#19 Why does recirc creep occur in DHW systems? (with Cody Mack)

Greg and Dan invite "the dynamo of donut testing" to the series, the one and only Cody Mack. Recirc creep is something that plumbers no doubt experience. But, what is recirculation creep, when does it occur, what are the symptoms and - most importantly - what is the solution for your domestic hot water system? They'll discuss ASSE 1017 and thermostatic mixing valves. Can an aquastat be installed to fix the problem? Are certain facilities more at risk? What is the impact of piping practices? Can I dig deeper (show me the resources!). Don't know Cody? He serves as an education and training manager in North America for Caleffi. Cody also is behind-the-camera in the popular series "5 Things You Need to Know" video series. Feel free to watch.
