Toilet has acquired bolshie ways.

Bowl drains very slowly. Still working, water gets down to normal level, ‘substances’ disappear.

Often some burbling and burping from toilet bowl. Suspect blockage of some kind in pipe beyond bowl, to main drain/sewer pipe.

Poured bucketsful of warm water down there. Use mop covered with garbage bag as plunger. Hefty plunger effects.

Have tried drain/sewer ‘snake’ cable.

No effect.

How old is the sewer connection?

House was built in 1992, i believe. We got here in 2012.

OK, so not clay pipes. By description you have done most of the stuff a handyman can do.

I would suggest asking your neighbours whether they are having troubles. If they are, then problem belong local council and should be reported ASAP. Council will likely have a water-jet-cleaning truck or similar and will clean out the council mains.

Similar happened to us in Armidale. Turned out that someone upstream had flushed baby clothes down the dunny and that had blocked the council sewer just downstream from our toilet, in a sewer bend.
