I had my well dug 60 feet deeper last fall as it pumped brown. This is a seasonal home and was not used from Nov till April. The water is clear but still a little sand. Wife filtered thru a coffeefilter and in a gallon there was tiny amount. I have been running the water out of the tanks bottom and it hass made no difference in fact sometimes it is worse. What to do? leave it alone and see if it resovles or get a new tank or get a filter? If a filter installed before or after the tank? Can I flush the tank and if so how is the best way . Fell nervous about this maybe will lose the pressue. It is a well mate WM6. Any help or advice is appreciated. tony
