Grey Tank Operation 101

Now that I have a couple weeks under my belt. Could almost say a seasoned RV'er now. I have a question how those with more experience handle the grey water tanks, specifically the Galley Tank.

There is one tank that seems to collect water from the shower and the kitchen. This one I have to drain at minimum every two days. The other tank has yet to see 1/3. Not drained in two weeks. (I do use the faucet in the bathroom and bedroom)

If it is above freezing, can I just leave the valve open on the galley tank, or will I get sewer gas coming up from the sewer line doing that?

Why would you design a system and put the most heavily water use drains into the same small tank? Kitchen and Shower

Why put two little sinks into the same tank?

Scott,

Yup, the only thing that feeds the grey tank are the 2 bath sinks and the washer. I asked the same question and apparently the drain lines had to be run that way. Disappointing that the shower doesn't drain into the gray too.

Yes, you can leave the galley tank open. If you're concerned about sewer gas, drop a short section of your sewer hose in the form of a large p-trap, making enough of a drop to fill with water.

Many of us have asked the same question......why most everything going into the one gray tank? You can possibly resolve the dilemma as follows: Purchase an external tank valve that connects to the end of your existing sewer drain on your Redwood. Close the external valve that you just connected and then open both of the gray tank valves in the convenience center. This should allow you total capacity of both tanks for any drain you use. When it is time to drain the tanks, close both gray water tank valves in the convenience center, open the external valve and drain the water that is in the line. Then open the black tank and drain it, then open each of the gray tank valves(one at a time) and drain them. Then start the process all over again. This seems to work for most of the Redwoods.

Didn't think of the washer/dryer. Don't have one, yet. Thanks, for the the p-trap idea, that makes sense.

The experts plumbed the washer drain into the tank with the bathroom sink. Great if you have a clothes washer but I believe most folks using a washing machine are in an RV park with electricity and sewer connection. I considered replumbing our tanks but it is an impossible job to get adequate access to the drain pipes after the coach is assembled.

http://www.amazon.com/Valterra-T58-T...rv+sewer+valveI hope I do this right: This worked for me and I was able to take advantage of the 90 gallons of gray water storage.

We are full timing and leave both grey valves open all the time. I only close them the day before dumping the black so I can rinse the hose out. I get no smell in the trailer. If below freezing you can let the tap trickle water to keep the hose from freezing

I use this valve too, makes it easier to flush and rinse the black tank. I tried to leave the two tanks open to equalize using the external valve. I had a large leak in doing so. It turns out, there was a leak on the back side of the galley tank valve. Once repaired, I tried equalizing the tanks. Looks like this worked for me too, but I'd like to try it a few times before I declare success.

All the fixtures that drain into the gray tanks have p-traps and the valves can remain open without worry of ordor.

I am not sure I totally understand what is being described by using this other valterra T58 valve. I do know that on my GK I cannot leave both grey valves open. It does allow sewer gasses to come back into coach. I have never had that problem on my former coach. A carriage-carrilite. But neither did I have a lot of other strange problems that I have experienced with the RW either.
