I have a 20,000 gallon inground pool built in the early 2000's run on a Jandy Aqualink RS16 controller and has a Spa with jets and spillway waterfall, 500 sqft cartridge filter, rooftop Solar, propane heater (for Spa), 2 waterfall pumps. All the pumps are single speed from the early 2000s. Only the filter pump and its robot pressure pump operates more than a short time.
