I am planning on adding a second line to my private sumersible well, This line will be about 6 feet from the well head. My thinking is I will put a tee on the current well line to home and then off the tee and run 300' of 1" PVC line to a waterier for the equine. Right after the tee I will be adding a shut off valve to the new line.
My question i---s when I tie into the existing well line to house do I just power off the pump...cut the water line...insert tee fittings..connect new line and valve...power up and all is good or will I have a prime issue when I cut the main line? Also this is prior to pressure tanks so can I even do it the way I want?

I can't say as to priming the pump, but when you install the new line, most glues have a minimum set time for pressure applications. Make sure that you observe this. In addition, you may want to consider adding a rpz when you add in the line for the horse waterer. Personally, I wouldn't want to drink horse slobber if you have a pressure loss at the pump and water back siphons into your house supply.

There are so many unknowns about what you are planning to do that it is impossible to make a recommendation. On the surface, I would say you CANNOT do it, unless the line from the pump is ALWAYS at the same pressure as the house, which is seldom the case.

If there's no check valve at the pressure tank, you can place the tee where you want to.
If it's a submersible pump there's no need to prime.
Just shut the power off to the pump, drain the water best you can and cut the pipe, insert the tee and valve and repower the pump.

In order to meet code, you will need to install at a minimum, a double check valve, maybe even an RPZ at the waterer. It will have to be accessible for service. If there is a check valve at the pressure tank, it will need to be removed. Typically, you will not be able to just 'slip' a tee into an underground water line; you'll probably need to install a union as well.
