Would a 1 1/2 HP centrifugal pool pump work to pull water (aprox 3 - 4ft in
elavation) from lake for watering lawn and garden?? RM~

Depends on the pump. Some will. Elevation is one factor, but distance can
be too. Are you talkign having the pump right above the water or sucking
through a hose that slopes that 4 feet elevation over 200 feet away?
Be sure to put a foot valve on too.

I purchased it at an estate sale, thought it was a shallow well pump
until I got it home and read the fine print. Duh!
Anyhow, don't have a real big investment ($10) but it's in a like new
condition. I had planned to set pump in a storage building about 20ft
from lake and I doubt the rise in elevation is much more than 3 ft..
Thanks to all who responded, Rob Mills
PS, It's a Dayton 9K614 1 &1/2 HP 110/230 volt pump. Actually
it looks husker than the shallow well pumps sold at HD and is not
made of plastic.

A above ground pool pump is below the surface level of the water
so that that type of pump need not be good at creating a vacuum
at the inlet.
I would think that that type of pump would have a difficult time self
priming at four feet. Try to locate the pump as close to the level of
the water as possible.

Yes, I think that's right.
I use my pool's own pump to empty it when that needs to be
done, and once it gets started, it has no problem draining
it all the way down - six feet plus maybe a foot the pump is
elevated above the top of the pool. But if it ever loses
its prime, it can't get it back beyond a foot or so down.
When it's driving air, the pump's impeller just can't create
enough vacuum to lift water very far.
But may should work ok if you put it close to lake level and
let it push the water uphill.
