An ordinary toilet tank holds about two gallons of water.
Most earthbound toilets are made from porcelain, a non-porous ceramic, but airplane toilets are made of stainless steel.
If the water supply has been cut off temporarily, it is possible to flush a toilet manually by just pouring a bucket of water into the bowl. This activates the siphon effect and flushes the toilet.
In urban areas, the waste goes into the sewerage system; but in rural areas, it often flows into a septic tank.
The toilet tank acts as a bucket of water. When this large amount of water is quickly dumped into the toilet bowl, the siphon is activated and the toilet flushes.
The toilet tank float operates a lever that opens and closes the water refill valve.
When the flush handle or button is pushed, a linkage in the tank lifts the flush valve and allows water to fill the toilet bowl.
If the toilet tank float were to malfunction, the water would flow into the overflow tube and keep flowing out through the siphon until it was turned off.
Porcelain is a hard, non-porous material.
It takes about 30-60 seconds for a toilet tank to fill with water. If you hear water running after that interval, check your float.
The waste is constantly drained into the siphon and if several gallons of water where quickly added then the toilet would flush.
During flushing, some of the tank water flows into the toilet bowl via holes in the rim.
The flush valve, when lifted, allows water to pass into the toilet tank.
All toilets have three main components: bowl siphon, flush mechanism, refill mechanism.
Toilets come in different sizes. If your toilet measures twelve inches from the wall to the floor bolts then you have a standard size toilet.
Some toilets are installed with a wax seal placed between the toilet and the sewer pipe drain.
Do not over-tighten the floor bolts as this may crack the porcelain.
The flush valve must resituate itself to cover the drain hole before water can fill the tank.
Today's toilets come in many designer colors other than white.
