Gray Water & Sewer Drainage

I have a HW296.
Any suggestions for attaching the gray water drainage to the sewer drainage, so that you don't have to keep switching out at the campsite.

Just guessing here.

You have two gray tanks and one black tank one gray has it's own dump connection, right?

If so and you are using a Rhino or similar type hose.

Drainage

Yes of course I meant gray vs. black. Yes we have the rhino system for the black.

Are you using one hose for black and another one for gray?

If you have the where with all, you can permanently hard plumb the back tank to the forward tanks. Takes about 4 hours and $25 worth of pvc pipe.

If you have 2 grey tanks and 1 black tank. You can purchase a connection at the sewer inlet that has an additional water hose fitting. Also will need a fitting/cover at the camper grey water outlet. You can then use a standard water hose (not a white fresh water) to connect at the camper cover and the sewer inlet fitting. You can also use the "Y" fitting as Ford Idaho suggested. You would have to purchase or make up three sewer hoses. One sewer hose from camper grey water outlet to "Y", one hose from camper black water outlet to the "Y" and another hose from the "Y" to the sewer inlet fitting. Both methods work. For both methods, when at the destination, you would leave the grey water tanks open, but close the black water until 3/4 full. Close the grey water camper outlets prior to dumping.

Oldcoot,

I like your suggestion. Much better. But how did you connect both ends, black tank to forward grey tank? Did you cut holes in the side of both the size of pipes (3 inch), then glue pipes in? Please explain in detail? Could the grey tank be plumbed to back black water tank? Thanks ................

Cut a 1-1/2" hole in rear galley tank discharge tube and glued a pvc pipe into it and ran it forward into the front black/grey tank discharge pipe with a shutoff valve in between.
