Maintaining water pressure within an acceptable range is vitally important in all types of building plumbing systems. Unregulated systems can cause high mechanical stress on system components, flow noise, valve cavitation, water hammer and uncomfortably high flow rates from faucets and shower heads.

John Siegenthaler, P.E. will join Kevin Freidt and Max Rohr from Caleffi to explain the basics of ideal pressure reduction in modern plumbing systems. The fundamentals and design best practices in the presentation apply to residential and commercial system design. This training is best suited for attendees looking to reaffirm the underlying design and installation criteria for ideal pressure regulation in plumbing systems.

You'll learn:
→ Plumbing system pressure concepts
→ Considerations for low/high pressure scenarios
→ Calculations for dynamic pressure drop
→ When to install PRVs in parallel or in series
→ How to utilize various designs of pressure reducing valves
→ Maximum high pressure reduction ratios and recommendations
→ Troubleshooting quick tips
