    Brand new intex 3000 gph sand filter has borderline high pressure.

    I used #20 pool sand, filled it between the lines it suggested, made sure to get none in the pipe, backwashed as instructed for 3 minutes and the water was clear. Then I rinsed for 3 minutes as instructed. Then when I put it to filter it was at 10psi which is right on the line between green and yellow. After a day or two of filtering it was in the yellow. I backwashed again the same as before and it dropped back to 10 psi. My question is, why is the filter starting out at such a high psi? Is there something wrong with it? I also get sand in the sediment window when backwashing and have noticed it spitting some sand into the pool after I backwash. Not sure if that is related but unsure of how to proceed at this point.

    When you do a routine back wash you only need to wait for water to turn clear. Usually about 1 minute. Then rinse 30 sec to 1 minute. I get a little sandin pool after backwash, but less than a teaspoon. The guages are cheap and I usually just backwash when my return flow slows down from the return.

    Also my PSI was 5, but after I installed my skimmer it changed to 9psi for clean.

    I do not have a skimmer currently. I am just worried that the pump is going to be constantly working harder and it won't last as long as if the PSI was at 5 or so. Considering returning it but that seems like such a pain!

    Pumps do not really "work harder" and there is really no such thing as too high a pressure. As long as water is flowing you are fine.
