How are you guys dealing with the second gray water dump position?

I did the walkthrough on my newly purchased Vibe Extreme Lite 268RKS today. It has a forward dump position where the gray and black water tanks come together to a single dump valve - fine. But it also has a separate gray tank for the kitchen which has its own dump position. This valve happens to be under the slide which is going to make it extremely cumbersome to get to when the slide it out.

What's the conventional wisdom here? Do you get a second dump tube and hook it up to the kitchen gray (before you put the slide out)? Do you just leave it lying connected on the valve end until you need to dump and then remove your other tube from the sewer pipe? Do you get a Y connector and feed them both to the sewer pipe? I see lots of options with various pros and cons to each and I'm wondering what other people do.

BTW, I really hate having this dilemma. I'm almost thinking of seeing if I could somehow run that gray water line forward to the other one so everything could some out of one valve. Anyone done that?

Thanks for any insight.

Both have been done- plumbing them together and having the hoses connect to a WYE before the campground's sewer connection. I do the latter due to concerns about enough drop between my two connections.

This shows how I handle mine:

I looked at plumbing mine together, but I have the axle to deal with. Couldn't go over it; didn't want to go under it. The valve for my kitchen gray tank is also under the big slide. I use a "Y" just before the sewer dump, with a hose coming from each valve on the trailer. On the gray tank under the slide, I leave the valve open, but add an extra twist-on valve from Amazon where that hose connects to the "Y" so I can dump that tank without having to crawl under the slide to reach the original valve. Fortunatelt, with only the kitchen sink feeding that gray tank, it doesn't have to be dumped nearly as often, but my set-up works just fine. Valterra T58 Twist-On Waste Valve: Automotive

Being lazier than everyone else, I plumbed the galley tank into the front and added another shutoff valve. Even tho' it does not completely drain the tank, it is sure easier than messing with another slinky and a wye and it was worth the $20 and about 4 hrs labor.

Very carefully with a 1-1/2" hole saw and then filed the elbow until it was a very snug fit and just glued it, did the same at the front. Hasn't leaked in 3 years. When we're in FL, I empty all the tanks about every 4-5 days.

The 282 rk Hemi is set up the same way, I put the galley hose on before extending the slide, then use a "Y" connector to join the forward tank hose to the galley hose at the connection with the campground system. The biggest pain is opening and closing the valve when the slide is out. I have to get on my hands and knees and crawl under the slide, so I've made an extension handle for the valve. I used to just leave the galley valve open, then realized the only thing that was keeping the odor from the sewer system out of the trailer was the little bit of water in the kitchen sink trap.
I like the idea of connecting the 2 tanks together though.

You can get saddles tees to do what OC did if you are even LAZIER than him!

Other options include installing an electric gate valve for push of the button opening and having a slink connected at all times... I have separate galley and grey tanks too, except FR got it right with locating my galley drain forward of my slide. I do carry enough slinky, fittings and supports to have both connected to CG sewer so I just have to open valves when in need of a drain during long stays.

I have drained several ways. It really depends on where and how long I'm going to be there. Additionally, I'll even use a combination of hose to honey wagon, just got to keep a eagle eye on the combo thing. Do you want just an overnighter drain or are you staying at a resort? Maybe its a ranch residence of sort? Some places have very strict rules. So I carry a box with several bagged and tagged tools. Or I'll take the quick way and just use the slinky hose from the rear bumper and move it to each outlet. I too have a three variable connection setup. Two basic types are "garden hose" (I use a water wye to connect the grey drains to a single garden hose) or use slinky connectors. Using the greywater cap to GH, on the outlet of the RV and Single/dual slinky drain to the sewer are my most common ways. I'll post some pics of the more popular tools I use.

I have the same set up as Capt. Mike. Have had no problem in 3 years.
