Question:

On a recent outing in northern Utah I mistakenly followed Google directions and ended up on a roadinch that our 1994 SMB had no business being on. It took us about a hour to get the beast turned around and out of there. Besides some scratches and dings, I thought all was ok and considered myself lucky to get the rig home in one piece. Today I went to the car wash and got down to dump our gray water, only to discover that our complete gray water mechanism was gone...valve, support, spigot, gone! Photo attached. Im guessing that Im not the first guy to be so stupid to take a old van down a 4 wheel drive goat track and snap off parts. Wondering how I should approach repairing it? ID of the drain pipe is 1 1/2, but was broken off so remnants of the original are in the way. Many thanks for your thoughts and assistance. At 165K, Harvey our van still has some life left in it and Id like to come up with a fix other than a bucket underneath if its possible.

You can use the Valterra Waste Valve # T1001B to replace what has broken off, as it is a 1-1/2" diameter pipe that is designed for gray water systems. The challenge, as you're aware, is what to do about the broken pipe that is lodged there. You can try to chip it out and use a small length of PVC pipe to replace the broken end and attach it to the # T1001B with some ABS Solvent Cement # A05-0303.

That's really the only way you're going to be able to accomplish this without cutting off other sections and trying to replace them with some plumbing supplies like a rubber gasket, clamp and more PVC pipes. You should be able to source these parts from a local big box hardware store.
