    Is there a bung or a pipe at the bottom of the tank? Just drain the entire contents of the tank. Flush it out with diesel or clean oil if you want to be thorough. The water shouldn't have gone beyond the tank if the digger wasn't started.

    On the left hand side of digger at the side of tank there is a hydraulic pipe about inch half thick going into tank and a screw type bolt of similar size below that, not sure I will be able to get all liquid out as this sitting a inch up and digger facing down hill, maybe there another bung somewhere or do you know or does anyone here know, thanks

    There should be a bung underneath the tank. It’s forward of the front axle.
    There are suctioning strainers inside of the tank, which are accessed through a removable round plate on the right hand side of the tank. It would be advisable to clean them while the tank is drained...

    They had an oil sump pump in lidl lately. That would empty the tank for you

    I hate those things but they're not that bad in the case where you're taking good albeit used oil out. But in this case you really want to get all of the contaminated oil out. You won't be able to do that with a pump.

    Might be no harm to change oil after a few hours use.
    You might have to do this a few times.

    Similar issue at work once where a hydraulic system was filled with coolant and the machine was run until the vane pump failed.
    New pump and 2 oil changes and all was OK.
    Original valves are still in the machine.

    This machine wasn't started, so the water shouldn't be gone any further than the tank. The only possibility would be that it went into the return pipe, but I'm not familiar with the set up to know if that was a possibility.
    But obviously, as you say, it should be checked for milky oil for a while after changing the oil.
