Hello. A few days ago I cleaned the water tanks at our camper and the pumps tested everything works. Now a par days later and the toilets flushing does not make anything meher. I noticed when I removed the cassette a short (4-5cm) cable what was just lying there. Can it be that the in front of the owner has snuffed something short and jettisons where the cable is out so no function meher is? Fals yes you know what.
