On my 2015 Greyhawk 31DS there appears to be three overflow tubes from my freshwater tank. I would like to know if it is safe to plug two of these and put a shut off valve on the other. I am tired of loosing 1/3 of a tank of water while driving. Thanks for any info help with this.

The only concern I see by capping a few off is during city fill. Using pressurized City fill (versus gravity fill) might put too much pressure on a single vent line. I doubt a single line can handle the back pressure when the tank hits max fill. This is why I believe they put in 3 hoses. 3 hoses would allow overflow from city pressure.
Last thing you'd want is to over pressure the water tank and possibly damage valves, tank or fittings..

I have not had any issues while filling the tank at all and I generally shut off the water when it starts to come out the over flow pressure at my home is about 60 psi You could add in a pressure reducing valve when filling if that was a concern
