Overview

Cast iron’s longevity, durability, and sustainability help make it the logical material choice for drain, waste, and vent piping. For 75 years CISPI has been the go-to resource for all things concerning DWV systems. As an independent authority, we don’t just advocate for cast iron because it’s in our name—we provide expert guidance based on decades of research, testing and real-world application. CISPI helps facility managers navigate complex building codes, evaluate true material costs and make decisions rooted in facts rather than marketing claims. And yes, CISPI will even tell you when PVC is the right choice for your situation. Our team is strategically located across the country and is ready to help as we strive to improve life safety, resilience, and performance of plumbing in building construction.
