Documenting Hydrant Flow Testing

Documenting Hydrant Flow Testing

Purpose

  1. To explain how to document Hydrant Flow Testing.

    We recommend reviewing NFPA 291 - Recommended Practice for Fire Flow Testing and Marking of Hydrants to familiarize yourself with flow testing guidelines.

Directions

  1. Navigate to Hydrants > Hydrant List.






  2. Locate the Hydrant you wish to test by using any of the search filters in the header section. Select the Search button.





    You can also find the Hydrant by scrolling through the hydrant list.  Underlined items in the in the table header row are hyperlinks that enable you to sort by ascending (select link once) or descending (select link a second time). 




  3. Select the "Start Flow Test" icon  in the Actions Column.






  4. In the Test Hydrant section enter the following information:
    1. (A) Measured Static Pressure - Enter the static PSI reading from your gauge.
    2. (B) Target Pressure Differential % - This is set by default to 25%.
    3. (C) Maximum Test Residual Pressure - This will calculate from the PSI reading entered in the Measured Static Pressure field.
    4. (D) Measured Test Residual Pressure - Enter the residual PSI reading from your gauge. (Per NFPA 291, the recommended minimum test residual pressure is 20 psi)






  5. If you are using the Test Hydrant as a Flow Hydrant, move the slider to the on position to reveal the data fields used to calculate the hydrant's flow.






  6. In the Outlet Size dropdown, select the diameter of the hydrant outlet.






  7. Enter the Coefficient of the hydrant using the chart below.  


    IMPORTANT: The data must have a 0 as a lead number. The entry can not begin with a decimal point (e.g., "0.9 is valid;  ".9" is not valid







    Coefficients are determined by the shape of the hydrant outlet and the friction loss determined by each version.

    Reference: NFPA 291




  8. Enter the Residual PSI from the discharge port. Hydrant flow will then be automatically calculated.






  9. If you do not reach your desired 25% drop in psi you can add a discharge.  Select the Add Discharge button and enter the information as explained in Step 8 above.









  10.  If you are not using the test hydrant as the flow hydrant and you are using one or more hydrants as the flow hydrant(s), ensure the Use as Flow Hydrant slider is in the off position and select Add another flow hydrant.






  11. Once you select the Add another flow hydrant button, a hydrant map will appear.
    1. (A) Your residual hydrant will be colored blue .  Any hydrant that can be used as the flow hydrant will be colored red 
    2. (B) Once you have chosen the flow hydrant click on the hydrant and it will switch from red to green .
    3. (C) Select the Save button and enter the data into the fields outlined in Step 8 above.












  12. Next, enter additional details of the testing in the panel on the left side of the screen.
    1. (A) Enter the date of the flow test.
    2. (B) Select personnel from your organization who conducted the test.
    3. (C) If applicable, select the vendor who conducted the test.  (This dropdown is populated from your Vendor List)
    4. (D) Enter any notes from the test into this area.
    5.  Select the Complete and Exit once the information has been entered.
