Automobile Leak Testing System

For clients who have to leak test vehicles to ensure that there has been no water intrusion after manufacturing or modifications, we have developed a complete leak testing system. Custom engineered to fit your facility and testing protocols, our water intrusion / leak testing systems consist of containment pads, test arches, a water supply system and a fully automated filtration system designed to remove contaminants from the test water so that it can be re-used for a period of time prior to disposal or discharge to the sewer. Designed for commercial and industrial applications, all features of the system are manufactured to insure superior performance and minimal operating requirements.

The containment system consists of a water containment pad constructed of steel or heavy-duty PVC.

Sized to fit your facility and test vehicle, these pads feature entrance and exit ramps and drive over and/or pedestrian grating, if desired. Custom-sized water-proof canvas canopies, PVC curtains or Fiberglass walls are installed on the pad to minimize overspray.

The leak test system is built to fit into the containment system so there is no overflow. Depending on the client’s needs, the leak test system will include multiple side and overhead spray arches, vertical spray posts, and undercarriage spray bars, positioned to provide optimal coverage.  The spray test will last for a client-specified period of time and can be easily controlled by a driver with a remote start/stop key fob.

During the water intrusion / leak test, water is automatically pumped from the containment pad through an initial filter to remove any minor solids and contamination. From there, water is pumped into manifolded water management tanks.  The tanks provide enough water storage to permit proper water balancing during the testing period and the water recovery time. The tank system is equipped with level switches to protect the pumps and to automatically provide for fresh water make-up due to evaporation or drive-off losses. From these tanks, water is pumped back to the test arches, when needed.

In most leak test applications, the contaminants are minimal so this pumping and filtration cycle can last a considerable amount of time. When the water becomes too contaminated to re-use, however, the water can be pumped out or processed through additional filtration and discharged to the sewer.
