Just cut the line prior to the tee to the yard hydrant, and plumb in the CSV. It is no harder than adding another tee in the line.
Leaks while you are away can be a big problem. I am using the Samsung Smarthub with an Aeotec heavy duty smart switch to turn my pumps on and off. I have leak sensors in all the appropriate areas that will shut the pump off if they get wet. It also lets me program on and off times, like the well at my shop comes on at 6:30AM and goes off at 5PM, regular business hours. And I still have the leak sensors in case there is a leak during the day before I notice it. I am working on a way to use this switch for pump protection as well. If you are interested let me know and I will give you links to the components listed above.
