Hi mate,

I think you have to change a little bit the design. I am sure you know that the water always choose the easiest way. In your case i think is the pipe with the smooth angle(the last of the 3).
It will be better if you do sth like that

Also the customer will have to use the same length pipes for connecting the blocks and same with same restriction.
Using blocks in parallel is a little bit difficult.


And at last I suggest to make a tank because your pump is really strong so with T it will be almost impossible to remove all the air from the loop.
