I have a project where we are keeping part of an existing irrigation system (on slopes and looped) and adding new mainline to the rest of the project. We are keeping the valves within this existing mainline as-is and adding a few more new valves to fill in some gaps along the existing mainline. Since this mainline is already 'sized' and 'classed' is there a way to force Land FX to keep it a specific size and pipe class and not auto-switch class type or pipe size?

Luis,
This might be something better suited for a tech support ticket. We can then discuss over the phone your best options once I understand what exactly you are trying to achieve here. I will create a ticket on your behalf and give you a call to discuss further.

Steve,
Here is what you wanted to know:
-Project is actually a retrofit job, previous design is old (not done using Land F/X) and already in the ground.
-New design is being tied into the existing mainline.
-Old system is maxed out and completely under designed.
-Client wants to leave old system in play, even though it is really under-designed.

Suggested to use the POC option and place where they are going to tie into the system. Using Land F/X will make sure the design is within operating range of what is available, the only additional step that would be needed is to make sure they have enough residual pressure to handle the friction loss through the existing mainline.

Other options could include the use of Caps for the existing zones and place the Meter where existing and size entire system so they could have a proper conversation with the client about getting the entire system up to an acceptable operating condition.

Hope that helps!
Aww. I want to know how to deal with this situation too. Maybe just a bullet list of what to consider.

Jake,

Thanks for getting back to me so quickly. I'll try out the options we spoke about on the phone and will follow up on the ticket.
