The WhisperFlo is almost certainly too big . . . unless you get at least a 24" sand filter.

Manufacturers play games with horsepower ratings. A 3/4 HP Whisperflo will probably push more water than a 1.5 HP Powerflo, and will push the dirt THROUGH the filter, if you don't mate them properly.

Look at the differencee between these bulkhead fittings:

Hayward SP1023 bulkhead fitting
Hayward SP1023G bulkhead fitting

I think you want the 2nd one. Here's the Hayward manual, and a PoolCenter page that explains more. Depending on shipping costs, the Pool Center may be cheaper, too.

Please let me know which bulkhead you use, and it works.

PS: I'm still working this page, but you may want to look at it and this one, to see what I mean about HP vs flow vs filter capacity

Uh-h. Hi Pappy. Didn't pay attention to who was posting.

The Whisperflo IS too big, but you should be able to run it on low, virtually all the time. You'll probably need to put a throttling valve between the pump and filter. If you adjust it to avoid excess flow on high, it will have no effect on low, but will keep you from accidentally blowing all the sand out during backwash.
