Generally, a toilet outlet has the shortest trap seal, making it most vulnerable to being emptied by induced siphonage. An additional risk of pressurizing a system ahead of a waste stream is the potential for it to overwhelm a downstream trap and force tainted water into its fixture. Serious hygiene and health consequences can result.
It is designed to allow a shorter interval between flushes than individual cisterns. Flushing troughs were commonly used in places such as schools, colleges, public toilets, factories and public buildings where repeated use of the flushing cistern was required in a short period of time. Such troughs were used by local councils in the UK into ...
A flush toilet (also known as a flushing toilet, water closet (WC); see also toilet names) is a toilet that disposes of human waste (i.e., urine and feces) by collecting it in a bowl and then using the force of water to channel it ("flush" it) through a drainpipe to another location for treatment, either nearby or at a communal facility.
The modern toilet utilises a cistern to reserve and hold the correct amount of water required to flush the toilet bowl. In earlier toilets, the cistern was located high above the toilet bowl and connected to it by a long pipe. It was necessary to pull a hanging chain connected to a release valve located inside the cistern in order to flush the ...
Some toilets also use the siphon principle to obtain the actual flush from the cistern. The flush is triggered by a lever or handle that operates a simple diaphragm-like piston pump that lifts enough water to the crest of the siphon to start the flow of water which then completely empties the contents of the cistern into the toilet bowl.
Aerosol droplets produced by flushing the toilet can mix with the air of the room, [8] larger droplets will settle on surfaces or objects creating fomites (infectious pools) before they can dry, like on a counter top or toothbrush; [7] [10] and can contaminate surfaces such as the toilet seat and handle for hours, which can then be contacted by hands of the next user of that toilet.

A dual flush toilet; note the two buttons at the top of the cistern. A dual flush toilet is a variation of the flush toilet that uses two buttons or a handle mechanism to flush different amounts of water. The purpose of this mechanism is to reduce the volume of water used to flush different types of waste.
Whilst a dry toilet can be with or without urine diversion, a pit latrine is almost always without urine diversion. The key characteristic of a pit latrine is the use of a pit, which infiltrates liquids into the ground and acts as a device for storage and very limited treatment. [7] Pit latrines are sometimes also referred to as "dry toilets ...
