I'm sure that this is posted somewhere, but I need help in buying a new pump. I have a 43,500gal in-ground vinyl pool, 2 skimmers, a Jandy salt water generator, mechanical timer, and a Heyward 240 filter. Bought a pump from the electrical shop each year for the last 2 years that lasted only one year each (he says chlorine got in the pump and ruined it). I can't afford to buy a new pump every year. Any thoughts/rec. on horsepower/brands would be GREATLY appreciated!
