There comes a time when you must work on the stinky side. The black water valve has been leaking for years. Now that the handle is getting harder and harder to pull/push it's time to do the dirty deed.
What to do?
First option: Replace seals/caskets ($20 each) I've read where this sometimes don't work and there goes $40 and have to start over,
Second option: replace valves ($60 each) But then the valves are glued. I have had luck with cutting and breaking plastic fitting out but being able to get the 34 year old plastic separated w/o everything breaking isn't likely. So with new valves would mean new tubing. But where to find that?
Looks like the whole assembly will come out by taking the 4 screws that holds the valve into the tanks. Then disconnect the mickey-mouse setup they did to couple handle rod to the gray water valve(looks like a piece of scrap sheet medal bent aroll the shaft
Guess I'll see what breaks as I tore it apart.
