    Backwash Problem

    I just did another backwash and thought I did this correct. This time all the DE filter media/powder that I put into the skimmer all came back into the pool through my returns? Do I need to worry about this? My pool is now a milky color because of all the DE media being in the pool. What do I need to do to fix this? Do I just have to wait until my filter cleans this up on it's own? Will I need to re add my DE media again? Thanks for the help.

    I am not familiar with DE, but with sand, you must "rinse" after backwashing before going into filter mode...could that be it?

    Duraleigh - I only have 2 options. Backwash or Filter (no rinse option).

    I should have remembered that. A DE member will come along and be much more help than I was.

    Re: Backwash Problem

    Only two ways for that to happen I think.
    1 your grids are broken or something inside is not seated correctly.
    2 the o rings in the valve are leaking

    Do you think out all went to the pool or just some? Not sure it is really possible for all of it to bypass the filter.

    Re: Backwash Problem

    By the amount that I have in the pool - I bet almost all of the media went in. I'm betting one of the grids inside the filter broke as you mentioned. Pool is still covered under warranty, but it will take the pool company at least 7 to 10 days to come out.

    If you want, open the filter up and take some pictures and forum members may be able to help.

    I won't be able to work on this for a week myself - I'm traveling. I will have to wait until the pool company fixes it. I was hoping it was something that could be done quickly.

    Re: Backwash Problem

    This is going to be a badly mangled grid or a totally bad backwash valve. Let the service company deal with it.

I think the practices regularly espoused on this forum (especially the BBB method) are outstanding; however my comments will be often oriented towards the goal of getting it done, and getting it done right now!
