If I have a 1.5hp swimming pool pump, can it work OK as an above ground
pump
on sprinkler system?

I would guess not. While both pump water, the purpose of both is totally
different. I suspect the GPM rating of a swimming pool pump would be way
below that required of a sprinkler system pump, even if they have the same
HP rating. After all, the swimming pool pump is just circulating, not
moving water from point A to point B. Don't need a high GPM rate to
circulate water, DO need a high GPM rate to irrigate something.

However, if you've got a spare swimming pool pump (that you'll never need
for any other purpose) and you need a replacement pump for a sprinkler
system on the cheap, there is probably no harm in trying it out. At
worst,
it won't work...or it might burn out the swimming pool pump. So I'd only
suggest you try it if you've got a spare pump that you don't mind ummmm,
burning out. -Dave


You may be able to get it to work, but you need to do more research and
design. If it's a high pressure, low volume pump you would need to add one
or more pressure tanks, sized so that the pump runs for up to about two
minutes whenever it comes on. If it's low pressure, high volume then you
don't need the pressure tanks and the pump can run for as long as the system
is turned on. But you also have to worry about whether there is enough flow
to keep the pump from overheating --

If you stop by a good irrigation supply company they can probably help you
sort out what you have and what you need --
