Hydrants Setup: Preferences
Purpose Statement
This article outlines how administrators can configure hydrant display preferences within the Hydrant Module. These settings allow customization of hydrant outline and fill colors to improve visual clarity and support operational decision-making based on flow data.
Background Information
The Hydrant Module in First Due enables agencies to manage hydrant data, including location, flow testing, and maintenance records. The Hydrant Setup Preferences allow administrators to define how hydrants appear on the map, enhancing usability for field personnel and supervisors. Color-coding based on flow rates supports NFPA 291 compliance and helps identify hydrant capabilities at a glance.
Required Permissions
Only users with Admin or Configuration permissions can
create, edit, or delete Hydrant Zones. These permissions can be managed under
Admin > Roles & Permissions > Hydrant Module.
- Hydrant Setup--Allows for access and editing of the Hydrant
Setup Area

Step-by-Step Guide
- Navigate to the Hydrants Module, then select the Hydrant Setup and finally select Preferences.
- Set Hydrant Outline Color
- White Outline
- Black Outline
- Configure Hydrants Color by selecting one of the following hydrant colors:
- Hydrant Base Color--Allows manual color selection for each hydrant and is not based on flow data.
- Calculated Flow Rate-- Automatically updates hydrant color based on theoretical flow rate which is derived from flow test data entered in First Due. (Uses NFPA 291 color standards)
- Hydrant Flow Rate--Automatically updates hydrant color based on actual flow rate and reflects real-world flow test results. (Also follows NFPA 291 color standards)
Best Practices
- Use Calculated Flow Rate for planning and
theoretical analysis
- Use Hydrant Flow Rate for operational
readiness and field accuracy
- Avoid manual base color unless customization
is required for non-flow reasons
- Ensure flow tests are regularly updated to
maintain accurate color coding
Troubleshooting & FAQs
Q: Why isn’t the hydrant color updating after a flow test?
A: Ensure the flow test was completed and saved correctly.
Check that the hydrant is set to use either Calculated or Flow Rate coloring.
Q: Can I override the automatic color?
A: Yes, by selecting Hydrant Base Color, you can manually
assign colors.
Q: What if my agency uses different flow thresholds?
A: NFPA 291 is the default standard. Custom thresholds may
require manual color assignment or system customization.
