When I went out last night to work on the bunk beds I found a small puddle of water by the fridge.I cleaned it up and had bad thoughts about a possible leak through the fridge access door or the outside stove. I'd filled the tanks last week to check for leaks and to test to make sure the tanks didn't block off the furnace. I opened a cabinet and found one of my baking pans full of water. Seems the leak is coming from the sink drain. Its a weak design to let the pipe run unsupported, and of course the leak found the weak spot in the coupler. I've got to call the dealer to run in it, I could probably fix it myself but I think I'm going to ask them to brace the pipe as well since I can see the bouncing around causing this again. Not a big issue, glad I found it out now though.
