We had our pool installed in 2009. It's used 4 months of the year. We had it opened today and the pump doesn't work. It just hums. I checked the impeller and it cannot be budged so I don't think it's the capacitor. Gave it a few taps with a hammer too. Nothing. We had to have the pump motor replaced once already two years ago. So assuming it needs a new motor this will be the third pump in 7 seasons of use. Or put another way, 28 months. Is this an install issue or am I just getting lemons? It's a Hayward Superpump 1HP.
Secondly, my wife hates the noise that comes from it anyway. Can someone recommend a reliable and quieter pump? Do all energy efficient pumps require more wiring that what I have for a single speed? Thanks.
