Rick's right, you do need to get the drainage sorted out otherwise the worms will drown. In the meantime, would it be possible to put some sort of container under the faulty tap ( left turned on as much as you can) to catch the worm juice? You could then decant that into, say, empty milk cartons to save it.
I had a wormery yonks ago, and remember being amazed at how much liquid it produced. But in the end, I found it to be a bit too high maintenance, so I went over to regular composting with dalek bins.
