Prior to Troubleshooting
If the line leak system is installed into a FE Petro STP, be sure it
contains a check valve which is designed to support Veeder-
Root line leak applications. The line leak system will not work if
the correct valve is not in place.
If the line leak system is installed into a Red Jacket STP, the
functional element must be disabled and the relief venturi into the
siphon pipe must be free from blockage.
IMPORTANT
When measuring the pressure in the line for comparison with
pressure transducer readings, always install the pressure gauge
DOWNSTREAM of the Check Valve (such as at the emergency
shut-off valve). DO NOT measure pressure at the STP.
