I have a truma 6E fitted to my 2008 Adria. On a rally at the weekend I noticed my Sureflow pump was switching on momentarily every so often. I also noticed a steady drip of water coming from underneath the motorhome, which looked to be dripping through from the floor above. On looking at it today I noticed water coming out from underneath of the truma - not a lot but a steady amount seems to be coming out. And the insulation cover on the underside seems very spongy. Not sure if this is being soaked up from leak elsewhere or coming from the unit itself. My trouble is we are going to Lincoln on Thursday! Does this sound terminal for the unit or is there something I can check or adjust relatively easily please?
