This video shows an inground equipment pad setup using a Hayward ProGrid DE filter. DE filters are the best filter you can buy in terms of how effecient they are. The one drawback is dealing with DE powder when you backwash and or clean the filter.
This system has a 1hp Hayward superpump, a ProGrid 4820 model DE filter, HeatPro heatpump, and Aqu-Rite salt system. You will notice the 3-way union valves we use to control water flow on the suction and return side. We like using the union valves because they can be broken down easily when you close your pool, or need to do some other maintenance.
Sorry about the video quality in advance but I think you can get the idea on what the setup is.
