Pressurized Piping Leak Detection
How do you tell if you have an automatic line leak detector or a stand-alone sump sensor? |
| First, open the sump lid of your pressurized piping system. |
 |
|
| Second, locate the pump. It is usually red or blue and is between the top of the tank and the piping which leads to the dispenser. |
 |
|
Next, look for the line leak detector. Can you see a mechanical or electronic line leak detector?
The mechanical device is threaded into the pump head and has no wiring connections. They usually have a round or hexagonal top and should have a stamped brand name like Red Jacket, EBW, Vaporless, FE Petro or Veeder-Root. Newer models have copper bleed lines attached. |

| The electronic device is also threaded into the pump head. It is either wireless or hard-wired to the pump electrical system. Common brand names are Incon and Veeder-Root. |

| Oops. If you find no evidence of a line leak detector, your pump probably looks like this. This is an unsafe system and should be retrofitted with a mechanical or electronic line leak detector. |

| Sump Sensor. If you have double wall piping, you may find a a sump sensor like the two pictured here to the right. However, a sump sensor must be used in combination with a line leak detector. |
