In the age of do-it-yourself home repair projects, knowing as many details as possible about the project being worked on is vital. Bathroom toilets are one of the easiest items to repair for do-it-yourself fans, but the first thing to do is understand the basic toilet bowl parts and how they work together. Once the basic toilet parts are well understood, repair jobs become much easier to handle.
At First Glance
A standard toilet is comprised of a tank and a bowl. The tank is usually rectangular in shape and sits flush against the wall. It is covered by a removable top that allows access to the mechanisms within. The bowl can either be round or elongated and oval in shape. The majority of the functioning toilet bowl parts are contained within the tank itself.
Toilet Components
The two external features of the toilet tank are the tank lid and the tank handle. The external handle is connected to the flush valve which rests on the bottom of the inside of the tank. The interior of the tank also includes a filler valve, filler float, and an overflow tube. The toilet bowl includes the two-piece toilet lid and the siphon, which is simply the curved area at the base of the bowl itself.
How The Toilet Bowl Parts Work Together
By pressing down on the handle, the flush valve is lifted up, allowing the clean water in the tank to pass into the bowl. As the water level in the tank drops, the filler float lowers within the tanks as well. Once the float reaches a certain level, the filler valve opens to allow fresh water to fill the tank until the float returns to its original position. The water pressure created by a full tank will then return the flush valve to it’s closed position. In some cases, if the float valve continues to run after the filler float has risen back to the top of the tank, the excess water would flow into the overflow tube. In the bowl itself, as the clean water is passing in, the dirty water is pulled down the bowl through a suction process, passed through the siphon, and then pumped to the sewer or septic lines.
