Hey Scott, you can use the Valterra Bladex Waste Valve Body part # T1001VP to replace your current valve body. Once you unbolt and slip out what you have you can then replace it with this and bolt it in place and you'd be set. Thanks for the picture!

Thanks I can't tell without disassembly, I have water in the tank already, I am not near a dump site. I am unable to see assembly with the rest of the plumbing. pix always help. Experience also counts and I have no experience replacing this particular connector/ slide valve.

@ScottB Yeah I would make sure you have the tank empty before attempting to replace the valve so that pulling the valve out doesn't create a huge mess.
