Welcome to the forum its a great place to get your questions answered. there are no plumbing schematics for these rigs. Make sure when you hookup to city water you have a pressure reducer installed it may be that a connection is leaking because of to much pressure. I would pull the corpolast (under belling covering) and dry things out while looking for the problem. you may need to pull some panels inside to trace the lines good luck.
