2 drain valves under fresh tank
Good morning y'all. Haven't had a chance to fill our fresh tank yet. I can see the white plastic drain valve mounted to a bracket under the trailer, but there's also a pex tube hanging down from the center of the belly near the spare tire with a chrome valve on the end of it. Is this the fresh water overflow? If it is, I assume the valve can be closed to prevent the siphoning while driving I've read about. The low point drains are near the basement storage.
