I really like my Combi-Pan tank for processing 4x5 films but I have never been thrilled by the length of time it takes to fill and drain the tank, especially when doing E-6. It takes 20 Seconds for the Combi to drain and about 30 Seconds to fill with the little funnel provided. (Although, in all honesty, I haven't seen any degradation of the processed film, it still bugs me that it takes a minute to switch chemicals!)
Well, I must have too much time on my hands because I found myself experimenting in the shop to find a quicker method to fill the Combi. I resisted the urge to use pressure (for fear of blowing the top off the tank ;-) ) but I did find a rig that lowers the fill time to 17 Seconds. The best part is that it is cheap, easy, and doesn't require any special tools to make.
Cheap plastic garden hose (if warmed) will fit the Combi filler neck very well. Of course garden hose fittings are also cheap and a female garden hose end ALMOST fits the neck of a 2L plastic pop bottle (except the threads don't match), so I took the barbed fitting from the female garden hose fitting and cut a hole in the plastic bottle cap to fit (replacing the metal ring that comes with the garden hose fitting with the bottle cap). With a couple of inches of old hose, a garden hose "washer" and the fitting it makes a 2L funnel for the Combi that doesn't leak. Being able to dump the full 1L of chemical into the "big funnel" cuts the fill time to 17 Seconds! It is really more simple than it sounds!
