the parts of a toilet Should Know before buying a new one

Toiletries provide basic human necessities, and they are elegantly simple. In recent decades, minor aspects of the toilet have been changed, but fundamental components are largely the same. 

The bowls on the base were laid out for sitting. This separate unit attached to the bowl collects water from the water sources of the house when installed. 

The tanks will then pump the waste into the container and then carry the waste into the sewer. So, understanding parts of a toilet is crucial to a successful treatment for toilet problems such as leakages and clogs.

What are the 2 main parts of a toilet?

The toilet tank actually consists of two parts: a water tank valve and an empty tank valve that allows water to flow from the water tank, also known as the toilet bowl.

It is designed to hold water and is connected to the drainage pipe to remove wastewater. 

The tank, located behind the pot, has reserves of water for replenishing the bowl and the device for clean flushing water into the bowl and refilling the tank.

Toilet tank 

Toilets are a lower part of bathrooms sitting at the top of the sink. A toilet tank contains water released while flushing the toilet. 

Toilet handles attach to the toilet tank. Toilet containers are porcelain solids. Without moving components, they usually do not fail. Occasionally toilet tanks break. 

Hairline cracks in toilet tanks are repaired by washing the inside and sealing the cracks with silicone plumbing epoxy.

Toilet tank parts diagram

The Toilet Tank Diagram shows you the components and their structure. Toilet tanks can be manufactured from molded plastic or polyurethane, with the exception of the flushing chain.

Parts inside the toilet tank

The interior has fewer moving parts. Often water leaking problems result from broken parts of a toilet tank. The anatomy of a toilet tank is simple and holds enough water for flushing.

A Chained

The toilet chains also called lifts, are a small piece of metal-connected chain that connects toilet levers to the bathroom flapper. 

When the toilet lever is depressed, the toilet chain is pulled up, which raises the flap of the toilet. 

Since toilets are frequently used, it’s not uncommon to see them break. Occasionally the chains can still be fixed by cutting wire. 

Make sure the brand is new. Chains are available for flapper and toilet repair kits as well.

A Flapper

Toilet flappers are rubber stops that attach to the bottom of a toilet tank and move water through it. The toilet flapper operates using a toilet chain. 

Once it has evaporated, the flapper is pulled out to the bottom, and the flapper is closed. The toilet flapper is resistant to cracks when used. 

It can be a cause of constant leakages in bathroom fixtures. A new bathroom flapper can be obtained with a single purchase or installed individually.

A Fill valve

A toilet fill valve is a device that controls the flow of water into the bowl of a toilet. It is usually located inside the tank, whose main purpose is maintaining a certain water level in the bowl. 

The fill valve also controls how much water is discharged when the flush lever is pressed.

Many toilets have a float attached to the fill valve, which rises and falls with the water level. When the water reaches a certain level, the float activates the fill valve to allow more water into the tank.


The toilet float is a round plastic ball that can be placed over a toilet tank and float on the water. Suitable for use. 

Floats control how much water reaches the toilet. When toilets don’t float anymore in tanks, it is best if it has been replaced. 

Symptoms that indicate that a toilet needs floatation include water flowing when the tanks are full; tanks not fully filled; or continuous operation of toilets.

An overflow tube

An overflow tube is a safety device that allows water to escape from a tank or container if the pressure or level of liquid inside becomes too high. 

Overflow tubes are commonly used in residential and commercial plumbing systems, as well as in industrial applications.

Overflow tubes are typically made of plastic or metal and are attached to the top of a tank or container. 

The other end of the tube is open and usually extends above the level of the liquid inside the tank. If the liquid level rises too high, water will flow out of the tank through the overflow tube.

Overflow tubes are an important safety feature, as they help to prevent tanks from rupturing or exploding due to excessive pressure. 

They are also used to control the liquid level in a tank and can be used to drain water from a tank when necessary.

A Flush Valve

A flush valve is a device that helps to cleanse the toilet bowl by allowing water to flow into it from the tank and then flushing it out. 

This action removes any waste or debris that may be present in the bowl, leaving it clean and fresh. 

A good flush valve will also help keep the bowl free of clogs by allowing water to flow freely.

Tank O-Ring Seal

A tank o-ring seal or tank-to-bowl gasket is molded from a large oval-shaped rubber or wax washer or gasket. It tries to prevent leaks into toilet tanks.

