    Using a Jobo forced film washer

    I just picked up one of these. Seems like a simple device but I can't find any instructions online.

    If I had to guess I would say that you pop the lid of the tank but leave it on loosely, then insert the washer. So the water flows down the column and then back up and out the sides of the tank.

    Can anyone confirm or correct?

    Push it firmly into the centre opening of the tunel, open the water tap carefully, water flows out trough the openings in the tank lid. Now close the little hole on the transparent tube with your finger, this will close the air intake, the water will rise in the tube. Adjust the water flow with the tap so that the water level is steady between the two red lines on the tube, then unblock the air intake again.

    Thanks! It was a little more complicated that I thought, that is very helpful.

    OTOH, you can just let fly with the water pressure and ignore the lines. After you finally grab the hose and nozzle whipping madly around the room and clean up the mess you can follow the instructions in #2.

    This Cascade device is only intended for washing the developed and fixed film (may it be a negative or positive) in a developing tank (or photographic paper in a tray, with some holding clips).
    Especially when used in a tank it uses the water most economically as all water passes the film at near distance.

    Jobo washer from a Jobo manual

    Here is their own photo of the washer. They do call it a "cascade", but I just don't associate that name with this device.

    And my only wall decorating was done with a Kodak style emulsion mixer made for me by a friend. When we first tried it, lets just say it "overperformed" a tiny tad!

    That water running over the tank over a staggered relief makes the term cascade quite appropriate.
