    Default Pump & well question

    I have always heard that a submersible pump should be installed at least 5 feet above the bottom of the well to keep from stirring up sediment in the bottom of the well . I always assumed that it would be a good idea to install the pump at basically that level because the pump would be far enough off the bottom so that it wouldn't stir up mud & also it would be as deep as possible so it wouldn't run out of water with excess water below the level of the pump . I have filled up a thousand gallon tank with the water running continueosly so evidently my well is producing more than I can pump out of it .
    I don't know the exact depth of the well although I have been told that it is 68 feet deep . I also don't know how far the water level is below ground level . I plan to check both . After heavy rain my water gets turbid for a couple days then clears back up . I am wondering if the water level is several feet above pump level if I raised the pump level if there is any possibility that my water quality could improve as far as the turbidity is concerned or is it basically an accepted fact that all the water in the well would be as turbid as the water near the bottom ?
    If I install a granular media backwashing filter to remove turbidity is there any kind of rule of thumb as to how often I might have to change the media ?
    I would think that the more turbidity the filter had to remove the more often the media would have to be replaced . I just have no idea how well a backwashing filter cleans itself & therefore have no idea on how often I might have to replace the media . Assuming that media change is determined by degree of turbidity are we talking about media change in terms of weeks , months or years ?
    Can anyone give me a ballpark figure as to what it costs to change the media in a wholehouse granular media filter tank ? Just some type of general idea is all I'm trying to come up with . Thanks in advance .

    I will have the well tested & treat as necessary but I want to solve the turbidity problem first .

    A backwashed filter "cleans" itself on a schedule of like every 3-4 days. The amount of turbidity has no effect on the longevity of the media in the tank. You replace the media when it will no longer remove the turbidity; usually many years depending on what media is used.

    The cost of the filter depends on the media used and how much of it in cubic feet, the size of the filter that is needed (in cuft) and the brand and type of the control valve that's used, so until we spoke, I can't get into prices and types here except that the valve should be a Clack WS-1.

    CAUTION, as of Nov 12 2013 all YouTube videos showing how to rebuild a Clack valve have an error in them that can cause damage.
