On "Anti-Bacterial PVC Now Available for Commercial Use"

This is a solution looking for a problem that doesn't actually exist in the field. Bacteria and algae growth in commercial drain systems isn't a widespread pain point that plumbers are losing sleep over, and adding zinc to PVC doesn't address the real failure modes—grease buildup, mineral deposits, root intrusion, poor slope, and undersizing. You're paying a premium for a marketing story, not a system that performs differently where it matters. Stick with standard PVC and focus on installation practices that actually keep drains flowing.
