LD-1 Low Profile Leak Detection Probe

- +

Low Profile for placing under carpet or in tight spaces.

Be notified if there is ever a leak before it turns into a disaster. Connecting the LD-1 Leak Detector to the FMM module will allow your Apex Controller to notify you if water ever touches the sensor. There are many applications for leak detectors from water on floor warnings, skimmer cup overflows and much more. 

  • Compatible with FMM
  • Low Profile

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 requirments 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.

Product Questions

Hi! Can i use this detector with the same ffm module of my ATK? I would like to add an optical water sensor as well. Does it work? Because the ffm module has two more free plugs that I would like to use for these two devices

Thanks for the question! Yes the LD-1 can be used on the same FMM as your ATK without issue. Let us know if we can help with anything else!

I already have an FMM Module and obviously an Apex. Do I need any other pieces/parts to make this work with the system? Thanks.

No, that is all you need.

How long is the cable for this leak detection probe?
Question by: William Percy on Jun 27, 2019, 11:48 AM
Great question! Tracked one down here and measured it myself. The cable is 8 feet long :)

Do I have to set up anything for my low profile leak detector onto my apex?
Question by: Ruben Doering on Dec 11, 2018, 2:00 PM
Along with the Leak Detection Sensors you will also need the LDK module. Once connected to the Apex, you can easily program them using the "Tasks" function for adding a LDK. :)
