Not sure if I'll be able to explain this clearly, but here goes. I have a 10GPM centrifugal well pump on my 800' deep, 10 GPM flow rate well. There is a hydrant on a tee on the top of my well -seal. From that tee, the water line continues underground and under a lot of concrete, into the house where my pressure tank is located. I have a Cycle Stop Valve immediately before the pressure tank (see attached photo). The only way I can currently irrigate in my yard is by using hose bibs around the house. My house is on a slab. Bottom line is I have no way to add an irrigation circuit to my plumbing system without lots of concrete cutting and that's out of the question. OK, please hold those thoughts.
So, as I mentioned, I have a hydrant on a tee on my well-seal between the pump and pressure tank. When I open the hydrant and the pump is not running, water comes out of the hydrant slowly (see attached video). I'm guessing that the pressure tank is pushing water back out of the pressure tank.....through the Cycle Stop Valve....down the supply pipe..... until it comes out of the open hydrant. Once the level in the pressure tank drops to the point that the pressure switch is tripped on, the pump then begins pumping and the first exit available to the water coming from the pump is the open hydrant, and the water gushes from the hydrant (see the second video) without ever reaching the pressure tank in the house. In effect, the water flow direction reverses from the pressure-tank-to-tee/hydrant-to-pump direction to pump-to-tee/hydrant direction. So, if the hydrant is open and the pump is running, no water reaches the house.

Is there any way I can adapt this configuration that I have so that I can both use the hydrant for irrigation and ensure that while irrigating, I am also able to supply the house with the water needed for daily activities and be able to do this without burning up the pump? One thought I had is maybe I could add another Cycle Stop Valve between the tee on top of the well-seal and the hydrant, with the thought that the Cycle Stop Valve would restrict the flow to the hydrant to only what is being demanded by the hydrant, and the balance of the 10 GPM being pushed by the well pump would bypass the hydrant and flow to the house......but I don't know if that's realistic or not. Any advice would be appreciated.

The CSV cannot control any water that doesn't run through it. All you need to do is move the CSV to the well head. Install the CSV off the tee on top of the well and connect the hydrants after the CSV. There is even a 3/4 port on the bottom of that CSV1A that you can use for adding a hydrant. You can also use the two 1/2" ports on the CSV for hydrants, but they are small and won't supply as much as the 3/4 port. You could also replace the elbow after the union with a tee, and come off that tee with as many hydrants as you want. The hydrants just have to be after the CSV.

Thank you, Cary. So, by moving the CSV from its current location at the pressure tank out to the tee on the wellhead, before the hydrant, when I open the hydrant valve, will the initial flow volume from the pressure tank to that hydrant now increase to something comparable to what I see coming from a hose bib on the side of the house? Am I right that with the current configuration, when I open the hydrant on the wellhead, before the well-pump comes on, water flowing from the pressure tank to the hydrant is having to pass through the 1 GPM dribble orifice of the CSV, thereby restricting the flow as shown in my first video? But after I move the CSV to the wellhead, before the hydrant, the CSV will no longer be between the hydrant and pressure tank restricting the backward flow towards the well, and the flow from the pressure tank to the hydrant will be unobstructed and the flow rate should be similar to what I experience when opening any other valve in the house. Am I right about that? And I guess, this move will also eliminate any backpressure stress in the buried water line between the well and the pressure tank in the house, and limit the 160 psi backpressure to the line going down the well, is that also correct?
