Original Presentation Date: July 22nd, 2020

Discuss the basics of how to determine the system needs for different pool and spa configurations. We will start with a very brief description of how to determine water volume (gallons) and will utilize this information to determine pump selection, filter selection, pipe size requirements, and drain cover selection to assure the vessel is both code compliant as well as energy efficient. This course also covers some of the misunderstandings surrounding VGB drain covers and how to size and install them properly in the field.
