Episode Synopsis
Send us a textIn this episode of Mastering Wisconsin Plumbing, host Ryan Boggs, Master Plumber and prefab foreman, shares how his team’s innovation in kitting DWV systems has drastically improved efficiency on the company’s largest plumbing project to date. By collaborating across trades, they’ve shortened shower rough-in times and improved workflow — all while emphasizing the importance of continual learning and adaptation in the plumbing trade.Ryan then breaks down Wisconsin Plumbing Code SPS 384, the section governing plumbing materials and products, explaining why understanding product listings, labeling, and material limitations is critical for compliance, performance, and professional integrity.From PVC vs. CPVC to lead-free brass and approved transition fittings, Ryan unpacks some of the oddities and gray areas that trip up even experienced installers — and reminds listeners that knowing what’s approved and installed per its listing is the hallmark of a true craftsman.To close, Ryan teases next week’s episode featuring Aaron Kilburg from NIBCO, who will share insights from the manufacturer’s perspective on product design, testing, and maintaining compliance with evolving plumbing codes.Whether you’re an apprentice, journeyman, or master plumber, this episode will sharpen your understanding of the materials that keep Wisconsin’s plumbing systems running safely and efficiently.Key Topics:Prefabrication efficiency through DWV kitting and trade collaborationThe importance of continual learning as a licensed professionalWisconsin Plumbing Code SPS 384 – Plumbing Products and MaterialsMaterial listings, third-party certification, and labeling requirementsCommon compliance issues: PVC vs. CPVC, solvent cements, transition fittingsThe installer’s responsibility for code-compliant material selectionTeaser: Interview with Aaron Kilburg (NIBCO) – coming next episodeReferences & Resources:Wisconsin Administrative Code, Chapter SPS 384 – Plumbing Products and Materials.
