In my years of supplying plumbing materials, I’ve seen many clients confused about CPVC certifications. They often ask if CPVC pipes are truly safe for drinking water applications. Yes, CPVC (Chlorinated Polyvinyl Chloride) does meet NSF drinking water standards when properly certified. CPVC pipes and fittings used for potable water must comply with NSF/ANSI 61, […]

I once watched a DIY installation fail because someone skipped the preparation steps. The joint leaked within hours, causing water damage. This taught me that proper CPVC installation starts long before you open the cement can. To install CPVC with solvent cement, you need to properly prepare the pipes, apply cement correctly, allow full curing

I’ve seen metal pipes fail repeatedly in chlorinated water systems. This experience made me appreciate why CPVC has become the preferred material for such applications. Yes, CPVC is highly resistant to chlorine corrosion. Its molecular structure is chlorinated during manufacturing, making it inherently inert to chlorine and other oxidizing chemicals. This allows CPVC to maintain

I’ve seen too many hot water systems fail due to corrosion and scaling. That’s why I now recommend CPVC for all hot water applications. CPVC is the ideal choice for hot water lines because it withstands high temperatures up to 200°F (93°C), resists chlorine degradation, prevents scale buildup, and costs significantly less than metal alternatives.
