How to merge 2 separate waste hookups, one gray/black water, second gray wate...

[ChiefGeek]

Our new Puma 32DBKS has 2 waste water hookups, is there a way to merge them into one? One is from the bathroom (gray/black) the second from the inside and outside kitchens (gray only). Our RV will be on a seasonal site, semi-permanent, with one sewer hookup.

Rhino hoses makes a Y connector. You run two hoses into one. Bit of a pain, but..

I have the same set-up on my sabre 34 Tbok. I used the valterra hose connector that has the option to hook a garden hose on the 90 degree elbow. From there run a piece of garden hose to your kitchen only grey tank drains and use the 3" to garden hose adapter on the camper. Been doing it this way for 3 years and have had no issues at all

I use the garden hose with a 3" inch to garden hose bayonet adapter on the camper. I then took a regular I then drilled a hole in a Rhino 90 degree elbow at the sewer dump site. I then installed a garden hose male connection with rubber washers allowing me to hook the garden hose to drain into the 3" elbow with the regular 3" hose from the other tanks.

Mine are pretty close. I have resisted the flush master one outlet mod. I just move the hose and dump the galley tank after about 4 days when on Full Service. Some day a OC plumb them together mod.

The method I described (not very well) prevents you from moving the hose. It just results in a garden hose draining your dish water and a regular "3" Rhino hose draining your black and other grey tank.

A permanent fix is to hard plumb them together and add a shutoff valve where they hook together. Takes about 3-4 hrs and $15-$20 and it's finished with no future hassles with y pipes and multiple hoses, etc.

I went with Rhinoflex for both with a valterra 3" shutoff at the "y" to segregate the front hose (galley drain).

OC, how did you tie into the elbow coming off the bottom of the tank? I've thought about doing the same thing to our Sabre 34TBOK as a way to expand our grey water capacity. We always find that the bathroom grey water always fills up and our other two grey tanks never get more than half full.

I've used two sewer hoses, a Y, and a cap to transfer in pinch but then you have two hoses full of grey water to deal with.....

Very carefully laid out the outline of the new pipe and cut the hole and hand filed it to fit tight and used pvc glue to secure it. Did the same on the front elbow for the new pipe fit into it.

Nice, thanks everyone, I haven't been out to the RV for a few weeks so I can't submit a picture of the Puma hook-ups, but one (BR B&G) is close to the front of the TT, and the kitchen (G) is just in front of the tires. About a 10' spread in between if I remember correct. May use the Y adapter for now, and in the spring or summer of '15 do a perm. job like OldCoot, great job on that BTW.
