Hi,

I am currently trying to size the pipes of a heating system with radiators on PiscesPro. However, some of the nodes on my return pipe are coming up as having no downstream connection I was just wondering how to rectify this?
I was also wondering what was the correct way to finish the return pipe once it has returned to the plant room, I have it piped into the other side of the pump, is this correct?

Thanks in advance.
