About a month ago, the pipe that brings the water from the well into the house was replaced. I have a inline water filter between the water tank and the UV remediation lamp. I replaced the filter with a new filter after the work was done.
Since the replacement, our water pressure is weaker than it was before. I checked the pressure gauge in the tank and it works as expected. After two weeks, the filter got clogged. I had the well contractor come in and suggested that I should've let the water run for sometime after the work was done. I told him that I did let the water run for 5 mins. then shock the pipes, and let them run for another 5 mins and put in the filter. He said I should've let it run longer because some dirt might been kicked up during the work and that's what clogged the filter. I replaced the filter again. Now, it is two weeks since then and the filter is dirty again. It is not clogged but it is affecting the water pressure.
I brought up the issue with the well contractor and his solution is to remove the filter so the water flows freely. The problem cannot be the pipe since it is new and the pump is working fine. His other suggestions are to add a water softener or a screen/second filter that will catch the debris before they get to the filter.
My Question: what could be the cause of so much debris coming in the water after the pipe was replaced? It was never like this before even when there was a leak in the pipe before it was replaced.
When I asked this question to the contractor, his response was that "well water is never the same. It changes when it rains. Before it was clear, and now the rain must've bring dirt from the surface". While I am aware that whatever is on the surface eventually affect the water table the well is feeding from: I am not quite sure i believe this is how it works.
