The current set-up on my coach has all the piping and valves are 3 1/2 inch, making it difficult to find a camco type sewer hose. I would like to change the last dump valve (grey water bypass) to 3" but so far have been unable to find a 3 1/2" to 3" adapter. Any thoughts from those of you who have done this?

Thanks
John

Have you tried Camping World John? You can also check here or give these companies a call if it's not listed on their sites they may still have one in stock for what you are wanting.

Jon, We use a "Rube Goldberg" adapter. Have the original "j" slot piece, then had to clamp short brown flex hose on it. Clamped a "connector" to brown hose, then on out with the"orange" collapsing flexible hose.

Newell also has these. But probably easier to get from Dupree.
I bought a connector so I could make an adapter for my sewer solution and was going to use a short hose also but the valterra connector fits into the Dupree connector snugly. A bit of silicone and it works great.
