Spill Container Inspection Best Practices

Franklin Fueling Systems’ spill containers should be inspected and receive any maintenance on both a monthly and yearly basis as explained below.

IMPORTANT: To help avoid damage to the Interstitial Integrity Monitor, do not attempt to remove it if the temperature is below freezing (32° F, 0° C).

Recommendations for 30-day inspection and maintenance

IMPORTANT: Make sure you follow all local, state, and federal regulations. For additional information, see the Defender Series™ Double Walled Spill Container manual (part #F-9028).

  1. If liquid is in the spill container or the interstitial space, dispose of it. To remove the liquid, use your preferred method (a pump or rags, for example).
  2. If liquid (including hydrocarbons) has collected, check the o-ring on the Interstitial Integrity Monitor entry fitting. If it is damaged, replace it with part #400333132. If it is not damaged, proceed to the next step.
  3. Perform the Vacuum Interstitial Integrity test. (Use a 2” socket to remove the Interstitial Integrity Monitor.) If the test fails, replace the spill container.
  4. Once you have removed the liquid, and have performed a vacuum test, re-install the Interstitial Integrity Monitor in the inspection port, and torque by hand to 25 lbf • in.
    • Make sure the o-ring is lubricated with motor oil or silicone grease. Also make sure it and the inner diameter sealing surface of the inspection port are clean.
    • If the o-ring is damaged, replace it with part #400333132.

NOTE: If the unit includes an electronic sensor, do not remove it.

Recommendations for yearly inspection and maintenance

IMPORTANT: Make sure you follow all local, state, and federal regulations.

  1. If liquid is in the spill container or the interstitial space, dispose of it. To remove the liquid, use your preferred method (a pump or rags, for example).
  2. If liquid (including hydrocarbons) has collected, check the o-ring on the Interstitial Integrity Monitor entry fitting. (If it is damaged, replace it with part #400333132.) If it is not damaged, proceed to the next step.
  3. If interstitial monitoring equipment is installed with the Interstitial Integrity Monitor, test both the float and the indicator mechanism. To remove the Interstitial Integrity Monitor/port pipe assembly, use a 2” socket to unscrew it from the tank adapter. Manually move the float up and down, and verify that the float moves freely and the indicator arrow rotates.
  4. Make sure the o-ring on the Interstitial Integrity Monitor entry fitting is lubricated with motor oil or silicone grease. Also make sure it and the inner diameter sealing surface of the inspection port are clean.
  5. Use a 2” socket to re-install the Interstitial Integrity Monitor in the inspection port. Torque by hand to 25 lbf • in.
