Super 2 pump with ust1202 motor died(it runs but cuts out after overheating)- 2hp with sf of 1.1. I am thinking about using a 1.5hp or 1hp motor to cut my electricity consumption. Do I need to change the impeller or just the motor and seals. I have a hayward 60sqft de filter, 2 skimmer returns and a main drain with 2 inch pvc, The pool is 30000 ig and the filter pressure measures 18 when clean. If you can recommend a source for purchase it would be appreciated as well.
