Everything is ok, the only doubt I have is that I wanted to check from the central screw even though I could hear the pump running, but when I tried to unscrew the screw I saw too much water coming out, so I didn't unscrew it. This doesn't happen with other pumps, I assume it's because it's new, at least I want to hope so, since every year when the heating starts I check them all because, as always, they get blocked by limescale.

Looks good, not assembled
