Default Great West Van Legend Lavatory Drain

I made a repair for my Great West Van Legend lavatory drain hose. I didn't have a good positive connection and the hose kept slipping off. It is a flexible moving hose connection because the lavatory slides in and out.

This is the drain receiver for the 3/4" flexible corrugated plastic drain hose. It is not a full 3/4" diameter and only protrudes 1/4" which did not provide enough bite to keep the hose attached.


I found this 38 cent PVC 3/4" male adapter at Home Depot and made modifications as you can see in this before and after photo. I cut off the screw thread and had to sand down the male end so the hose could slip over easier. With the threads cut off the adapters inside diameter slides loosely over the protrusion but close enough for the cement to make contact.


The drain pipe is ABS plastic and the adapter is PVC so I bought some Oatey ABS to PVC Transition Solvent Cement and liberally applied to all the contact surfaces. I was rather messy but it isn't suppose to be seen anyway. Solvent cement dissolves the plastic and essentially welds the pieces together rather than just act as a contact cement.


So far it seems to be holding and the corrugated plastic drain hose will definitely not slip off like before. I've looked at several Great West Van solutions for this before my van was built and after. They had seemed to have solved the problem after mine with more positive connections. If anyone has an older Legend with this problem, this is a fix without a lot of major re-work.

Did you let the GWV folks know? It seems like something they could pass along to customers and dealers.

My van was built by the past owner of GWVan and not the current owner and is now past warranty. I had it "fixed" once under warranty but knew the problem would persist, usually under a month's daily use. It was a faulty design that has since been fixed by the new owner for newer Legends. I figured they had their shot and no real solution for mine. So now I came up with my own after the warranty expired. I've posted this in three different forums. I'm sure they will see it if they are monitoring the Internet. It is kind of a moot issue now as I see newer Legends have done away with the sliding lavatory. In a way it was a great idea. It made the wet bathroom more convenient for taking showers as a lavatory didn't protrude in the space yet when open gave a larger sink than anyone else with shelf space. I'm not unhappy with that aspect when it works.

Here is the hose reinstalled and tested. So far everything works fine and I doubt the hose will ever slip off again.
