About:
This 32-card set covers water supply and distribution systems, including plumbing codes, backflow prevention assemblies, water pressure standards, and piping requirements. It addresses barometric loops, dielectric unions, cross-connections, and regulatory specifications. Use it for plumbing certification exam preparation or professional reference during code-compliance training.
