What Are the Parts of a Toilet? How Do They Function?
One of man’s most wonderful inventions has to be the modern toilet! Let’s face it—this is something we use several times a day, but we really never give it a thought until it fails to function properly. When that happens, the plumber becomes not only our new best friend but also our knight in shining armor! Are you even familiar with the toilet parts in your porcelain throne?
Unfortunately, it seems like the toilet malfunctions at the worst times possible, like on Christmas Eve when you have a house full of guests. If you familiarize yourself with the toilet parts and how they function, you can do the simple repairs. You’ll no longer be at the mercy of a professional plumber, and you’ll save money by avoiding those expensive house calls.
- Bowl: The round part of the toilet that holds water and waste.
- Tank: The back part of the toilet that holds the water used for flushing. It also houses the working toilet parts.
- Stop Valve: This controls the water supply to the toilet. It’s usually located on the wall behind the toilet. You can turn this off manually.
- Supply Tube: Connected to the stop valve, this tube carries fresh water from the main water supply to the refill tube.
Toilet Parts Within the Tank
- Float Ball: The float ball floats on top of the water in the tank. It signals the water supply, letting it know when the tank is full.
- Float Cup: On many newer toilets, the float ball has been replaced by a float cup that is located on the valve body. It rises and falls with the water level. When it reaches a pre-set height, it closes the ballcock valve on the refill tube.
- Refill Tube: When the float ball falls to a certain level, the refill tube fills the tank (and thereby the bowl) with fresh water. When the float ball rises to the top of the tank, the water supply is shut off.
- Ballcock: A valve at the top of the refill tube.
- Trip Lever: When you press the handle to flush the toilet, this lever lifts the flapper.
- Chain: The chain connects the trip lever to the flapper.
- Flapper: When the flapper is lifted by the trip lever, suction is created, causing the flushing action within the toilet bowl.
- Overflow Tube: This stops the toilet water running over. If the tank gets too full, the extra water drains into this tube.
Toilet Parts Under the Bowl
- Wax Ring: This is located under your toilet. It’s what your toilet sits on. When the toilet is set on the wax ring, the wax expands, creating a tight seal.
- Trap: The trap is located under the toilet bowl. It separates the main sewage line from the toilet.
- Closet Bend: This is the part of the sewage line that allows waste materials from the bowl to exit the home.
