Separate Grey and Black Water Drains!

My Outback has 3 valves but 2 outlets that are about 6 feet apart too.

One is black and grey (shower/sink and toilet). The other is grey (kitchen galley).

When camping with full hook-up sites, I use a Y in my hoses. When dumping at the dump station, I dump black and back-flush from grey to my black, then dump again. Then switch hose to the galley outlet.

Solution to your problem is to use a Y when camping, and use a longer hose (like 20 footer) so you dump the black first. Unhook the hose and walk it to the grey second. This way you don't have to move the camper.

It would be no different than the way I currently do it, just a few feet farther. I use a 15 foot hose for dumping at the dump station.

We may start to see more of this with the units getting larger and plumbing fixtures located all over the place. Only have so much distance to slope the underbelly pipes.

I have a rear kitchen and the bath is in the middle of the unit, same set up with the 2 drains which are about 12 feet apart on mine. I never have a problem dumping them, I just dump the kitchen first and then the black and grey for the bath. I don't leave my hose hooked to the takeoff as I prefer to dump and then put things away again instead of leaving it lay on the ground.

In most cases where I've seen separate dump points it's because there is 3 tanks. One dump has the grey and primary black tank, and the other a secondary grey tank is this the possibility?

My Springdale has separate drains. They are a little closer together than yours - around 6 feet apart. It's a dumb design, but just an annoyance to me. I'll be sure to look at the next rig closer before we buy it to avoid dual drains.

You can buy a "Y" connector and run 2 hoses to one dump.

Some run new plumbing to join the two.

I also had a Gulf Stream like that. I did not like the set up as I had to dump one then drive forward to drain the other two as it had 3 holding tanks. I sold it after one year of putting up with it
