HI All whilst draining caravan last weekend I noticed underneath the van was a length of black pipe with a red bung on the end, I left this and didnt open the bung as i wasnt sure what it was for . I unscrewed the drain down on the carver water heater and that drained the hot and cold water system. What does this red bung do???? Is it best to leave it alone as it felt quite loose???
Your help on this would be much appreciated
