Black tank valve

[denandra2]

I am in the process of replacing my black tank valve and am at wits end. I can't get the flanges far enough apart to get the new rubber gaskets on and then put the new valve in place without dislodging the gaskets. Has anyone had any experience doing this? How do I spread the flanges apart and what do I use to keep them apart.i have thought about cutting the valve out and the with couplings put it back together. That just doesn't seem a good answer as I would have to cut too much pipe. The lines under my 320 are in a very tight space. Can anyone offer any ideas.

Thanks

You may have to remove brackets holding the 3" piping in place, which is what i had to do. Then when you have some wiggle room, have your wife hold the pipe back while you hurry and situate the valve in.

I have the bracket at the outlet where you connect sewer hose and not much give at all. The 3 inch pipe is right up against a cross brace.

Just glue the gaskets to the new valve with contact or rubber cement, use bolts to make sure the gaskets are aligned.
