Thanks to everyone for your ideas on our leak. We have checked under all the cabinets and drawers on the curb side of the coach. Did find a leak under the sink last night - repair guy coming on Monday. Hope that is it! P trap is dry. The overflow drain from the refrigerator defrost has been rerouted so that it now drains outside rather than in the little cup provided but haven't seen any water on the ground outside.
We are hooked to city water so water pump not coming on. The water has been mostly in the hall between the washer/dryer and the bathroom. Just had some on the top of the floor in the kitchen, thus found the leak under the sink. I will tell the repair guy all of your ideas. Is this something that he should be able to fix? We were told if we have to take the floor up we may have to go to the factory -- really hoping its not that serious!
