The well filters are filling with silk and sand there's water pressure but no water flow what can be causing this?

Heavy sediment in your filter is usually caused by well pump being to deep and coming into contact with bottom of well.

Raise pump about 2 feet and this should clear up that problem.

If your filter has that much sediment in it, you will have to change the filter and also clean the aerators on the faucets. If having trouble with toilet you will have to flush the filling system.

This could be caused by the well filling up with soil. You're going to need a pump guy to come and check it out. Good luck. Tom