The most common reason sewage leakage occurs below the toilet bowl while the toilet is above its bowl. This solution would require emptying and replacing the o-ring with another.

What is a toilet bowl?

The toilet bowl is the lower part of sanitary appliances. Bowls are the big surfaces where the user sits. Many toilet bowls are constructed out of vitreous china, which has an open hole and is resistant to water damage.

Generally, two forms of toilet bowls can be purchased – a round bowl or an extended bowl. 

Its oval shape is inclined towards the walls – comfortable to handle the round-shaped toilet – is ideal for smaller and small bathrooms.

A cylindrical-shaped inner trap holds discarded material. It also provides a small reserve in the water that can protect against leaks and odors in the homes.

Parts of a Toilet Bowl

The parts of toilet containers are buried within the structures without the use of moving parts. Gravity moves waste through bathroom traps in the lower half of sanitary units.

Toilet Seat

It usually sits in bowls. It has been designed accordingly. Before purchasing toilet seats, ensure the shape is either rounded or elongated.


The lid protects the toilet seat by covering the toilet and acts as protection when removing the lid and flushing. The bacterium may prevent the spread of bacteria to other animals or water.

The lid protects the toilet seat by covering the toilet and acts as protection when removing the lid and flushing.


A toilet bowl rim is the top edge of a toilet bowl. The rim is usually about 15 inches (38 cm) from the floor and is where the toilet seat is attached. 

The rim may also have some tiny holes called rim jets for a flush handle or other flushing mechanism. If the toilet has a tank, the rim will also have a hole for the fill valve. 

The toilet bowl rim can be round, oval, or square. A rim designed with a rim to prevent spillage.


A toilet S-trap is a type of drainage system typically used in toilets. It is designed to trap sewage and other waste products in the toilet bowl, preventing them from flowing into the home’s plumbing system. 

The S-trap gets its name from its shape, which resembles a backward “S.” 

The S-trap is installed between the floor and the bowl of the toilet. When waste enters the bowl, it flows into the trap and is diverted to the home’s sewer line. 

The water in the trap prevents sewage and other waste products from coming back up through the drain.

S-trap Keeping sewer gases from entering the home and helping to keep the bowl of the toilet clean by trapping waste. Toilet S-trap are found in both residential and commercial properties.

Toilet Covers and Bolts

A toilet seat cover is a hygienic way to protect yourself from germs when using a public restroom. Toilet bolts are the hardware that secures the toilet seat to the bowl. They come in different sizes and materials, but all serve the same purpose.

Toilet floor-mounted Bolts

Toilet bolts, also known as closet bolts, are essential to any toilet. Toilet bolts attach the whole system to the floor. 

The flange is a ring that sits on top of the bolts and is bolted to the floor. The bowl is then set on top of the flange and attached to the bolts. 

The tank is the last piece to be attached to the bowl and bolted to the bowl. Altogether, these pieces make up a toilet.

If any of the bolts become loose, it can cause problems. The bowl may rock or wobble, which can cause leakage at the base.

Toilet Parts Under the Bowl

Some other parts are present under the bowl and are as important as the toilet tank and bowl.

Floor Flanges

The floor flange is the round welded bracket installed over sewer pipes and beneath toilet bowls.

The floor or closet flange is securely secured on the floor through screws. The toilet is connected via a T-bolt to its flanges. 

When exposed to leaking water, floors can crack or rust and cause shakiness and prone to water leakage. 

A toilet leaking on its bottom is often caused by leaking floors, a broken wall seal, or both. This solution involves replacing the toilet flange.

The Wax Seal & Ring

A wax seal is a cylindrical gasket that fits between the bottom flanges of the bathroom linings. It’s meant to prevent water from leaking out of toilets. 

Wax seals are one use only. The wax seal may be cracked when a toilet is damaged at its base. 

To make this work, clean the bathroom and remove the wax rings from it before they’re used and replace it.

How does a toilet work?

Learning how toilets function can help you understand how everything in them works together. A simple mechanism of the toilet is- 

A toilet works by flushing waste away with water. The water is stored in a tank and then released into the bowl when you flush the toilet. The bowl is shaped, so the waste is pulled down into the water and then out of the bowl.

