sediment filter question

[ps95]

Hello there, I have a cycle stop valve installed in my well house. The pictures below are located in an attached garage. When I replaced my large failed tank with a smaller one, I noticed that it was filling up with debris. I put a sediment filter in between the pressure tank and the vertical Tee coming from out of the concrete. Is this okay to do?
Thanks

Shouldn't be a problem.  A filter before the CSV will have high pressure and must be rated for 125-150 PSI.  A filter after the CSV will only see the 40/60 same as the pressure switch setting.

You might also want to pump out the well.  A big valve or multiple hoses open at the same time to move a high volume of water will bring the sand out with it.  Some wells need to be developed like this for hours or days, but then never make sand again.  Usually the well was just never developed properly to begin with.

Thank you, Mr. Cary, for your knowledge concerning all things plumbing and Cycle Stop Valves, as it's a relief to hear that. The clear sediment filter has a 100 size mesh filter on it. Should I leave it or install something with a larger sized mesh, like a 30 or a 40? While it's not sand, it's more like magnetic reddish colored fragments that are about 1/16" on average with some a touch larger. I did let the hose run for a good while after I had the pump pulled due to wires rubbing on the casing. Definitely could hear some bits through the lines!

One hose is usually not enough flow to get the well developed. Big chunks sometimes pump out easily. The smaller the filter size the sooner it needs cleaning. Sizing the filter to what needs filtering is best.
