Problem - Failure to sense 3 GPH @ 10psi leak during certification test
On-Site Information: Document test equipment utilized including model numbers and calibration records.
Reference Documents: This procedure references the following manuals 042-106-1 and C051-272.
Safety Precautions: Review The Red Jacket FXV Leak Detectors Installation Manual (042-106-1) for safety precautions,
warnings, and detailed procedures.
Troubleshooting Steps:
1. Verify that all air has been purged from the system.
2. Confirm installation of test setup is correct per manufacturers recommendations. Validate that the pump pressure and
orifice size correlate to the 3 GPH leak rate at 10 psi. Please document for tech support if needed.
3. Note the pump model and horsepower as well as fuel being used for additional background.
4. Confirm leak detector is in leak sensing mode per C051-272. Review to assure detector is in leak sensing mode at 11-16
psi line downstream prior to opening up.
5. Confirm actual induced leak is at least 3 GPH equivalent. Calculate as necessary.
6. Review FX leak detector tests per C051-272. Compare actual test procedure to approved Veeder-Root test procedure.
7. Replace unit if minimum leak detected is greater than 3 GPH or if it exceeds your company’s specifications.
8. Call Veeder-Root tech support at 800-323-1799 if new unit does not resolve concerns.
