Kitchen Sink Not Draining in Sydney
You've washed up, pulled the plug, and the water is still sitting there an hour later, which means the waste pipe under your sink has narrowed to about the width of a straw.

Questions and answers
Air is being pulled back through the sink because the shared waste can't take both at once. It is an early warning that the line is narrowing, and left alone it usually blocks properly before long.
Bail the water down to a few centimetres, seal the other outlet and plunge. If the level won't budge, the fat is set past the trap where no plunger reaches, and jetting is the fix.
Honestly, none of the bottles. They soften the surface of the fat and leave the rest, and they sit in the trap as a burn risk for whoever opens it. Jetting is what actually removes the fat from the pipe.
You can clear the strainer and bail the water out, and sometimes the level drops by itself overnight. Beyond that, a plunger is the only safe homeowner tool for the job.
Usually a bit of both. Fat causes most kitchen blockages, but a long flat run or a sag makes a line block far sooner than a steep, short one. If it keeps happening, the camera tells you which.
It depends on where the blockage sits and how long the run is. There is a $0 call-out on any job you book, and you see the price in writing before the trap comes off.
