Avoid blockages / faults?

 How can blockages and faults in the domestic sewerage network be avoided?

The toilet bowl is not a waste-paper basket. Avoid throwing sanitary products and rubbish into the toilet bowl

Place a waste-paper basket near the toilet bowl.

Place a protective mesh over the plug-hole of each sink or washbasin
Leftovers from working at the sink should be thrown in the rubbish.
