Key takeaways
- Fat sets as it cools and builds up in layers on the pipe wall, often well past the trap under the sink.
- Slow draining, gurgling, a sour smell and dishwasher water backing into the sink are the early signs.
- A drain cable punches a hole through the fat; hydro jetting scours it off the whole pipe wall, which is why jetted lines stay clear longer.
- Hunter Water says cooking oils, fats and food scraps belong in the bin, not the drain.
