To repair a leak in a tub of polypropylene washing machine I have the simple and free solution.
Simply cut a small piece of polypropylene from the outer tub that is not used or find on another to the dump and melt with a soldering iron tin or zinc.
First make a big bead on the hole then spread with the flat iron the bump and all around the hole to assemble in one piece... And that's it.
Good nick to the manufacturer who thought to throw disposable! Macgiver is here.Suggest a tip for this theme
