Long story short,, I have a 4 inch pvc well that we oversized the slots. Its 61ft deep with 25 ft of slotting. Static water level is 25ft below the surface giving us a good colum of water to work with. Getting sand and or small gravel(some sticks in the pump inlet} in the submersible pump and locking it up. We have blown this well with a 200cfm compressor 3 times letting it blow all day long,starting and stopping. The water never gets nowhere near clear while blowing, but there is alot of it, aprox 20+ gpm. After reinstalling the pump and a few hours of running the water will clear up some but will sand lock after a couple of days.We have the pump about 10ft off the bottom and the sand is filling all the way up to the pump. So, here is my fix. Tell me if you think it will work. Replace the submersible pump with a deep well jet pump. On the drop pipe use a sand point with a check valve insted of a regular foot valve. Im thinking this will keep the sand out and still give us a good flow even if sand fills up above the sand point. I know it will be less flow than a submersible but maybe it wont stop after a couple of days. Yall think this will work? Thanks for all your help.
