Sudden clay like sediment in well water
We have had clear water for over three years from our well. We changed our filter once every three months. Starting a couple of months ago we noticed that we were having to change the filter more often. Suddenly we went straight to a clogged filter with tons of grey sediment in our water. We let our well settle using our neighbors well instead of our own. We turned our water back on today and the water was clear without a filter on it. We let the water trickle out of the hose all day. We flushed and used it for washing dishes etc. I even did a load of laundry and still clear. I went to give the baby a bath ands suddenly it turned all sediment filled again. Do we just need to cave and get a high priced ultra filtration system or is there a problem with the well that can be fixed. My neighbor has the idea that maybe we having a split in our piping or joint that is praying the well sides and stirring up the water. Is there anyway to know if this is true. He suggested a pressure test. I have three kids and am finding it more and more tempting to just throw my monwy to a water system to treat the problem, but I don't want to spend money where it is not needed. I can't understand how these drastic changes could have suddenly taken place with our water. any help would be appreciated!
