Line Leak Detector Testing
Functionality testing for mechanical and electronic line leak detectors.
Manufacturer-certified · Testing UST & AST systems since 1997 · Serving 13 states and expanding
PTTI tests mechanical and electronic line leak detectors to verify operation under the applicable test procedure and regulatory requirements.
Testing Method
PTTI simulates a leak equivalent to 3 gallons per hour at 10 psi line pressure to verify the detector’s response under the applicable test procedure. PTTI documents the result.
PTTI uses calibrated leak-detector test equipment and follows the applicable PEI RP1200 procedure.
- Equipment
- Estabrook Leak Detector Tester and its calibrated test apparatus.
- Frequency
- Annual operability testing applies to covered automatic line leak detectors; the applicable requirements depend on the system and jurisdiction.
- Deliverable
- A record of the detector tested, procedure used, observed response, and result.
Common Line Leak Detector Failure Modes
-
1
Check Valve Malfunction
-

-
3
Corrosion or Mechanical Wear
Leak Detector Testing, frequently asked.
How often does a line leak detector need to be tested?
Applicable automatic line leak detectors require annual operability testing. State requirements also apply.
What is the difference between mechanical and electronic leak detectors?
Mechanical detectors typically restrict product flow. Electronic detectors can activate an alarm or shut down the pump, depending on the system. PTTI tests the installed detector under the applicable procedure.
What happens if my leak detector fails testing?
PTTI documents the result and identifies the cause, commonly a check valve malfunction, sensitivity drift, or worn internals. PTTI prepares the records, and the operator handles any state filing.