Press Handle. The valve is lifted so that the water can exit the water. Water filled the Bowl. The water flowed through the hole and swirled into the bowl. 

During the pumping, the fluid flows from the tip into a traphole. Gravity forces the sludge down the trapway, which will transport debris into it. 

Water flows into the water through a suction pump. Suction results from water pressure. This forces the liquid into the trapway and drains water through the primary drainage hole. Toilets refilled with water, if necessary.


The handles on the toilets are levers in the toilet tanks that flush the water. The handle is sometimes not a lever but rather a small lever on the toilet hood.

Double flush toilets have 2 buttons: one for re-use and a third for disposal of solids waste. The toilet handles are attached to a long arm that reaches into the tank. The ends on the arm push the chains to release a flappy release. 

Occasionally the toilet handle will malfunction, but the hand inside the tank may bend or deteriorate after repeated usage. 

It can be done by bending the metal arms to a straighter position. Removing bent arms from the body or replacing them with replacement plastic is advisable.

Tip: Use a toilet nozzle to help remove most clogged toilets from the sewer. Occasionally, the augers are needed to move the obstruction in the opposite direction.

Q1. What are the plumbing parts of a toilet?

Flanges. Wax seals. Handles. Floats. Chains. Flappers.

Q2. What is the thing in the back of the toilet called?

Tanks: There’s a section in the toilet where the water is stored to flush. The toilets have also been installed. Changing valves control water supply at toilets.

Q3. What do you call the back of your toilet?

The toilet bowl has toilet seats and sanitary tanks. Back of toilets are sometimes known as the “tanks.” The tanks contain water to allow for use after the user has used a toilet and activated the flushing mechanism. The tank’s interior has a handle that is activated.

q4. What is the main part of the toilet called?

The toilet flush valve allows water to guzzle into the bowl during the flush and fills the toilet tank.

q5. What is the top part of the toilet called?

The toilet tanks comprise part of the upper part of the toilet that rests above the toilet bowls. The water is collected from flushes of toilets. It’s connected to a toilet tin in a plastic container if needed.

Q6. How do I identify my toilet parts?

What do toilets look like? Toilet models are displayed on many products. Model numbers are arranged in the tank. Two-piece Toilet: The model number is on the tank and the bowl, reflecting the parts that make up the toilet.

Q7. What is the toilet pipe called?

PVC pipes are widely used for plumbing because they are light, compact, and blockage-resistant. 

PVC plumbing may be found in a bathroom or kitchen drainpipe but can also be used as a water pipe in the home.

q8. What are the components of a cistern?

Components in a Toilet Cistern Three basic components are required to provide water to this cistern, including a valve and a pump system. This base of cisterns connects to the line that supplies the water to the water supply.

Q9. What Is The Cistern Part Of A Toilet?

This is a cistern that you can use in your bathroom. Imagine a toilet with an L shape, and cisterns represent its upper, lateral part. The cistern or tank contains the water required to prepare the toilets after the water is used.

Q10. What Exterior Toilet Plumbing Parts?

This plumbing includes part of how the water flows out of the bathroom and includes the water piping in the bathroom.

Q11. What are the four types of toilets?

The four types of toilets are flush toilets, pour-flush toilets, pit latrines, and composting toilets. Each type has its own advantages and disadvantages.

Flush toilets are the most common type of toilet in the developed world. They are easy to use and require little maintenance. However, they use a lot of water and, if not properly maintained, can become breeding grounds for bacteria and other pathogens.

Pour-flush toilets are similar to flush toilets but use less water. They are common in developing countries where water is scarce. However, they can be difficult to use and maintain and, if not properly maintained, can also become breeding grounds for bacteria and other pathogens.

Pit latrines are the simplest type of toilet. They consist of a hole in the ground covered with a lid or slab. Pit latrines are easy to construct and require no water. However, they can be unsanitary if not properly maintained, and if not located far enough away from homes, can lead to contamination of groundwater.

Composting toilets are the most environmentally friendly type of toilet. They use no water and turn human waste into compost that can be used as fertilizer. However, they can be expensive to construct and maintain and require a lot of space.

Q12. Do Toilets Come With Internal Parts?

Toiletries are usually separated from their own and do not have seating. Select seats that suit your bathroom décor and bathroom colors.
