Replacement Pump

[bwhitton]

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.

Thanks.

Welcome to TFP.

The 1 hp full rated and the 1½ hp uprated pumps are the same pumps.

You'll have to change the wiring to get the 2-speeds to work for you. It requires 4 wires and a switch to operate both speeds. Depending on how your pump is wired now as to how much of a change is required.

Thank you for your reply. Since I will have to go up a little in hp from what I have, do you think the energy savings of the two speed will be worth the increased cost of the pump plus the installation?

I absolutely think it will.

How is your pump hooked up now?

Not sure. I just assumed I could have replaced it with a like model myself since the pool company pulls it out and puts it in the basement. I'll have to find someone to install the two speed with the switch. I only have two skimmers and no spa or waterfall, so I figure the lower speed would be fine unless I had to vacuum the pool. I don't have to do that too often because of the Polaris.

Thanks for the advice.
