What type of pipe is commonly used for potable water supply in residential plumbing?

Copper pipes are widely recognized as a reliable choice for potable water supply in residential plumbing systems. Their popularity stems from several beneficial properties. Firstly, copper is highly durable, which allows it to withstand high temperatures and pressures typically found in plumbing systems without the risk of breaking or leaking. Additionally, copper has natural antimicrobial properties, helping to keep drinking water safe and free of harmful pathogens.

Another significant advantage of copper pipes is their resistance to corrosion and deterioration, which contributes to a longer lifespan compared to some other materials. This quality is crucial for maintaining the integrity of plumbing systems over time, particularly in regions with varying water chemistries.

Though other materials like PEX and PVC are also used in plumbing, copper maintains a longstanding reputation for safety and effectiveness in carrying drinking water. PEX offers flexibility and ease of installation, while PVC is often used for drainage and sewage. However, copper remains the preferred material for potable water because of its tested reliability and performance in various conditions.
