I'm trying to pick out a pump for our pool and I've run across some posts saying that the Hayward SP was very noisy. I'm going to purchase a 2 speed 1 hp pump so I know it won't be as noisy as a 1 speed, but I still don't want to get a pump that's known for being loud. If they are noisy, is there a different pump that's quieter? Thanks..Denise
