Intex Pool Filter High Pressure

[o_tiagosantos]

Hi Guys,

I bought a Intex Sand Filter with 0,75 hp, my thing is, i have a above ground pool, concrete one, with 4meter by 4 meter and 1,40 of depth.
I install the pump but the pressure is always high, the pump works perfectly, the outlets and the inlets ports works with a big flow of water.
But what scares me the most is when i turn on the pool the filter expand a little bit. I contact the intex support tem and they said to return the product, but i want to understand if this is normal or not cause the filter is working great.

Video of the pump expanding:

What type of sand did you use?

My findings on how not all sand is created equal

Ok well today I finally got all my parts from Intex to fix my problem I was having with my sand filter. Here is a link to that thread which I will update as well http://www.troublefreepool.com/threads/101906-New-Pool-Intex-Customer-Service-Long-Post-lol So basically for the sake of this thread...

Hi,

I use glass media 0.6-1.2mm, its a little bit bigger that the manufacture recommend, but if its bigger create less pressure right?

I think the glass media can be your problem.

I think the glass media can be your problem.

Really? Should I change for sand or reduce the quantity ?

Dunno. You can scoop some out and see if it makes a difference before you totally change to sand.

I will, thanks

I take some glass media out but everything is in the same

My Bestway sand filter always ran pressures like that, I was using Clorox sand because it was all I could find, a bit less than the total recommended amount.

I think the green marking on that gauge is just a bit hopeful, 10psi would be what you'd expect from a full capacity well designed sand filter I think the Intex/Bestway stuff just doesn't perform as well. My gauge didn't have color coded ranges so I just said ok that's the clean pressure for this filter and it is what it is.
