4) Use the Block number slider to change the relative size.


Re Order : 
After you have developed many blocks in a design, the blocks may not all be in visual numerical order. Use this function to define the numerical/visual order.
You will start by pointing inside the block that should be number 1 and then continue with all the other numbers by pointing inside the desired block.


Irrigation Legend :
This function will create a legend of cad lines that represent the pipes used in the design. It will also define cad text elements for the pump, valve etc with the symbol representing each node type.


Automatic pipe sizing has been improved and more economical pipes are selected.


User defined bom with selected part numbers.


Use the Combine document option to accumulate the reports into one document. If the Add Reports option is checked, then each time a report is run the result will be added to the contents of the Combines document.


Copy screen. : Will copy the current screen to clipboard at double the screen size resulting in a higher resolution bitmap.


Use the Show and Hide options when developing the design. Hide all the other blocks so only the one you are working in, is displayed. Show all the blocks again when switching to another block.

IrriExpress Add a Block - Help Tutorial

Posted on February 02, 2016 by Susanna Whitford

How to Add a Block

Blocks are used to create layouts of emitters or drip lines. Blocks are used to quickly fill a designated area with sprinklers or drip lines. A valve represents the blocks requirements and connects it to the mainline. The pressure and flow in the valve is determined when the hydraulics are run for the selected block.

Block with Solid Set

To create a block, select Block on the Irrigation menu.

IrriExpress Irrigation Software

Draw the points of your block on the workspace. When completed click ESC. You can select either a rectangular block or irregular block and draw the points yourself.

IrriExpress Irrigation Software

Add a Valve to the block by selecting Nodes then Valve from the Irrigation Menu.

The Valve menu will be displayed. Select a valve.

IrriExpress Irrigation Software

Place the valve close to your block. If you know where exactly the valve must be, place it there.

The valve can always be moved to a new position at a later stage.

IrriExpress Irrigation Software

From the Block menu, specify if the block will be a solid set or drip.


IrriExpress Irrigation Software

The Solid Set is normally used when each sprinkler is represented by an emitter node.

The Drip option is used when the emitters are embedded into the pipe.

This part of the example continues with the Solid Set type.

Select your Emitter type by first choosing the Series, then the Model, Nozzle and finally the design pressure that the block will use to do the hydraulics and size the pipes.

IrriExpress Irrigation Software

Select your Lateral

Note that in the bottom left, the application type is fixed as Laterals since the layout will be done with lateral pipes.

IrriExpress Irrigation Software

In the Place Layout menu select the Row and Emitter Spacing.

Please note, there is a limit on the number of emitters that Express can accommodate in a block.

IrriExpress Irrigation Software

A ghost image of the defined layout will be shown inside the block.


IrriExpress Irrigation Software

To turn your layout counterclockwise or clockwise in 1 degree intervals press the Page Up or Page Down buttons.

To rotate the layout by 45 degrees, use CTRL page up or down.

Once satisfied with your layout, click on the screen to place the layout.

The laterals must now be connected to the valve and it can manually be done by using the regular add pipe option. To do it automatically, use the block menu and select Place.

IrriExpress Irrigation Software

From the menu that comes up, select the type of manifold you want and click OK.

IrriExpress Irrigation Software


Notice the application type is now fixed as manifolds.

The manifold will now be connected to your emitters and valve.

IrriExpress Irrigation Software

Hydraulics can be run for your block by going to the Irrigation menu and clicking Run.

IrriExpress Irrigation Software

See Run Hydraulics for more information.

IrriExpress Add a Node - Help Tutorial

Posted on February 02, 2016 by Susanna Whitford

Add a Node

Click on Node from the Irrigation menu to add a new node. Select the type of Node you want to add (Pump, Valves, Emitters, etc). Each Series has multiple Models, choose the one needed and click OK.

IrriExpress Irrigation Software

After placing the node on your workspace, hit ESC to return to the Node menu.

Click Cancel to close the node menu.

IrriExpress Irrigation Software


Types of Nodes

Pumps: is a device that moves fluids by mechanical action. This is also the source node of the mainline.


 Valves: allow water to exit the system. In the mainline, valves are used to manage the flow to blocks and pivots.

The irrigation blocks will each have a valve that acts as source node. The block valve is also the connection between the inlet to the block and the mainline.

Emitters: can either be sprinklers in a solid set block or drippers in a dripline block. It is used to transfer water from a pipe or tube to the area that is to be irrigated. Typical emitter flow rates are from 0.16 to 4.0 U.S. gallons per hour (0.6 to 16 L/h). In many emitters, flow will vary with pressure, while some emitters are pressure compensating.

Fittings: a device that makes a connection between pipes.

Regulators: a device that maintains a designated characteristic, for example when the pressure in the system needs to be reduced to a certain value.

Boosters: a device that increases the water pressure of water that is already moving.

Nodes are defined in the nodes database.

IrriExpress Adding a Pipe - Help Tutorial

Posted on February 02, 2016 by Susanna Whitford

Add a Pipe


To add a pipe to your project, first add a node.

Project with nodes already established:

After the nodes have been added, click on Pipe on the Irrigation menu.

IrriExpress Irrigation Software

Select Group Code and Group Name, types of pipes will update. Select the type of pipe you need and hit OK.

Notice in the bottom left the Application type.
When working in the mainline, the setting will be fixed to 'mainline'

When adding pipes in a block it is important to select whether the pipe acts as the manifold or lateral.
Manifolds and laterals are handled separately when their pipes are resized for optimum flow and pressures.

IrriExpress Irrigation Software

IrriExpress Irrigation Software

When adding pipes, the boxes at the top of the screen indicates if you are snapping to existing nodes or if new nodes will be created at the indicated endpoint of the pipe.

IrriExpress Irrigation Software

Click on New Node to add a new node for the pipe to connect to. Then select the type of node you want to add to your project.

Irrigation Menu in IrriExpress


IrriExpress Irrigation Software

IrriExpress Irrigation SoftwarePipe:
The irrigation system consists of nodes and pipes. Use this option to add individual pipes to either the mainline or the selected irrigation block.

Pipes can either be added between existing nodes or by using the CTRL key, nodes can be generated as the pipe is being added.

IrriExpress Irrigation SoftwareNode:
Nodes in the irrigation system are points to facilitate the pipe connections, to specify the mainline pump or block valve or to place emitters, regulators or booster pumps.

Nodes can be added individually or generated when new pipes area added.

IrriExpress Irrigation SoftwareBlock:
The base elements in the irrigation system are the mainline and individual blocks. The mainline is automatically defined but irrigation blocks which have their own control valve must be defined by the user. Once a block is defined, the layout of a solid set or driplines can be done.

Available on IrriExpress Blocks and IrriExpress Full.

IrriExpress Irrigation SoftwarePivot:
Pivots are entities on their own with their water supplied by the mainline.
When a pivot is added and the spans and starting pressure specified, the program calculates the flow needed by the pivot and when pipes are added between the pump and pivot, the mainline hydraulics will be calculated.

Available on IrriExpress Pivots and IrriExpress Full.

IrriExpress Irrigation SoftwareLaterals moves can be created by IrriExpress from the Irrigation menu. Laterals' length and width are decided when creating the object on your workspace.

Available on IrriExpress Pivots and IrriExpress Full.


IrriExpress Irrigation SoftwareQuickly cut a series of pipes and place emitters at each intersection.


IrriExpress Irrigation SoftwareRun:
Run Hydraulics on your project to determine the pump pressure of the mainline and the valve pressures of the blocks. Here you will also optimize pipe sizes and view the hydraulic detail of your irrigation system.
