We have no found out what is causing the leak - though the original owner did send us a message even though we had never met him telling us where he suspected it might be! It is not a huge priority at the moment as (spoiler) in a later episode we get new drinking water jugs to get us by until the water tanks can be replaced. At the moment budget is the issue but thanks to our Patrons supporting the journey we hope to be able to afford one before the Pacific crossing!!
