deep well pumping sand

[caulder88]

Due to a recent drought i had to extend my sub. pump 20 additional feet. Since it had to be pulled i had a new pump installed. The new pumps is rated at 18 gpm. This some what stronger than the old pump. When the pump runs continously, such as running my irriagation system, i get sand and sediment. I have installed a filter, but having to clean the filter so much is a problem. The ground water should be back to normal now. Any suggetions on how to fix this problem. Thanks

If you can raise the pump back to the original level, it may then be above the point where the sand is coming in. However, the next drought will cause you to need to lower the pump again. If the pump is running steady for the irrigation, you may can choke it back with a ball or gate valve and decrease the irrigation flow. Sometimes lower flow rates will reduce the sand amount. If the pump is cycling on and off for the irrigation, the cycling will stir up the well and make sand.

Coal Chips In My Well

My well brings up coal chips. Been 12 yrs now! I have wondered if I should consider raising the intake a bit. The good news is, the chips are heavy enough to fall to bottom of filter glass!
