P.O.C. at Existing Mainline

Jon,
You only need one POC type. If you are tying into an existing pipe size, that is typically where the POC option comes in. Assuming you have different readings at each of the 5 tie in points, you could set your 5 different POC sources and place at each tie in point. Keep in mind that if the mainline is looped and all POC's are connected in with each other that the system is still going to only size one POC at a time.

Any further questions with this, just let us know and we can go from there

Thanks Jake. I'll remove the Water Meter and only use the POC type. It seems like I'd need 5 POCs because I have 5 new zones all connecting to the existing 2" irrigation mainline at different locations even though the static water pressure is consistently 60 psi. Otherwise, I won't be able to run a Critical Analysis for all the zones. What am I missing?

Sounds like you have it. Placing 5 POC's is ok, especially if that is where each zone will be getting the water (at each different location, not connecting to each other from a single point. The system will be able to distinguish between the different POC's when sizing, just follow the prompts at the commandline and all will be well!

Keep us posted if you need anything else and we would be happy to help you out.

Cheers,

I would do it like this:

Use the meter, since that is your source. All hydraulics depend on it.

Assign a main line pipe class that connects to this meter, and set its minimum size to 2".

Assign a second ML pipe class to branch off the first ML at the points where your new "POCs" would be. These aren't actually POCs in the LFX sense, they're just places where you branch into sub-mains. I imagine you'll have iso valves and maybe backflow devices at these points.

After you design all your zones and size everything, size the ML. The CA will show all demands from the meter and on downstream. You can adjust the sizes of your zones if any are so large that the system tries to up-size your existing 2" main.

Make sense? Am I missing something?

Thanks Tom. I set up a "dummy" meter and mainline and re-ran the CA as a check for multiple POC approach I discussed with Jake. I'm happy to report that both approaches were within 2-4 PSI residual pressure available of each other when I ran the CA. This gives me confidence moving forward. The only downside is that once I changed the POC info, it over-wrote it in my previous design file despite doing a "save as". Not the end of the world just caused me a bit more time to redo.

I appreciate the fast response on all this. Very timely and helpful!
