thinking of switching to electric valve for my blackwater side. cable has failed for second time. i haven't dropped belly to see whats wrong yet. i know the electric is about twice as high in cost ove...
Both the gray and black valves got to be difficult to operate on our FW after 3 years. I did a Google search for "lubricating rv dump valves" and got many suggestions on how to fix. I used the "drill a hole in the valve gate housing and squirt in silicone" procedure and now they work very well. Don't know how long the silicone lasts or other side effects, we'll see.
