Have you ever received a call from a large multi-family complex with residents complaining about instantaneous domestic hot water (DHW) availability? Worse yet, have you been called out to investigate and repair pinhole leaks in a building's DHW circulation return system? New to the series, Mark Eatherton is eager to share how he resolved a 40-year-old recirculation problem that threatened to shut down a multi-family subsidized housing project due to a lack of readily available DHW in the building at the next Coffee with Caleffi™ webinar on Thursday, Aug. 22 at 12 noon CDT.

Eatherton boasts a 40+ year career in the industry, is a licensed master plumber and licensed master mechanical contractor. He loves to teach, write and educate and has been doing so for over 25 years. An avid supporter of the Radiant Professionals Alliance, he is employed by Advanced Hydronics, Inc. (Denver, Colo.) where he is responsible for designing, managing, training and troubleshooting tough plumbing and hydronic related problems.

The one-hour educational webinars are free and are intended for contractors, designers and wholesalers. A Certificate of Attendance is emailed to attendees following the event for continuing education audits. Please visit our website at for schedule details and registration.
