What action should be taken if foreign material is found during hydrant nozzle testing?

• A. Remove debris and re-test
• B. Ignore it and continue testing
• C. Increase test pressure
• D. Replace the nozzle

Answer: (A)

Foreign material can block flow and distort test readings, so the proper action is to remove the debris and re-test. Cleaning the nozzle ensures the hydrant delivers the expected flow and pressure without obstruction and prevents debris from causing downstream issues. Ignoring the debris won’t fix the measurement and could hide a blockage or damage. Increasing the test pressure won’t remove the obstruction and may create unsafe conditions or mislead results. Replacing the nozzle isn’t warranted unless the nozzle itself is damaged; clearing the debris and re-testing is the appropriate first step.
