    Automatic Pool Cleaner screen keeps clogging

    Hello there,
    The problem I am having is that the small screen which is in the line supplying water to the pool cleaner always gets clogged after a day or so so every day it has to be cleaned or the cleaner will stop functioning due to lack of pressure. So this got me thinking... In my pump/piping setup you can see that the pressure out to the pool cleaner is before the DE filter. I was wondering if anyone sees anything wrong with capping that out flow pipe right after the Jandy valve and installing another jandy valve after the DE filter to supply the pool cleaner with filtered water so the little screen doesn't get clogged so often. Only reason I can think of is that there may be a pressure decrease, but I think it will still work fine. I also thought of installing a larger type of filter/screen in-line to the cleaner, I just don't know what I'm looking for.

    If there are any other ideas out there, it will be greatly appreciated.

    Thanks,

    4) plaster

    Don't know flow of filter, but the DE Unit is 2ft diameter and about 3ft tall (kinda egg shaped).

    I have no idea about the pressure drop and all that, but it certainly seems counterintuitive to return unfiltered water to the pool, especially to clean it!

    It seems to make sense to supply the pressure cleaner with filtered water so I would say yes, plumb it after the filter. What material is clogging it so frequently?

    small bits and pieces that pass through the skimmer basket and the pre-pump basket.

    Sounds good. I don't know who the hec installed this system this way, but I'm in agreement. It just doesn't make sense to me.

    Thanks again everyone. I'll report back after this is done.

    Well I just want to say thank you to everybody who chimed in on this little issue I had. It turns out that normally a booster pump is used to supply the pool cleaner with water pressure but the person who had the house before took that part out of the equation and just plumbed into the system which works fine now. I don't really see the reason and having a booster pump , it works for me, ymmv, as my pool isn't that big really.

    again, thanks to everyone.
