From Sanitation to Sustainability: The Driving Forces Behind Early Plumbing Regulation

Nie ma żadnych wątpliwości, że niektóre z tych dwóch kryteriów nie są zgodne z tymi, które należy uznać za właściwe, ale nie są zgodne z tymi zasadami.

This era establed the core safety principles that remain in all modern codes: approvate pipe sizing for pressure and flow, backflow prevention devices, and stringent material standards to prevent leaching of harmofulful substances.

Thee Energy Policy Act of 1992: A Watershed Moment for Water Efficiency
