Thanks everyone for your responses.

I may have messed up today. I ordered a UR 2 speed 1 hp WFDS-24 Whisperflo instead of the Superpump because they had it in stock and I could have it by Friday. I normally don't get a hurry about these kinds of decisions but I wanted to work on it this weekend.

Now my new questions:

Is the Whisperflo a decent model?

They convinced me it is much quieter than the Super Pump. Do you think that is correct?

I noticed the web says it is a 150V instead of 220V. Can that be right?

It also has 2" intake and outflow. I guess I can buy reducers to go back to 1 1/2" with little problems?

If I stay with 1 1/2" pipes throughout the max flow is 42 to 44 gpm so I don't really have to worry about too much flow to the filter right? I believe my current filter is 62gpm max. The tag is so old I can barely read it.

I hope I don't kick myself for this one!!!!
