Hi guys, We lived in our caravan for 2 years and now only using on occasion. I have been running water through all pipes at least once a fortnight. Took the van away this weekend and the shower hose has gone berserk. Water coming out from where the nut is everywhere. We tightened this nut but still coming out. Any ideas before we bite the bullet and get a plumber in. We no longer live near a caravan place so that no longer an option.
