Black and gray water leaks

Good evening, this is my first post but I am not new to full timing. We have a 2004 Fleetwood Providence 39L and have been experiencing some problems with Gray water and Black water leakage. It started out with the black water valve leaking so I replaced the valve about a year and a half ago.
What a mess, all the plumbing/valves are in between the two tanks. It was very difficult to get the valve out and I could not get the new valve back in. I ended up disconnecting the valve on the gray water end of the piping which aided in getting both valves back in but still not a easy job at all.
To make things worse now I think both valves are leaking now plus the gray water is dripping from the bottom of the valve blade.
I did notice that both tanks have two large stainless clamps around the tank where the fittings go into the tank. It makes me wonder if the clamps were loosened, could the fittings be slipped back into the tanks a bit allowing easier access and installation of new valves. I questions how these fittings would be sealed, O rings??? So hopefully someone will know how to take care of this issue, it is cold here, so I know that my facial expression might look like one of this little guys at some point during this project.
This is were I will wish I could be, but if one ya'll can fill me in on a cure this problem I will look like this

Your plumbing is just black plastic that slips inside the tank and then is tightened by the SS clamp that you're seeing. You might be able slip the plumbing back into the tank some, but you'll probably find it hard to move.

When you replace the valves, do both at the same time. I think you can buy both from Camping World for about $25.00 and even cheaper on line. Use a 1/4 drive socket set with a swivel to get to the nuts and bolts. When reassembling, use some Vaseline to hold the seals in place and help slide the valves back in. The Vaseline won't hurt anything.

Lastly, the valves will leak when debris gets stuck in the seals. This can be caused by pushing the valve shut while there is still junk coming out. Make sure you do a good rinse before closing the valves. A little WD-40 on the valve rods (where handle is attached) will help the valves work better and smoother.
