✅ What Is PEX Piping?
PEX is a flexible, plastic piping material that has grown in popularity over the last two decades. It’s often used in both residential and commercial plumbing applications.
Advantages of PEX
- Cost-effective: On average, PEX costs less than copper (both in materials and labor).
- Easier to install: Its flexibility allows for fewer fittings, making it ideal for tight or complex spaces.
- Freeze-resistant: PEX can expand slightly, which reduces the risk of bursting in Du Pont’s occasional sub-freezing winters.
- Corrosion-proof: PEX doesn’t corrode like metal piping, making it ideal for areas with acidic or hard water.
Disadvantages of PEX
- UV sensitive: PEX breaks down when exposed to direct sunlight, making it unsuitable for outdoor use.
- Chemical leaching: While PEX is generally safe, some studies suggest certain types can leach small amounts of chemicals. Source: InterNACHI – Copper vs. PEX
- Shorter lifespan: PEX typically lasts 30–50 years, which is slightly less than copper.
🔧 What About Copper Pipes?
Copper has been a plumbing staple for over 70 years and is known for its strength and reliability.
Advantages of Copper
- Longevity: Copper can last 50+ years, and in ideal conditions, over a century.
- Resale value: Homes with copper piping are often seen as higher quality by buyers.
- No plastic taste: Some homeowners notice a difference in water taste between plastic and metal pipes.
- Naturally antimicrobial: Copper can reduce bacterial growth within pipes.
Disadvantages of Copper
- Expensive: Copper material costs have risen significantly. Installation is also more labor-intensive.
- Corrosion-prone: Water with high acidity or alkalinity can cause pinhole leaks over time.
- Poor freeze resistance: Copper pipes are more likely to burst in cold temperatures, especially if uninsulated.
💧 Du Pont Water Conditions Matter
One factor homeowners often overlook is local water chemistry. The City of Du Pont gets its water from groundwater wells, which may contain varying levels of hard minerals and chlorine.
- Copper is prone to corrosion in aggressive water conditions.
- PEX handles hard water and mineral build-up better and doesn’t corrode.
