipes will not be easily damaged by the harshness of winter, ensuring that leaks and property flooding can be avoided.
5. Silent Water Transport
Galvanized steel and copper pipes can make a loud banging sound when transporting water. The noise is what plumbers refer to as “water hammer.” It happens when the shutoff valve in a high-pressure system suddenly closes. Water hammer is unpleasant and can damage your plumbing system if not addressed. Cross-linked polyethylene pipes reduce water hammer incidences because they are flexible and pressure-resistant.
Benefits of Switching to PEX Pipes
PEX pipes offer many advantages over traditional piping systems. These include the following:
1. Sustainability
Because polyethylene pipes are more cost-effective and durable than copper, cast iron, or galvanized steel, they have become quite popular among plumbers and homeowners.
A 2016 Journal of Cleaner Production study and an updated follow-up by the European Plastic Pipe and Fittings Association found that PEX pipes can be installed 30 percent faster than other plumbing materials. They can also resist corrosion and leakage by up to 75%.
2. Winter Damage Prevention
Water often freezes during winter, and its particles cause intense pressure, which can lead to cracks in your pipes. Cracks can cause leaks once the frozen water begins to melt. Because PEX pipes can expand at low temperatures and withstand high pressure, serious winter damage is effectively prevented.
3. DIY Opportunities
PEX piping is flexible, encouraging amateur plumbers to try new things, especially regarding their plumbing. Since complex processes such as brazing or soldering are not needed when installing PEX piping systems, wannabe plumbers face fewer risks if they just perform basic plumbing work.
Key Takeaway
Thus far, PEX pipes are seen as the best plumbing material that has been developed. It is not surprising, given the various features that this piping type carries. Among others, PEX pipes are durable, flexible, rust resistant, and can withstand cold temperatures. It’s no wonder that they have remained popular among veteran plumbers and newbie homeowners.
