Kitchen sink not draining, maybe airlocked?

So the Karcher drain cleaner worked perfectly. Soil pipe is clean now and the sink drains like never before. It took about 3 hours to clean 15m of very badly blocked 110mm soil pipe. Thanks everyone for your input.

Well done you! I’m not sure it was going to shift it.
