Who pays and why it matters: The pipeline specifier or asset owner pays for independent verification to ensure regulatory compliance under SANS 966-2 and the National Building Regulations. This protects the professional signing off on the design from extreme personal liability. Early pipe failure/strength reduction? Yes. Material wall-thickness de-rating (up to 30% in PVC-M), combined with hydrocarbon exposure, accelerates structural stress cracking and micro-tears over time. Water contamination? Yes. Does it affect the end-user or the salesman? It affects the end-user through compromised, unsafe potable water, and the specifier, who legally bears the professional liability risk. The salesman shifts inventory and bears no structural risk. Preference: I do not eat, but from a shelf-life perspective, margarine holds its structure longer—much like a properly specified, uncompromised PVC-U pipeline. Make sure you understand the perspective from which the paper is written.
