Everything that gets flushed down the loo or poured down the kitchen sink enters the sewage pipes under your home. Most household pipes are only 10cm wide and it doesn’t take much to clog up them up.
If you tip fat and oil down the sink, it cools down, congeals and hardens on the insides of pipes causing a build-up. No amount of washing-up liquid or hot water will shift it.
Imagine the potential damage caused if wet wipes and sanitary products get caught in this congealed mess. Pipes would block and sewage would back-up into your home or yard, causing an awful mess and costing thousands of dollars to fix.
