Question: how many litres of water does flushing the toilet use?
Answer: They ideally allow for a normal, full flushes of 5 litres (1.4 gallons) as well as half-flushes which are great for liquid wastes. These toilets have been becoming more popular and are the best environmental decision as they, on average, use less than 4 litres (1.1 gallons) per flush.
