When we camp and are not connected to sewer lines, such as some Nascar campgrounds, we can fill our bathroom shower tank before our Kitchen, galley tank.

To save the cost of getting the trailer pumped out I added a valve on the trailer at the outlet just before the point the "stinky slinky" gets connected.
I now can open both the grey water and the galley water valves keeping that extra valve closed.
Now both Grey and Galley tanks act as a single tank.

I think the extra valve was $30

Cheers

Could you post a photo of this? I want to do this on mine and I think I know where you put the valve but before I do it a photo would really help. Understand if its not possible.

Or you can do like the rest of us and experiment with usage while enjoying a weekend (or longer) of camping. The drains will gurgle long before the shower-pan starts to fill. .......... Travel safely, Hank

The grey tank for the shower will back up into the shower.. I know, last trip out I am outside by the fire and the wife is inside and I hear hollering..She is yelling dump the shower grey water ITS COMING BACK UP INTO THE SHOWER! We had 4 of us taking showers over 4 days. I get to camping and forget the little things. Fire was more important at the time to me. Also the kitchen grey water will over flow too. That has happened once when we camped last year for 10 days. with cooking and washing of dishes, it came back up and out the vent pipe fitting. What a mess that made.. about half of our towels were used to mop that up. The wife had to go and wash towesl so we could finish out the trip.
So my understanding is that what ever your total grey is is divided by each tank so if it says 76 gallons you have 2 identital 36 gallon tanks or what ever you numbers are.

I suspect he bought one of these valve assemblies that just twists on where you'd connect up your stinky slinky. The sewer hose would then connect to the other side of this.

Will do tonight,

I cut off the end of the sewer pie and glued on a new valve with the hose adapter.

I have seen the one from camping world but I wanted a more permanent solution

I'll post pictures tonight.

Cheers

Extra sewer valve, cut off the old sewer connection right behind where the coupling was glued on.
- a 3" coupling- valve fitting for the back side.Glued with ABS glue to 3" pipe
- a new 3" valve only
- a sewer hose twist on coupling-valve adapter
-4 bolts to hold it together
Picked up the parts from my local RV dealership

The tanks are seperate, If you fill up your galley tank, it will back up to your kitchen sink. If you fill up your bath gray tank, it willl back up to the shower. If your black tank fills, it will not flush from tollet. Both gray tanks should be the same size. If it is a big problem, enpty both tanks, close valves, fill the kitchen sink one gallon at a time. Then you should be able to figure out the size of each tank.
