De-winterized and discovered a small leak yesterday. Pulled the coroplast, and the leak appears to be coming from where the KIB sensors are installed (see pic). Has anyone dealt with this before, and if so, do you know the recommended approach for fixing it? Have a call into NuCamp, but who knows if they will get back today. As Murphy would have it, planning on leaving tomorrow. I know I can 'wing' a fix, but would like to do it right so that I don't have to repeat anytime soon.

Thanks for any insight!

    Any likelihood it's as simple as tightening it? Seems like an odd thing to loosen, but I suppose the rubber material could b e failing over time, in which case I assume I'd need a new sensor(s)?

    I would check to see if there is any play in the nut.  Looks like there is a washer that may need replacement, too.  Can you tell if there is any sealant under the washer?

    Cannot tell, but looking at install videos I don't think there should be.

    Are the sensors on top of the tank?

    You may have better luck sending a photo and question to tech@nucamprv.com.

    Sensors are on the side, where the nuts and wires are in the pic. Have talked to Creede about it, he's never seen this before. As it turns out, it's because there is actually a pinhole leak at the very top edge of the tank, in the concave part of the 90° angle (image below). After tightening the sensor nuts, I refilled the tank fully, at which point the leak was obvious, as it was spurting out from a single point. I guess the water had leaked enough overnight that this morning it appeared that the water was coming from the sensor. Leak circled in yellow below.

    I guess I'll look into some sort of Plumbers Goop (that I've read about here) to seal the hole. Very strange place to develop a leak after 2+ years of owning it.

    I wonder if something kicked up from the road through that gap in the frame?

    Yet yet another reason to cover those slots.

    While I doubt this was caused by driving with a full water tank, I’ve been curious if there are negative impacts (aside from gas mileage) of driving with a full tank on mounts and the tank itself getting stressed?
