Anyone having issues with their water stops not staying open or closed, the new split washers are extremely easy to install and give you back full control. We can now run with them half way open again which helps tremendously with contamination issues on the edge of the sheet.
I wish I could help not familar with your type of stops. On my Atlas stacks I cut a piece of blanket and took one of the big black paper clips to hold it in place.
We use wooden dowels, cut to fit, to keep them opened and closed.
Jim, are you referring to the sliding baffles on the Quadstack units? we have a few keys on a couple of units that move by themself. we place a small aluminum block behind them to keep them in place. I would love to know more about the split washers, sounds like a much better way to control them.
Richard we were using copper pipes to hold ours open as well. I bought 7/8' plastic washers,and cut a small 'v' out of it. You can then slide it into both sides of each baffle. Once they are in, it tightens them back up so you no longer need the blocks or pipes. I replaced them all over a couple of years ago and they are still all in and working well.
this may sound dense, but do you have a picture of the washer with the v-cut in it?
