If you can't find a leak, and I'll bet you can't if pump comes on that little, there is another spot. There is a valve between the pump and the fresh water tank. That valve will sometimes gradually let pressure off by letting water back into fresh water tank. So by all means look for a leak. If you don't find one, just turn off the pump when unneeded. That is what we do, and it is a good practice anyway. If you always leave the pump on, someday when you are not in the TT a leak will develolp and you will return to a real mess.
