    Water shoots out of return like a geyser

    Hello, I am new to this forum and I have been researching on how to hook up a sand filter to an Intex above ground pool. The pool my family owns is small, about 15'-16'. We recently bought a Hayward sand filter, 16" filter tank with a 1.5 hp pump. Originally, amazon said it was a 1 hp pump but on the pump it's labelled 1.5. I'm afraid it might be too powerful? When I hooked it up to the pool, first I tried with the hoses that were supplied with the pool originally, water was shooting out like a geyser out of the return. Is there any way I can reduce the water pressure? would hard plumbing it with valves to control water flow into the pump work? Any advice would be helpful!

    Welcome to TFP Sabrina

    It could, but the pump still might push things through your sand filter and that is the real problem here. You simply may have too much pump.

    You don't want a valve to cut down water flow into a pump, it needs to be on the output side to reduce outflow. Restricting flow into a pump can cause pump damage.

    As a licensed plumber I would say way to much probably only need a 1/2 hp and at max 3/4 hp
    IG gunite/plaster 9,200 gals-with 7x7x1-1/2 splash pad with bubblers.
    3/4 hp hayward super pump for bubbler and water fall-1 hp hayward super pump for filtration
    24" hayward sand filter.

    Yep. Too much pump. I have a 1.5 hp pump on a 34K gallon inground pool. Can you return the pump? I know Amazon has always been good to me about returns. You could put a valve on the outlet of the pump before the filter to slow the flow, but my biggest concern would be the extra electricity you are burning with an oversized pump. Of course, you shouldn't have to run it too long each day, so the actual $ amount is probably negligible.
