Keeping sand and silt out of pressure tank.

Pressure tank for my well keeps getting sand and silt in it. We are able to keep it out of the rest of the system with filters. A few days ago I installed a 1.5" ball valve at the bottom of the tank, Connection to the pump and rest of the water sytem is at about 1.5Ft above the bottom of the tank. The idea is to open the valve every week or so and flush out the crud. Probably should have asked before I did it but is this a good idea or should I have done something else?

The house was built in 1973 and the origonal owner had the same problem. His solution was to pump water from the well to a several thousand gallon cistern allowing the sand to settle and then use a shallow well pump and presure tank to take the water on to the house. Maintaing the cistern is something I did not want to do.

Check at a plumbing supply house for an in-line strainer that can be installed before the pressure tank. One style has a ball valve at the bottom that can be used to flush the strainer.
