    What do i need here?

    Every time i vacuum my pool floor clean, shortly after it has very fine yellow/brown particles that have dumped themselves back onto the floor via the wall ports. I vacuum, then backwash, then turn the pump back on filter, and if you go over and look at the jets, you can actually see the discolored water and small particles being dumped back into the pool - very frustrating! Where can i find a vacuum or pump that i can use to just suck that stuff off the floor and directly into the backyard, completely bypassing the pool's filter? Any thoughts?

    What positions or "settings" do you have on the valve on your filter?

    When I vacuum, the valve is set to filter, then I turn it off and take the vacuum out of the skimmer and turn it on backwash for a few minutes. Then i turn it off and set it to filter again for normal use. that's when the junk flushes back into the pool. I think i've tried vacuuming the scum in waste mode too, but i remember that it still seems to come back in through the wall jets...

    After you "backwash", put the filter on "rinse" for about 60 seconds or so. That should eliminate or minimize the blowback into your pool.

    hmmm, never used the rinse mode before. I'll try that this evening! Thanks! Also, where can i find instructions to open the sand filter? Is it easy to do?

    Re: What do i need here?

    so for this situation, are these the steps?

    vacuum to waste
    backwash
    rinse

    or do you rinse then backwash?

    Hello this is the standard procedure.

    vacuum on filter,
    backwash till water is clear,
    rinse for 20 or 30 seconds,

    If you want you can vacuum to waste, but you will lose a lot of water.

    Also you don't have to backwash everytime you vacuum, [in fact it's better if you don't] only when the pressure gauge goes 8 to 10 psi above what it is just after back washing
