    I have a Jobo CPP-2 that I am beginning to use with decent results.
    I level the Jobo by placing the level on the bottom of the upper basin (the red one) and my Jobo appears to be correctly levelled.

    When I pour chemicals in it through the "lift" I notice, some 4 or 5 seconds after pouring, that the sink pipe of the Jobo throws liquid.
    The sink pipe is typically already trickling before I pour, but some seconds after I poured the chemicals I can clearly see some accelerated dripping.

    That is particularly evident when I pour bleach, which is dark, so I know that what is dripping is actually the bleach I have just poured into the lift.

    No big quantities, but certainly a bit disturbing, and worth of further enquiry.

    Do you observe the same effect? (Please do check next time).
    Do you level the Jobo by placing the level on a different spot?
    Is this a problem with the red gasket on the lift?

    Thanks
    Fabrizio

    Per the manual, if you fill too quickly it will overflow. Pour more slowly. For me, when doing a process with 900cc, it takes quite a while to get all the solution into the lift, so I adjust my timing appropriately.

    The instructions also recommend placing the level on the drum itself when inserted in the processor. It says the machine may be slightly off level, but as long as the drum is level, it is fine.

    Thanks a lot. I'll place the level on the tank (Jobo 1510) and will pour more slowly.
