So we bought a "Used" new to us Georgetown 351DS Bunk model and am wondering how to drain the Fresh Water. In my last RV it had a Handle just like the Black and Gray tanks that you pull and it would just dump it all. You could pull it and drive home and it would be empty by the time you get home. On this particular Motorhome all I see is a low point drain. When I open it a tiny bit of water will trickle out and then stop. Our fresh tank is full so I know it can't be this. Unless you have to run the pump in conjuction with the low point drain being open. If you do that water sprays out. Just not sure if this is the way to do it or not? I scooted around underneath on a creeper and couldn't find any other drains so I sure it has something to do with the low point drain. Just confused cause our last one you didn't have to run the water pump to drain it. I don't want to mess something up like if the pump is on and no water is coming out do I have to shut it off immediately so I don't harm the pump? Any help appreciated..

All of my valves are in the wet bay. Fresh water drain, low point hot, and low point cold.

On my rig, I open the low point drain then open the fresh water fill valve. Tank then drains slowly through the low point drain.

Open both the cold water drain and fresh water holding tank fill valves. If I don't open the fill valve, cept for a few slow drops nothing really happens. Interesting how long it takes to drain a hundred gallon holding tank! When I do drain the tank, I feel as though I should be watering a plant or something. ... :)Pops

Maybe I should take a few photo's of my Wet compartment where the Fresh fill and city water hookups are along with my Gray and Black dump valves. On the opposite side of the coach is my low point drain. There is no valve to turn on to fill fresh water just a garden hose inlet that I saw..

I'd unscrew the cap to see if that would allow the tank to drain. I'm not good a physics or science, but IMO it's Sorta like a straw. Hold one end, and the straw holds the water. Release one end and the fluid is no longer in the straw.That's the reason (in my Motor Home) I have to open the fill valve to allow the tank to drain. The fill valve in my motor home directs the flow of water entering the Motor Home. Closed it allows the city water connection to flow through the Motor Home, open and it fills the holding tank.Unlike my previous Motor Home. I either directly connected / screw the water hose to the city water supply inlet. To fill the tank, I unscrewed the cap to the gravity feed inlet. With this set up I could fill the holding tank via a water hose, or five gallon / gallon jug.Anonymous

"The water holding tank has a relief valve at the end of the tank and this drains through a pipe through the floor at out the bottom."

Ditto for my Rambler

Suggest you try to obtain Owner and Service Manuals on-line, or from a local dealer or the Manufacturer.
Used RV parts suppliers may have them in their inventory.

X2! Got stuck behind a toyhauler draining his tank "on the go" coming home yesterday. Why not just drain it when you get home? Oh, I see....you don't want water everywhere. Yeah, neither do we.

Mowermech was right on. Mine was in the same compartment as the Propane. I have a 1" plastic pipe that is the low point drain and right next to it is another 1" plastic pipe not labeled. I undid the screw cap on this pipe and low and behold it started draining. I'm pretty sure that was what it is for. Thanks for all your help..

Glad you got it sorted out! ...

On our '02 GT325, there's a valve on a line from the bottom of the potable tank with a tube that runs outside under the back bumper. Open the valve, and the tank drains out. No need to give it air to refill that tank and break a vacuum.

Until I opened up the screwed-shut cupboard doors under the bedroom wardrobes, I didn't find that valve.

Our valve is in the same location under the wardrobe, but in our MH there is one door secured and the second door opens to provide access to the valve and the water pump. I do the winterizing from this point as I use the water pump to circulate the antifreeze throughout the lines.

in reference to driving down the road with drain valve open, a crazy Calif Vehicle Code section came to mind. The 2 things a vehicle can "drop" on a highway are water and chicken feathers. look it up if you want.

In CA you can dump fresh water or chicken feathers leagally. Don't laugh it is the law.
