Valve notation symbols do not show the flow for drip tubing zones.
The valve notation symbol command is not able to calculate the flow for drip tubing zones. When the command is enacted, the program looks on the design screen and gathers all of the sprinklers. It then combines the flow for sprinklers assigned to the same zone number. The command does not gather all of the drip tubing and attached lateral line and trace a path back to the valve to see which tubing is attached to what valve.
You have to manually adjust the text in the valve notation to indicate the flow of a drip zone. To manually adjust the text in the valve notation symbol:- Click on the Tools menu and then Edit Block Attributes.
- Select the valve notation symbol on the screen.
- In the Attribute Editor box, select an attribute to change.
- Enter the correct value and click on the OK button.
When running the hydraulic calculations or mainline pipe sizing, the program does trace the lateral pipe touching drip tubing back to the control valve and calculates the flow of the tubing. It then uses the flow to determine the pressure loss through the control valve back to the water source. It does not calculate a pressure loss within the drip zone itself.
