HI All,
I want to get a 2 speed pump to try and save some energy costs this year but have a question regarding the low speed portion of the pump. The graph is here,

If you look at all the low speed pump numbers none of them flow any water above 30 ft of head. Does this happen in the field? If so, my notion of running my inground pool that probably has an average of 60ft head is flawed and I'll only waste money paying for a 2 speed pump I won't use.

Anyone care to explain?

Thanks!!
Joe
