I currently have a Jandy Max HP 1.0 (MHPM1.0) that I am having troubles with and would like to replace. This model was discontinued and replaced by a Jandy Plus HP 1.0 (PHPM1.0). I am considering getting a two speed but would like to know whether it is worth it and which Jandy model to get. The Jandy Plus HP has a full rated 1HP in a two speed or a 1.5HP that is up rated. Which do I choose? My current pump is up rated. Also, will I be able to swap the old on out with the two speed without any wiring modifications or do I need someone to install it.
