Apex LD-1 Leak Detection Probe for Use Under Carpet

The LD-1 is a low profile leak detection probe that is compatible with the Neptune FMM module only. The low profile design makes it perfect for placing it under carpet or in tight spaces that the full size LD-2 wont fit. If you do not have carpeting or space requirements we suggest using the LD-2 Leak Detector Probe.
 
Note: The LD-1 will only work with the FMM and cannot be used with the ALD module.
