Gray water valve

[3330]

I'm getting this 2003 Designer Legacy ready to travel this fall. It's not been on the road many miles in the past, it's been parked in a spot since at least 2004. The previous owner left both the gray water valves open all the time and only cycled the black water valve to drain that tank. Now that I'm getting it roadworthy I find that one gray water valve is leaking. I know all about replacing valves but this one is going to be a royal pain. I'll try to upload a photo for illustration. It's positioned back under the shower and accessed through a removable grill in the LR. The kicker is that it's far enough in there that I can just get one hand around it and not much more. Lots of luck changing it, eh? I'm thinking about getting a twist-on valve for the dump end of the pipe and hope that the valve frees or cleans itself over the next trip or so.

I always use a twist on valve on the end of the sewer pipe for insurance. This would work until you could fix the gray valve or it fixes itself.

Thanks for the reply, Don. I've got that twist on valve on there today and no more drips. That's what I call a shade tree overhaul
