Hi, does this look right? I think the pump should be moved to between the air separator and the manifold (does it matter if vertical or horizontal?). The installer originally put it between the dirt magnet and boiler, but I told them I designed it to pump away. It’s a Noble 110, with alpha2 pump to cast iron rads, each equipped with TRV. Any other things I should look at? They had never put a home run system with TRV before. I designed this with help from many of you, so thanks
