Hello Everyone, I recently purchased a Dolphin DX4 to replace my old Polaris which has a booster pump attached to pool filter. Since disconnecting Polaris from the side of the pool there seems to be a lot of air in the system and the pressure is really low. I believe the air in the system is due to disconnecting the Polaris. Does anyone have any suggestions or experience with this issue? Thanks a lot for all of your help!
