Our #sustainability scorecard examined how pipes interact with #drinkingwater. Cast iron, steel, & copper pipes mainly release well-studied byproducts. PVC, CPVC, PEX & other #plasticpipes leach VOCs, plasticizers, organotins, antioxidants, & endocrine-disrupting chemicals. buff.ly/SU1LQph

Beyond Plastics reports that #PVC & #CPVC #plasticpipes release dozens of chemicals into water, substances that are NOT benign. They have health impacts “ranging from liver & kidney effects to adverse…outcomes on the reproductive, developmental, immune & nervous systems.” buff.ly/pATGf8V

Stagnating water in pipes lets biology & chemistry take over: Microbes & pathogens grow. Chemicals & microplastics leach from #plasticpipes. And corrosion increases from metal, most notably, toxic lead from legacy #plumbing. Done properly, flushing alleviates most issues. buff.ly/peIH7yj

When biofilms & deposits build inside #plasticpipes, the plastic, chemical disinfectants, & organic matter interact. Effects vary by material but include leaching & microplastic release. Pipe selection must address chemical as well as mechanical performance.

NSF/ANSI 61 is often touted as a gold standard for water quality. It’s not. The standard only measures a limited set of contaminants in lab conditions. That’s important, but it doesn't mean all plasticizers, catalysts, & additives commonly used in #plasticpipes are safe.

Buried pipes face loads from soil, settlement, & traffic. Unless installed with care, #plasticpipes can deform under load & float in high groundwater, causing failures. Materials like iron, copper, steel, & concrete better resist both deformation & buoyancy issues.

Why Pipe Material Decisions Now Carry Risk – Safe Piping Matters growing body of claims data, forensic investigations, and case law shows that When plumbing systems fail, the consequences extend far beyond repair costs. Architects, engineers, manufacturers,…

Insurance carriers now investigate #plumbing failures & losses in detail & #plasticpipes can raise complex issues on chemistry, temperature, & installation. Courts are also expanding design liability, raising legal/business risk tied to pipe material choices.

Are #plasticpipes bad for water? By several measures, the answer is YES. buff.ly/CK6yl3Z

Inspectors find errors with firestop installations that compromise safety, including modified assemblies, wrong sizing, & chemical incompatibilities. #Plasticpipes face more risk since they can melt & burn in structure fires

Viscoelastic Weaknesses of Plastic Pipes – Safe Piping Matters Engineering studies and forensic reviews show plastic pipe materials have mechanical behaviors very different from metals. These behaviors introduce long-term performance concerns that designers and…

Research highlights a key vulnerability of #plasticpipes: viscoelasticity, which reacts to common stresses from installation errors, settling of supports or soil, & temperature variations. Most failures occur at joints.

PLASTIC PIPES = PLASTIC PROBLEMS. PVC, PEX, CPVC, & other #plasticpipes sag without support. Are more vulnerable to chemical damage. And only seem affordable until they fail. What should you know about value-engineered plumbing systems? buff.ly/z5qUGEO

Report: Sprinkler System Piping – Safe Piping Matters This research-based report gives an overview of system components, design considerations, and material options for fire-sprinkler systems.

Sprinkler pipes should outlast the buildings they serve. But #plasticpipes are vulnerable to chemical damage, thermal expansion & failure under load. In crowded plenum spaces, the margin for error shrinks. Design for durability. Specify accordingly.

Research Shows Risks of Plastic Pipes in Fires – Safe Piping Matters Recent fire testing from the Copper Sustainability Partnership (CuSP) reinforces our findings that combustible plastic plumbing materials pose significant risks in fire conditions.

Combustible #plasticpipes may meet code but they can fail under fire. PEX burns at 430°F. PE at 630°F. PVC at 750°F. CPVC at 900°F. Structure fires can easily exceed 1,100°F. Do the math. buff.ly/vCgl2UG

Over time, flexible #PVC #plasticpipes can sag under their own weight or soil settlement, making low points that create “ponds” & trap wastewater. Unlike rigid materials such as cast iron or concrete, flexible PVC doesn’t hold its shape, reducing flow & inviting maintenance issues.

Meet DINP: a #phthalate that leaches into soil & water, especially when pipes are exposed to heat or stress. Linked to reproductive harm & hormone disruption, DINP has no business near any water system, even those used only for irrigation. Why do some #plasticpipes still use it? buff.ly/A29jBGl

Microplastics found in 81% of global #drinkingwater samples. Degrading #plasticpipes contaminate water systems even after treatment. This comprehensive study underscores the need for better material choices & standardized testing protocols to protect public health. buff.ly/qRTXBHE

PLASTIC PIPES = PLASTIC PROBLEMS. After use, #plasticpipes don’t get recycled. They degrade into #microplastics. Research finds #PVC pipe can shed 114,000 #microplastic particles/liter into stagnant water. Does it seem like plastic is a pollution pipeline? buff.ly/b0UIGiU

EPA Targets Toxic Chemical in PVC Pipes – Safe Piping Matters

EPA scrutinizing toxic diisononyl phthalate (DINP) in #PVC #plasticpipes. DINP isn't allowed in potable water pipes but shows up in DWV & irrigation systems. Why would the industry make pipes that contaminate water - even if it's not for drinking?

Plumbing will be an 'ongoing problem' at new billion-dollar airport terminal, official says An email exchange from 2016 shows that the contractor asked to cut back on plumbing hangers to keep costs down.

Weaker structure means #plasticpipes require 2–3x more hangers than metal. As NOLA airport learned, insufficient support can cause sagging, breaks, & costly repairs. IMG WWL Louisiana
