    sand filter problems

    I have an above ground pool 15000 gal., 1.5 h.p. pump, 200# sand filter. when vacuming dead algea from pool it just passes through filter. I tried putting D.E. in filter, but it seemed to pass through also. I changed the sand earlier but still have problem

    Re: sand filter problems

    welcome to TFP.

    What is the filter pressure?
    Do you have a multiport or a slide valve?
    If you ave a multiport, is the valve set to filter and not to recirc?
    When was the last time you opened the filter?
    Is there any leaks around the filter?
    Is there any water leaking through the waste port?

    Welcome to the forum.
    opened & changed sand week ago
    Did the filter do this prior to changing sand?

    Re: sand filter problems

    In all likelihood it's probably the multiport valve bypassing internally.
    Have you taken the top off the valve and inspected it?

    Re: sand filter problems

    Reinforcing bama's post, it sure sounds like your multiport has an internal problem allowing some of the unfiltered water to go back to the pool.

    Disassemble the multiport and inspect it for any visible sign of a problem. Particularly, the spider gasket.

    Re: sand filter problems

    It would be great if you'd put your pool and equipment info in you sig. That way we don't have to look for it in a post.

    Once you take the top off the multiport valve it will probably be obvious what the problem is if there is one.
