What Are the Parts of a Toilet? (With Diagram)

Holle likes doing simple repairs on her own toilets because those calls to the plumber can get costly.

What Are the Components 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.

The Primary Parts of a Toilet and What They Do

• Bowl: This is the round part of the toilet that holds water and waste.
• Tank: This is 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• Float Cup: On many newer toilets, the float ball has been replaced by a float cup that is located on the valve body.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 preset 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: This is the 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 from 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.

Got it? Familiarize yourself with these toilet parts and study the diagram. Bookmark the article if you need to. The next time you have a toilet malfunction, maybe you'll be able to do the repairs yourself!

Hi, Chuck. Hubby says a few Hope Depots have them. They're made by Sloan. You'll probably have to go to a plumbing contractor supply or search online.

Chuck K. on May 02, 2010:

Need a flush valve for a wall mounted residential toilet but can't find one, do you have any suggestions where I could get one.

Holle Abee (author) from Georgia on February 20, 2010:

Glad you stopped for a read, Alexandria!

Audrey Kirchner from Washington on February 20, 2010:

My blind guy could have used this a few months ago! I actually had to go on line and find a website that he could SEE with all the parts and email it to him. He lives about 5 hours from us - and then I sent over our friend just to be sure he got it back together without killing himself! I'll have to keep this for him for future reference - from penises to toilets....I guess we all know where our heads are today! Great info.

Alfreta Sailor from Southern California on February 20, 2010:

That's so true habee, we use the toilet on several occassions, yet never think about its function until it breaks down. Thanks for breaking the parts down for us - you have a great way of keeping us "in-the-know."
