yesterday I received two flare nuts so i could make the little bridge. Were normally a solar collector would be placed.
I also made my first flare connection i did a small test i pult a vacuum and after one day the analog meter on the manifold haven't changed. To morrow i can pick up the bottle of nitrogen so i can do a small pressure test on this small circuit. And i can also starting to braze the rest of the components. I only have one service valve do you guys suggest to ad a second on the other line?
