I can't tell you how many times we had to deal with water issues, sinks overflowing, toilet pedal sticking and water running over the top, hot water heater rupturing and flooding the motorhome with water. We have gotten very good at tilting the motorhome with the levelers to let the water run out the side however it can find a way. It drys. Use any or all of the suggestions about but go camping. Can't deal with the dealer or manufacture over the weekend but do document all of your telephone calls with time, date and who you spoke with. Also send a certified letter to the customer service of both the dealer and the manufacture. If possible get it to the manufacture for repair. The dealers don't get paid by the hour for warranty work so they look for the quick fix. Problems are just part of the experience and soon you will writing of yours and possible solutions. Call the campground tell them what happened and that you might be a day late. They may give you credit or not but GO!!!
