I bought a 2007 four winds hurricane and when I went to dump the tanks I found there is a duplicate dump valve in the gray line just behind the rear wheels on the right side. There are the normal black and gray valves at the dump site on the left side.
Can anyone explain why its set up this way? Pretty sure its a factory setup.

I am kind of confused by what you say. On most newer RV'S there is a kitchen gray tank and a bathroom gray tank. Then there is one black tank.

Does this help answer your question?

I guess I am going to have to crawl under and see if there are seperate gray water tanks. Thanks for any input.

One way to tell is where your dump at you will have 2 smaller(I believe 1 inch) running into a 3 inch exit pipe.

1 inch pipe is for gallery another one is for bathroom and the 3 inch is for sewer(black).

Also if you check your monitor panel it should have the option to view the tank level of three tanks(grey + grey + black). This is another clue without going under the MH.

I just got off the phone with thor ind. tech support concerning a matter other than waste dumping. He said the second valve is placed on the passenger side because the holding tank is there and code requirements demand a valve be placed within 30 inches of a tank. Now it all makes sense to me.
thanks to everyone who read and replied.
Now we all know why.

Code? What code?

I have the same setup. The black tank is on the right side resulting in a long pipe over to the dump side. The extra valve keeps the "stuff" from collecting in the pipe which could be a problem in cold weather. Frozen poop in a pipe is not good. Extra valve keeps all the stuff in the tank where it can be heated if needed.

I open the dump side valve first then the right side valve.

Portions of the regular plumbing, fire, gas and electrical codes apply to all RVs. The RVIA oversees the RV construction codes and supplies those few portions that are specific to RVs rather than residential.

This confuses me. Cause with my RV I have 3 tanks(grey,grey,black) All tanks are mounted ahead of the axles(I assume since levers are a head of axles) and I have a 30 foot RV. How could it be that it has to be 30 inches from the opening? I see if the one tank is located in the back of the RV, but mine are right next to each other?
