Good Morning TFP,
I live in Indiana and am excited to get started on a new pool project once the weather breaks....assuming it ever breaks. I am installing a Pentair Thermalflo heat pump and a hayward sp3400vsp pump. The heat pump will be an addition while the pump will just replace the Hayward single speed pump which is on its death bed. Both new units have 2" unions. My inground pool has 1 1/2" pipes. The sand filter I have is 1 1/2" unions.
My runs are less than 60 feet. The longest run is the skimmer line which is 51 feet. I know I will need to use reducers in my piping, but since I am in planning mode, I'd like the Forum's expertise to know where they should be fitted. Feedback can be conceptual or precise. I would like to maximize the cost savings with the variable speed pump but I am aware of the pressure requirements of the heat pump. I don't want to set up a system that trips off the heat pump (due to low pressure) just because my design was poor or ineffective. Any help would be greatly appreciated!
