So my pump died yesterday and I am having a hard time figuring out what to replace it with. I am running a Hayward S200 filer and need something that is compatible to that. The pool store is trying to sell me a 1 HP Hayward SuperPump. The pump I had was so old and the casing so corroded they think it was 3/4 HP. I need to know what I can replace it with. Possibly a the 1HP superpump is best or should I opt for a Hayward SuperPump II or Tristar.
