So it looks like I am back to one of my most favorite past times, working on plumbing.
I noticed that the gray water blade valve was dripping a little bit on our last outing, time to address that.
Before I started this project, I filled and flushed both the gray and black water tanks three times.
The blade valves (and the gray and black water tanks) are located behind the panels in this storage bay.

First step is to remove the panel with the faucet and sprayer on it (if you are following these projects you will remember that I just did this to fix the leak in the faucet.


Next the handle has to come off the diverter valve.

Now the first large panel can be removed.

And now the second one, which reviles the black and gray water tanks and the blade valves and dump connection.

The valves were removed (there are four bolts, one in each corner of the valves and once removed the whole vale comes out, a little bit of a struggle as they fit tightly together, but not bad. When I pulled the valves and seals out I laid them out as they came out so I would know how to reinstall them.

I then cleaned up the surfaces of the ends of the pipes that will remain. Remember what pipes you are dealing with here, wear rubber gloves, and clean your hands if you walk away from this project.


I had anticipated having to wait on parts (I did not want to order parts until I had it all apart so I would not have to place several orders), but, when I ran over to Brad's Trailer Hitch they not only had the parts on the shelf, but they had the same brand name parts.
Here you see the old parts and the new parts side by side. The new valves came with new nuts and bolts, new seals, and the valves.

I replaced both valves, and the dump fitting so I would not be doing this again next month. They were cheap, do not scrim here buy them all.
Below is one of the seals out of the black water line, it was the only damaged seal I found, but it was the gray water valve that was leaking.

Here is the new and the old one side by side.

All though the instructions said to just put the seals in place I like to coat them with some silicone grease (not petroleum grease as it will attack the rubber). This is the pipe out of the black water tank. The seal slides onto the flange of the pipe.

This is the seal on the flange of the dump fitting.

So now everything is bolted back together. The toughest part of this job is to slide the last valve in place without dislodging the seal on the end of the flange. To insure that I had not done that I connected up the hose to the flush fitting and filled both tanks to their full marks. I let it sit for an hour while I went and eat lunch. When I came back there were no drips. I also took the time to wipe everything down before putting the panels back on.

Another project done.
