FLUSHING a toilet uses more water than many are aware and that is due to the older cisterns a lot of loos are still kitted out with.
If you flush the toilet five times, that can use about 45 litres of water, about a third of the average daily consumption per person, say German consumer advisors.
But more modern toilets are far more economical, for example models that have a flush-stop button. They only use 3 to 6 litres per flush, rather than 9 litres.
The same applies to what are known as dual-flush toilets. Their flush tanks have two buttons, one for a small amount of water and one for a large amount.
The more modern toilets might save water but they are still just as hygienic as those with older cisterns with higher water consumption.
If you replace your toilet cistern, you can reduce your water consumption by 30% to 50%. Meanwhile the cost of converting the toilet will have paid for itself within one year, the experts say. – dpa
