Commercial Sizing, Plumbing Design, and Applications Textbook

The core module in the WQA Commercial Education offerings, this is the starting point that helps determine equipment sizing based on building demand and treatment application. The book includes step-by-step procedures and calculations for determining available flow and pressure for the distribution system and the water service; WSFU calculations, charts and conversions to flow; recommended quotation-writing procedures; a detailed site questionnaire for obtaining the necessary information to specify a system; pressure loss tables for copper, PVC/CPVC, and galvanized steel pipe; EPA’s cross-connection manual; and safety considerations.

Cost: $150 (WQA Members) $300 (Nonmembers). Please contact education@wqa.org to order.
