Hi Everyone! Steve Cook mentioned this might be a question for Jake...

I'm currently working on a multiphase project, and hit a bump on the road regarding irrigation. I have my irrigation meter located in Phase 1, and I've placed two stubs leading to Phase 2. Now, in Phase 2, I need to connect to these stubs, but I'm having trouble trying to run the two stubs simultaneously to ensure a looped system.

The LFX website mentions that I need to place two gate valves at the middle point, but that's not quite what I'm looking for since this setup is meant to be a looped system. I'm looking for a solution that allows for me to simultaneously operate both stubs as if they were a looped system connecting to Phase 1.

Thanks in advance for your help!

Nancy,
Thanks for reaching out. I think it would be best if you sent in your drawings using our Technical Support tool, and we can converse there so I can see the example and we can hash out a workflow there. We can then post here with our final result for those that stumble across needing the same help. Please use the link below for steps on how to send us what we need and we can go from there.

How to Submit a Technical Support Ticket
Thanks Jake. If we are doing a TEAMS meeting, please invite me.:D
To elaborate a little, our original design was not phased, and we had enough pressure to serve everything since it was a looped system. But when we design it using isolation valves as is mentioned in the LandFX documentation we start sucking air (JK, but you know what I mean).
I attached a graphic for reference, Nancy may send more.

Thanks Jake! Just sent the drawings over using the technical support tool. :)
It was determined that to calculate the flows and sizes correctly on a looped system, the whole system must be done at once. If you have not designed all of the phases, one can add pipe caps for future use along points in the mainline (for multiple phases), or at the furthest point on the mainline from the POC. That will set the minimum pressure and flow requirements for the loop. Then set up the separate phases in distinct work areas so you can run your schedules. You can show isolation valves at the phase lines.
Then use AutoCAD and use irregular viewports to show the distinct phases. If you want to show the adjacent phase screened back, you can bring in the irrigation base as a duplicate and screen it back. To do this you cna bring your irrigation base drawing into the paper drawing. Then rename it so tat you can bring it in again (AutoCAD needs to have separate names for xreffs). Let me know if you need more help with this.
