You wouldn't see water. Just feel the carpet is wet, and/or smells musty. Just because it's doesn't look to be a leak somewhere, doesn't mean there isn't. Mine was seeping slowly through the draincock. Took me a while to find it as saw no signs it was leaking at all. Only way I discovered it is I was underneath looking right at it. Never would have seen otherwise. Sometimes hoses can seep as well, but only a bit here or there, leaving no real signs for you to see.
The beatings will continue until attitudes improve!
