Flushing Cistern: Water Closets (WC), Urinals

Flushing Cistern

A flushing cistern is a simple water tank that stores water and then releases it quickly to clean the toilet or urinal after use.

When someone uses the toilet, we need water to wash away the waste. That’s exactly what a flushing cistern does. It holds clean water and, with just one push or pull, it throws the water with force into the toilet bowl. This helps keep the toilet clean and fresh.

It is also called a water waste preventer because it gives just the right amount of water needed to flush — not too much, not too little. This saves water and keeps everything hygienic.

So, in short —
A flushing cistern stores water and sends it out with pressure to clean toilets or urinals after use. It’s a smart and simple way to keep things clean.

Flush Tank –

A flush tank is a container that holds water for flushing the toilet. It is usually fixed right behind the toilet seat. When you press the flush button or handle, the water from this tank goes down into the toilet bowl to clean it.

Most toilets you see today are made in two parts – the tank (which holds water) and the bowl (where you sit). Both parts are made from a strong, smooth material called vitreous china that is easy to clean and lasts a long time.

Inside the tank, there are some simple moving parts. These parts work like a team. When you flush, they let the water flow quickly into the bowl. This is called a gravity flush – it uses the power of falling water to clean the toilet.

So, the flush tank may look simple, but it’s very important. It keeps water ready all the time, so your toilet stays clean with just one push.

Bell Flushing Cistern

A bell flushing cistern is an old-style water tank used for flushing toilets. You’ll usually find it in very old buildings like schools or factories. It is made of strong cast iron and holds about 5 to 15 litres of water.

This type of cistern needs to be installed high above the toilet to work properly. Inside the cistern, there is a special part called a bell, which is connected to a chain and a lever.

Here’s how it works:

• When someone pulls the chain, the bell lifts up.
• This makes the water in the tank rush down through a pipe.
• The water flows quickly because of a siphon effect—this means the water gets pulled out strongly, just like sucking through a straw.
• This gives a fast and powerful flush to clean the toilet.

Once the chain is pulled, it should be let go quickly so that the water can flush properly.

The cistern fills with water again using a float valve (also called a ball valve).

• When the water level goes down, the valve opens, letting water in.
• When the cistern is full, the valve closes to stop more water from coming in.

It also has an overflow pipe, just in case something goes wrong.
If the valve doesn’t stop the water, the overflow pipe safely sends extra water away so it doesn’t spill into the toilet or bathroom.

Today, this type of cistern is not used much anymore, but you might still find it in very old places. Even though it’s old, it gives a strong and fast flush, thanks to its smart design.

Automatic Cistern

An automatic cistern is a special kind of water tank that is used to flush urinals without needing anyone to press a button or handle anything. It works on its own!

These cisterns are mostly used in places where a lot of people come and go—like bus stands, railway stations, schools, offices, and other public places. Since many people use the washrooms in these places, these cisterns help keep everything clean by using water regularly.

They use a lot of water because they flush again and again, all by themselves. This helps keep bad smells away and keeps the place neat for the next person.

Automatic cisterns are simple, smart, and very helpful—especially where cleanliness is important all the time.

Which Cistern Type is Best for You?

Choosing the right cistern for your bathroom is easier than you think. Let’s look at a few simple things that can help you pick the perfect one:

1. How Big Is Your Bathroom?

• If your bathroom is small, go for a concealed or compact cistern. These are hidden or smaller in size, which saves space and gives a neat, clean look.
• If you have a big bathroom, you can choose a high-level flush cistern. It looks classic and adds charm to the space.

2. What Style Do You Like?

• Want a modern and stylish bathroom? A wall-hung cistern with a floating toilet looks sleek and smart.
• Prefer a traditional or vintage look? An exposed cistern fits beautifully in old-style bathrooms.

3. Do You Care About Saving Water?

Of course, we all should! Choose a dual-flush cistern. It uses less water and helps save it with every flush.

