Thanks, Redwood, for locating the gray tank waste valve above and hidden by the black tank so that it is impossible to replace the valve or cable without removing the black tank. Real forward thinking considering valves and cables wear out or get plugged and need occasional maintenance. The location of the gray tank valve cannot even be seen from below. I used a bore scope to look at it. The cable on my gray tank valve pulled out of the handle. It's a relatively easy and inexpensive replacement if there was access. So stupid because there is excess plumbing in which the valve could have been located WITH accessability. Grrrrr. :angry:

How do they do it... take what should be an easy job and making the fix hard!

Terry,

Thanks for posting this issue and the brake wiring, I have passed them both onto Redwood to see if they have already been addressed, or can be with engineering changes.

I agree.......... I have a grey tank valve that has become plugged and won't allow draining of the tank. I took the bottom liner down while I was in Florida and the valve gate seems to be operating but nothing comes out of the tank. So, I am assuming that the tank cutout may be plugging the opening. It would be good if the engineer that designed this layout had to come fix this issue so he/she could experience getting dumped on due to the lousy layout design!! The grey tank valve is located directly above the black tank valve making it very difficult to access. I had to replace the black tank valve and cable last summer and I remember thinking and hoping that I would not have replace that grey tank valve any time soon..........I guess "soon" is now upon me. This will now be one of my repair tasks this summer back here in Indiana. It also appears that there is some grey tank drain line plumbing leaking under there so this is just not going to be any fun!!! 😉 😉 :angry: 👿 :sick:

Just curious! Is there a spot in the basement that you could cut an access hole to repair the valve & hinge the piece for future access? Just thinking out loud & most anything would better than laying underneath dealing with the black tank & getting "dumped on".

Maybe. The valve is beneath a step behind the rear bulkhead wall in the basement. (The converter is mounted on the step.) Difficult to access the area because of a maze of water piping, drain line and wires. If I could get access it would be somewhat of a guesstimate as to where to make the cutout but it's an idea worth investigating. I have a Fein plunge saw that could make the cuts without endangering what is beneath. Unfortunately no way to get my head up into the area of the valve from below to see what may be interfering. I can feel part of the valve with my hand and try to use my borescope to get somewhat of a visual at the area above the valve.

I would just remove the black tank as it will eventually fall anyway. That way you will kill 2 birds with one stone. Repair the grey valve and support the black tank better than the factory when you put it back in

ORRRRRRRRR...Get more of the same.... 🙁

Wait until you have rebuilt half or more of your rig...

Just saying...

I'm off the box now.
