Hello everyone, I have an 18' X 52" AGP. My pump is not working propertly, the mechanic told me that the impeller is broken and the fix will cost me almost half of the cost of a new pump so I decided to buy a new one. My pump is a Waterway Clear Water II 100sqft Cartridge Filter System with 1.5hp Pump 2 speed. My question is... should I buy the same pump or is there a better pump than this one on the market? Please I need your advise asap. Thank you.
