Size system - closed loop issue

Hi Luis - Can I check - is the cross hair appearing where your floor change connector is?

Regards,

Hi Duncan.
Yes. It's in the floor connector.
Thanks for you help.

Hi Duncan,

Followed your instructions. System seems ok on isometric view but now reporting "No flow in pipe on floor 1" and pointing to the floor connector position.

Let me know your thoughts

Thanks

Hi Luis - a "No flow" message indicates that you have an open ended pipe in your system. You should try and determine the pipe (run a calculation, it show the spot the error occurs), delete it and redraw it, ensuring your snap to existing pipework.

I think I found the problem.

I've deleted the pipes in the first floor to draw them again. 1st floor network is at 0.15m (low level), so i started by drawing the riser from 0.15 to 0 selecting "special" and setting it to 0. This would trace the vertical pipe between floor connector and required network height.

After drawing it I've used the pipe info tool and I'm seeing it being 0.075m instead of 0.15m that I need, hence the open loop.

What am I doing wrong in this case? (zoom of 1st floor connector below and pipe info.

Thanks

I've done it.
Deleted again, just drew a pipe from the network to the floor connector and it automatically added the riser and I was able to size the system.
Thanks again

Luis - <edit> I can't think what you may have done, other than enter in the wrong numbers when drawing the riser.It will take whatever figures are entered.

When you select a pipe it shows you the mid-point of the height, rather than the top or bottom of it - the mid point of 0 to .15 is .075. 

I would suggest group deleting again, and redrawing. What you could do is group delete again around the floor change connector on floor one and draw one of your horizontal pipes right into the floor change connector. In this case, it should add the riser automatically.
