Interesting - you mean that the blade is sticking in the open position? I would have expected the problem more likely to be that the handle pulls out of the blade leaving the blade in place and the tank closed & full of waste water that you cannot release.
I have often wondered what I would ever do if that happened - I have some ideas but don't know if they would work!
If you are drilling a hole for a screw in the same endplate where the handle comes out, what does that allow you to do?
Do you then insert a rod and lightly tap with a hammer directly on the end of the blade to free it and get it to close?
If so, couldn't you just do that by using a hammer directly on the end of the normal operating rod?
Maybe I misunderstand - and you are talking about a valve that is stuck closed and maybe the handle has pulled free from the blade making it impossible to dump teh tank?
It does make we wonder if what you describe, but drilling the hole on the sllde end plate at the OPPOSITE end of the slide, away from the operating rod/handle end could then allow you to insert a rod and tap open a stuck slide where the handle had pulled out of the blade leaving the blade stuck in place.
IE in order to be able to dump the tank and then work on replacing the defective valve.
I haven't looked closely enough at one of the valves to know if that might work.
