How much water does a toilet cistern hold?

Answer 1

a toilet cistern holds 3216
Most modern toilets will hold about 20 litres, but they are being made smaller all the time due to better flushing designs and the need to conserve water. Toilets can all be adjusted internally on the fill valve to hold less water. The new recommended flush amounts in many countries is 13 or 6.5 litres.

Answer 2

All toilet bowls are simple containers of water, shaped as a U to allow water to remain within and prevent the nasty drain smells from escaping into the room (yuck!)

The level of water remaining in the toilet bowl is at exactly the same height as the tip over point at the back of the U.

There are two usual reasons why the water level would be lower in the toilet bowl.

Firstly because of human interaction (sticking a brush in and agitating the water for example)

Secondly due to formation of a vacuum due to incorrect or inadequate venting (this is best left to professionals to assess but essentially means any change in pressure through the drain causes the water to be usually 'sucked' out therefore leaving a low water level in the bowl)
