Also, using copper for critical components of your plumbing system can add value to your property.
Copper Pipes are Not Environmentally-Friendly
This all-too-common myth contends that copper isn't an environmentally-friendly option due to mining and processing practices. But in reality, copper pipework is highly recyclable. Not only can discarded copper pipe be remelted and reused, but the metal retains virtually 100% of its original performance capabilities, even after multiple rounds of recycling.
Copper Piping Causes Water to Taste Metallic
Another widespread myth about copper piping is that it causes tap water to have a metallic taste. In truth, if maintained properly, copper pipes do not alter the taste, smell, or color of your water. When water has an off-tasting flavor, other factors such as poor water quality, older pipes, or the onset of pipe corrosion are typically to blame.
Using Copper Pipe Guarantees No Pipe Bursting
While copper piping is known for its durability, it is not immune to breaks or cracks under extreme conditions. For example, in freezing temperatures, the water inside the pipe can freeze and expand, causing even copper pipes to burst. While copper pipes resist corrosion far better than iron or galvanized pipes, they are not impervious to all plumbing issues.
Copper Comes Only in Rigid, Non-flexible Forms
Copper piping indeed comes in rigid forms, but it also comes in flexible forms, known as soft copper, used primarily for refrigerant lines in HVAC systems and other applications requiring the pipe’s flexibility. This contradicts the misconception that all copper piping is rigid and unbendable.
Only Professionals Can Install Copper Pipework
While professional installation is often recommended to ensure best outcomes, technically-minded homeowners can also successfully install copper pipework themselves, espeсially if equipped with the right information. However, keep in mind that proper soldering techniques and safety precautions are essential to avoid any mishaps.

Copper Pipes are a Thing of The Past
Even amid new plumbing materials, copper has maintained its place as a reliable option for both domestic and commercial plumbing systems. The outstanding durability, recyclability, and overall performance of copper pipework make it a valuable material choice, now and in the future.
All Copper Pipes are the Same
Different types and grades of copper pipes are available, each specifically designed for different applications. For instance, Type M has thin walls and is mostly used in residential projects, while Type K has thicker walls and is used in commercial, high pressure, and underground service applications.
Copper Interferes with the Internet
This myth contends that copper pipes can affect Wi-Fi signals. However, there's no evidence to suggest that copper pipework within a building interferes with the internet or Wi-Fi signal. If a Wi-Fi signal is weak, it's likely due to the distance from the router or walls impeding the signal, not the presence of copper pipework.
It's critical to distinguish facts from fiction when it comes to copper pipework. Armed with this knowledge, home and business owners can make informed choices about their plumbing systems, ensuring durability and functionality for years to come.
Summary
Overall, copper pipework has proven its worth in various fields including plumbing, heating, and refrigeration.
