Toilet Tank Parts

The toilet tank is an essential component of the toilet system, housing several important parts to ensure proper flushing and refilling.

Below, we break down toilet tank parts, how they work, and tips for fixing common issues.

1. Toilet Tank

The toilet tank is the main reservoir that holds water used for flushing. It is typically made of ceramic and is designed to store a precise amount of water, ensuring an effective flush.

The tank also houses various internal mechanisms that work together to regulate water flow and flushing.

How Does a Toilet Tank Work

The toilet tank stores the water required for flushing. When you activate the flush handle or button, the tank releases water into the bowl via the flush valve.

Afterward, the fill valve refills the tank to prepare it for the next use.

2. Toilet Flush Handle or Two Flush Buttons

A toilet flush handle is usually located on the side or front of the tank. It is a lever that lifts the toilet chain inside the tank.

Two flush buttons found on modern dual flush toilets allow users to choose between a partial or full flush. They conserve water for liquid or solid waste.

How Does a Flush Handle Work

The flush handle is connected to a lever inside the tank, which pulls the toilet chain to lift the flapper. Dual-flush systems use buttons to achieve a similar result, offering a lighter flush for liquids and a full flush for solids.

How to Fix a Toilet Handle

If your handle feels loose or doesn't work, check the connection to the lever. Tighten any loose nuts or replace a worn-out lever. If the handle is broken, you may need to replace it entirely, ensuring compatibility with your tank.

3. Toilet Supply Line

The supply line is a flexible pipe that connects the home's water supply to the toilet tank. It ensures the tank is refilled with water after each flush.

It includes a shutoff valve, which allows you to control or stop the water flow during repairs or emergencies.

How to Fix a Toilet Water Supply Line

The supply line connects the toilet tank to the water supply. If it leaks, check for loose connections or damaged washers. Tighten the nuts or replace the supply line if necessary, ensuring you shut off the water before making repairs.

4. Toilet Chain

The toilet chain is a small and adjustable link that connects the flush handle to the flapper. When you press the handle or button, the chain pulls the flapper open, allowing water to flow from the tank into the toilet bowl.

Proper chain tension is essential to avoid weak flushes or water leaks.

How to Fix a Toilet Chain

The toilet chain connects the flush lever to the flapper. If it's too loose or tight, adjust the chain length to allow smooth operation. Replace the chain if it's broken or rusted.

5. Toilet Flapper

The flapper is a rubber or plastic valve located at the bottom of the tank. It controls the release of water during a flush by sealing the flush valve opening. A damaged or worn-out flapper can cause water leaks or flushing issues.

How to Fix a Toilet Flapper Valve

The flapper controls the release of water during a flush. If your toilet runs continuously, the flapper might not seal properly. Replace the flapper if it's warped or degraded.

Ensure you make a flapper compatible with your toilet model.

6. Toilet Float

The float is a buoyant device that controls the water level in the tank. As the tank refills after a flush, the float rises and shuts off the water supply once the optimal water level is reached.

Improper float adjustments can cause overflows or insufficient flushing.

How to Fix a Toilet Float

The float regulates the water level in the tank. If the tank overfills, adjust the float height using the screw or clip on the float arm. If the float is damaged, replace it to prevent leaks.

7. Toilet Flush Valve

The flush valve is a key toilet component that sits beneath the flapper. When the flapper lifts, the flush valve directs water from the tank into the toilet bowl with enough force to clear waste.

A malfunctioning flush valve may result in weak or incomplete flushes.

How to Fix a Toilet Flush Valve

The flush valve allows water to flow from the tank into the bowl. If it leaks or malfunctions, remove the tank to access the valve. Replace the valve if it's damaged, ensuring proper alignment and sealing during installation.

8. Toilet Fill Valve

The fill valve is responsible for refilling the toilet tank with water after each flush. It works in conjunction with the float to regulate the water flow.

Modern fill valves are adjustable, allowing users to control the water level and prevent overfilling.

How to Fix a Toilet Fill Valve

The fill valve controls the water flow into the tank after a flush. If the tank doesn't refill or overfill, clean the valve's filter for blockages or replace the valve if it's worn out.

9. Toilet Overflow Tube

The overflow tube is a vertical pipe inside the tank that prevents water from spilling out. Excess water flows through the tube directly into the toilet bowl, acting as a safeguard against overflows.

How to Fix a Toilet Overflow Tube

The overflow tube prevents the tank from overfilling by directing excess water into the bowl. If it's cracked or damaged, replace it to maintain proper tank operation.

10. Toilet Tank Cover

The tank cover is a ceramic or plastic lid that rests on top of the toilet tank. It protects the internal toilet components from dust, debris, and damage while maintaining the toilet's aesthetic appeal.

If the tank cover breaks, it should be replaced to prevent contamination or damage to the internal mechanisms.

What to Do If You Break the Toilet Tank Cover

A broken tank cover can be replaced with a new one from your toilet's manufacturer. If an exact match isn't available, opt for a universal cover that fits your tank dimensions. Handle tank covers carefully to avoid future breakage.

Toilet Bowl Parts

The toilet bowl is not just a simple ceramic structure. It consists of several toilet bowl parts names that ensure smooth waste disposal and user comfort.

Below, we explore these components, their functions, and tips for fixing common issues.
