Kevin Freidt is back for the May edition of Coffee with Caleffi. In this one hour webinar, frequently asked questions will be discussed with examples from the technical support team. Kevin will describe how to identify symptoms of DHW recirculation systems that have drifted from the design intent. These topics will be discussed:

• What is proper fluid velocity, and how does it affect Legionella management?
• Can you mix and match balancing valve styles in existing systems?
• Will upsizing the circulator fix the problem? How do you double-check the circulator sizing?
• How do you make sure your system is aligned with the design intent?
• What are the most common troubleshooting problems, and how to fix them?
