Thanks for the confirmation.  Figuring the back pressure from a CSV is fairly easy.  Subtract the static water level from the pumps shut off head and divide by 2.31.

Okay thanks. I decided to throw on a pressure gauge while installing because I hated not knowing for certain and it does in fact sit at 97 PSI! Quite surprised to be honest, I figured there would be losses somewhere to the CSV but here’s to more validation for you!

Thanks again, so far it works great.

The burst pressure of pipe and fittings is 2 to 5 times the rated pressure. So, no I am not worried about it.  Actually the back pressure from the CSV is easier on the pipe and fittings than without a CSV when the pump is cycling on/off and causing water hammer.

Thanks for helping out! Looks like I am under but with little margin, would this concern you with your experience?

That is actually a pretty good well record.  It shows a 7 GPM, 3/4HP with a static of 175'.  100 PSI pipe is very low rated pipe but, I calculate the back pressure at only 97 PSI.

I purchased the psidekick based off my well report (not installed yet), seems like it meets the parameters allowed as long as I understood my report.

Now I didn’t think about back pressure and the piping/fittings I have and whether the rating is exceeded. Can I determine back pressure with the information in my report? I started to get concerned since the brass barbed fitting I’m going to use in the black underground cresline pipe is rated for 100 PSI. Will try to see if I can make out the cresline rating on the pipe.

Appreciate any help in advance.

Edit: incoming supply pipe is 100 PSI rated as well, can’t find specs on the pump, not under the well cap. Installed in 1990, location is Maryland.

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.

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!

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.

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
