Baby and the bathwater. (Emptying trays)
All right. Never mind the baby, but the bathwater is what I'm concerned about. Yesterday, I decided to do some prints in the new to me 16x20 trays. Everything went well for a while until I decided to call it quits for the night. That's when all hell broke loose. I wanted to pour the solutions back into the containers. Well, balancing the huge tray with a gallon of developer in it while trying to pour it out into the funnel which sits on top of an empty gallon jug is an exercise of frustration to put it mildly. In the end I ended up with more than a half of a gallon of Anso 130 spilling onto the floor and splattering on everything that was standing around me, me swearing at the top of my lungs and my family thinking that the world war III has started.
For the second tray, I used the "hose over the edge and suction to start the flow" trick to drain my fixer, which went comparatively well, but I'm not sure I would want to repeat it with the selenium toner - somehow sucking poison via hose does not sound too enticing to me.
Anyway, what do you guys and gals use to empty these monster trays? Please share your tips and tricks.
Hmmm -- you might consider an intermediate step using a pitcher or bucket with a molded pour spout to dump the tray into. I find even at a much smaller scale, a funnel on top of an empty bottle is totally unreliable, unless you have just the right bottle (maybe heavy glass, which has its own hazards) and just the right funnel. Or maybe you could glue up some PVC pipe to form a support rack for a bottle and funnel.
You can also start a siphon by laying the whole hose, or most of it, in the tray to fill it then putting a finger (maybe in a rubber/vinyl/nitrile glove) and stopping the end while you lift it over to the destination. I wouldn't advise mouth suction -- ever!

I use 5L of liquid in 16x20" trays and some training did the trick for me.
One hand on each side of the tray, pouring from one corner and using the right elbow to support the opposite corner. Most important is to avoid sudden movements as not to create waves.
If you put a hose in the liquid and fill it, then cap the end of it while getting it inplace to siphon, you won't have to put it in your mouth. You'll get better with practice. Did you get Paterson trays?

A bit of latex tubing, a length of 1/4 inch I.D. tubing, and you can siphon off every drop without spilling a drop.
No need to suck the tube completely full.
Just draw enough liquid to fill the loop hanging over the counter lip.
This is a very easy-to-clean set-up, no valves, bulbs, or other gimmicks. The latex tubing won't fight you like the vinyl stuff. It lays nice and quiet wherever you put it...

Or this.. squeezing the bulb starts the syphoning. Once the hose is full, it runs as an ordinary syphon would.

With single tray processing you can put the tray on a wide pedestal slightly smaller than the tray (say, one of those melamine cubes from the hardware store, as long as it's stable), then use a wide mouth container shorter than your pedestal, and just tip the spout end of the tray to flow into the container. Hope I'm 'splaining it well enough...
Do you run water through it between trays to prevent cross-contamination?

Big trays particularly when full get a wave action that seems almost impossible to control
I have tried siphons but not found them durable or particularly fast
