So...separate topic to E-control! On our spin today we stopped to get coffee and I noticed safety/drain valve was doing its stuff i.e. dumping in the carpark. I pulled up knob as per manual etc. This is the second time this has happened in as many days and I suspect it starts when the vehicle is parked. I've been monitoring and checking temp etc when she's parked at home and all was intact. So perhaps this explains the clothes peg and if so does this mean the unit is faulty? When I considered the matter I thought there must be no way of checking if I'm leaking while driving but then the light bulb went on...of course I can check water level before and after(clever again!) So my Qs are...1) does the clothes peg mean unit is faulty, needing maintenance or repair 2) What is involved in this and who would do it? I assume if I continue to monitor the weather and the water levels I could manage it as is but it would be nice to have it working as it should too. Filling water tank and priming might become a bit of a chore! Thanks in advance to anyone who shares/suggests/sympathises in any way!
