I was readying the moho (2018 Adria Coral 670 SL) for heading off for Christmas and after filling with water and turning on the heating I heard the water pump firing up several times across about 15mins. Thought this strange and left it for a while thinking there may just be a drop in pressure as it had been drained for quite a while. Returned about 2 hours later and it was doing the same. Checked all the usual places for a leak and lo and behold we have the dodgy Adria fittings leaking. First time in this joint but had several throughout the system since I bought it in Sept 21. Anyway tried the usual of pushing the pipe fully into the joint and pulling it back slightly as this has worked previously. Whilst doing this I noticed this strange device, which looks like some sort of a sensor, lying on its side on the floor behind the pipes. Has anyone got any idea what it is and how it should be situated and in what position?
