1. **Which pipe has the longest lifespan?**
Copper pipes often have the longest lifespan, potentially lasting **50–100+ years** in ideal conditions (e.g., protected from acidic water or physical damage). Stainless steel pipes can also exceed 100 years in corrosive environments.
2. **What is the most durable pipe?**
**Stainless steel** is considered the most durable due to its exceptional resistance to corrosion, heat, and physical stress. However, copper is also highly durable and widely used in residential plumbing.
3. **Which pipe is more durable?**
Copper is generally more durable than plastic pipes (e.g., PVC or PEX) due to its strength and heat resistance. However, stainless steel outperforms copper in harsh or corrosive environments.
4. **Does PVC last longer than copper?**
No. PVC typically lasts **50–70 years**, while copper can last **70–100+ years** under normal conditions. However, PVC may outperform copper in acidic water environments, where copper can corrode.
5. **Can copper pipes last 100 years?**
Yes. With proper installation and non-corrosive water conditions, copper pipes can last **100+ years**, especially in supply lines. Drainage lines may wear faster due to waste acidity.
