FAQs: Corzan® CPVC for Education

Safety and reliability are the guiding principles of the infrastructure supporting educational facilities. Student health depends on piping that will remain free of contaminants and can deliver water reliably and without interrupting their education for maintenance. Plastic piping materials like Corzan® CPVC install quickly, eliminate corrosion and are certified for potable water use. Here are some of the most frequently asked questions about CPVC in this industry. If you have additional questions or would like more information, please contact us to be connected with one of our piping material experts. 

1. What piping materials offer long service life for educational campuses?

Educational facilities may choose from a broad range of piping options, but copper and CPVC often offer the longest service life. Corzan CPVC may offer the best total cost of ownership over its lifecycle due to its resilient performance over time, even at higher temperatures, pressures and chemical loads. Copper can corrode and form pinhole leaks when exposed to highly disinfected water, which can lead to more frequent maintenance and replacements. The costs to fully repipe an educational campus could cost hundreds of thousands of dollars, and copper-based projects are significantly costlier than CPVC, due to both material and installation costs.

2. How does CPVC prevent corrosion in older school building retrofits?

CPVC does not corrode. It is chemically inert to water-based reactions and its additional chlorine content protects it from the oxidizing effects of chlorine-based disinfectants. Corzan CPVC has been shown to maintain its inside diameter over time, unlike metals that experience flow reductions from scale and biofilm formation. In a retrofit situation, Corzan CPVC can be used alongside and easily joined with copper without risking an electrochemical corrosive reaction.

3. Which piping systems support laboratories and research water needs?

Laboratories must often handle corrosive chemicals and/or higher temperatures, making Corzan CPVC a suitable choice for corrosive waste systems, lab drains, and vents due to its chemical resistance per ASTM D543 and ISO 22088. For Chemical Drainage pattern fittings, ChemDrain is the only partner manufacturer offering this specialized configuration.

4. Does CPVC reduce operational disruptions during school renovations?

CPVC can significantly reduce disruptions during renovations because of its simpler installation process. Corzan CPVC can be tied into existing lines without shutting down the entire wing or building, as required for successful copper brazing. CPVC requires no hot work, so no safety shutdowns or permits are required. And the single-step solvent welding process can be completed faster than copper brazing.

5. What materials provide quiet plumbing performance in school facilities?

A third-party assessment of the noise produced by piping materials found that Corzan CPVC produced 31.7 dBA and copper piping produced 49.9 dBA. To human ears, this accounts for a sound four times louder in copper than the CPVC pipes.

6. How does piping material choice impact health and safety for potable water?

The impact of piping material choice on healthy and safe potable water is enormous. Corzan CPVC is NSF/ANSI 61-certified, meets strict lead-free criteria, and is certified non-leaching—unlike some copper piping systems. Corzan CPVC’s smooth, consistent surface gives it a lower biofilm and scale formation potential than metal and other plastics, supporting cleaner lines over time. A robust piping material like Corzan CPVC can withstand higher levels and temperatures of disinfecting chemicals as well.

7. Is PVC more cost‑effective than CPVC for commercial and institutional piping systems? 

While PVC has a lower initial cost than CPVC, it is NOT an acceptable alternative for many commercial and institutional piping applications, especially potable water systems. First cost should never be the sole deciding factor in material specifications. Always consider codes, performance characteristics and lifecycle costs. Corzan CPVC performs at temperatures and pressures PVC materially cannot and has certifications for potable water use that PVC lacks.
