Is it possible that when I turn on my hot water heater that it would provoke a leak in the tank? I have a 2008 HR Neptune. I shut off all of the water to the coach, turned on the water pump, no app...
Open up outside access panel and see if you see relief valve or anything else that is wet - then gain access to the inside portion of the tank (often under a bench seat) and see if you can identify where it's leaking (may just need to tighten something) .. if that doesn't work then you have to follow the hot water lines until you find where the leak is. If you have outside shower -- make sure you check that as well.
