Understanding Copper Pipes in Residential Plumbing
Copper pipes have been a staple in residential plumbing for decades due to their inherent benefits. Known for their anti-bacterial properties, copper kills any bacteria that come into contact with it, ensuring safer drinking water. In contrast, metal and PVC plastic pipes do not have this same antibacterial quality, posing a risk of contamination and potential health issues.
Despite these advantages, the use of copper pipes has been on a steady decline. The primary reason for this shift is the rising price of copper. While copper remains a durable and lasting material, the availability of cheaper alternatives like plastic has made it less competitive in the market. Plastic pipes are not only less expensive but also more durable and easy to install, requiring only gluing rather than soldering.
My Experience in Using Copper Pipes
In my recent home construction project, I opted for copper pipes for the water supply and ductile iron for the drainage system. As someone from the 'old school,' I believe in the durability and permanence of these materials. Building my home with these materials ensures long-term reliability and lower maintenance costs in the future.
Plumbing with copper has been around for much longer than the plastics commonly used today. Copper pipes are known for their strength, durability, and longevity. They are less prone to damage or failure, making them a preferred choice for many plumbers and homeowners. However, the main factors driving the use of plastic pipes today are their lower cost and ease of installation.
City Policies and Pipe Replacements
In the city where I reside, I have observed a significant shift towards plastic piping. Over the sixteen years I have lived here, the city has been gradually replacing old copper pipes with new plastic alternatives. My assumption is that this change is driven by cost-saving measures and expedient installation. Additionally, the city has been focusing on improving road drainage systems to prevent water from entering the nearby river, a project that has involved extensive pipe replacement.
My decision to use copper for the water supply in my home, apart from aesthetic and commitment to quality, stems from specific scenarios. For example, if one is setting up an open loop solar hot water system, copper pipes are preferred over PEX plastic tubing. This is because the temperatures in solar collectors can reach close to 180 degrees Fahrenheit, which is well beyond the temperature tolerance of PEX tubing. In such systems, copper is a better material due to its ability to withstand higher temperatures and its reliability in direct solar heat exposure. Closed loop systems, on the other hand, use copper tubing to efficiently transfer heat without direct exposure to solar temperatures.
Overall, while copper pipes face increasing competition, their unique benefits make them a valuable and enduring choice for many residential plumbing projects. Whether it's the antibacterial properties, durability, or adaptability in specific applications like solar hot water systems, copper pipes remain a preferred material in modern plumbing.