4. Easy to Fix? Or Just Good Looks?

• Concealed cisterns look nice but are a little harder to repair because they’re hidden.
• Exposed cisterns are easy to fix and perfect for homes where things need to be done quickly.

5. Strong and Long-Lasting?

Cisterns are made of PVC, ceramic, or metal. PVC is light and affordable. But no matter what you choose, pick one that lasts long.

6. What’s Your Budget?

• Want to save money? Go for a simple, exposed design.
• Want a modern look and can spend a bit more? Try a concealed system — it’s worth it for the style and space it saves.

7. Need Flexibility?

Some cisterns can fit with many types of toilets — wall-mounted or floor-mounted. These are great if you want choices in design.

8. Want a Quiet Flush?

In quiet homes like villas or apartments, a low-noise flush is best. It keeps things peaceful, even at night.

9. Hot Weather Worries?

In hot places like the UAE, choose a cistern with good insulation. It helps avoid water droplets (condensation) and keeps everything working smoothly.

How to Choose the Right Cistern for Your Bathroom?

Choosing the right cistern is like choosing the heart of your toilet. It helps save water, keeps your bathroom neat, and makes flushing smooth. So, let’s understand how to pick the best one for your home — in a simple, easy way.

1. Size of Your Bathroom

Think about how big or small your bathroom is.

• Small Bathroom? Go for a concealed or compact cistern. It hides inside the wall and saves space. Your bathroom will look neat and modern.
• Big Bathroom? A traditional high-level cistern is a great option. It hangs higher on the wall and looks classic. It also gives a strong flush — perfect for bigger spaces.

2. Match with Bathroom Style

Your cistern should match your bathroom’s overall look.

• Modern style? Choose a wall-hung cistern with a floating toilet. It hides in the wall and gives a clean, stylish feel.
• Old-school or vintage look? Pick an exposed cistern. It’s visible and adds charm — like the good old days.

3. Save Water Smartly

Water is precious. So, choose a dual-flush cistern.
It gives you two buttons:

• A small flush for liquid waste (uses less water).
• A big flush for solid waste (uses more water).

This way, you use only the water you need — and nothing extra.

4. Easy to Repair?

Let’s face it — things break. So pick something easy to fix.

• Concealed cisterns look neat, but fixing them is harder. You may need to open the wall or panel.
• Exposed cisterns are open and easy to reach. So, repairing them is quicker and cheaper.

5. Material & Strength

Cisterns come in different materials. Here’s what to know:

• PVC: Light, cheap, and doesn’t rust.
• Ceramic: Looks beautiful and is strong, but heavier and costlier.
• Metal: Very strong, but can rust if not taken care of.

Pick what suits your home and your budget.

6. Your Budget

Money matters too.

• Low on budget? Go for an exposed cistern — simple, strong, and affordable.
• Want a fancy, modern look? Spend a bit more and choose a concealed cistern. It’s worth it for the beauty and space it saves.

7. Quiet Operation

If your house is peaceful or you share walls with others, pick a low-noise cistern. Some cisterns are made to flush quietly, so they won’t disturb others.

8. Future Flexibility

If you might change your toilet design later, go for a modular cistern. It works with both floor and wall-mounted toilets, giving you freedom to upgrade later without buying a new cistern.

Water Closets (WC) –

A Water Closet, or WC, is what most people call a toilet. It is a clean and safe place where we go to pass urine or poop. The water closet is made in such a way that all the waste goes away quickly with water, keeping everything neat, fresh, and hygienic.

It is usually made of a smooth material like ceramic, which is easy to clean. When you flush, water flows from the tank and carries all the waste through a pipe, far away to a place where it is treated. This helps keep our homes and surroundings free from bad smells and germs.

There are many types of water closets. Some are Western-style, where you sit on the seat, and some are Indian-style, where you squat down. Both do the same job – to keep us clean, comfortable, and healthy.

Using a water closet is part of good hygiene. It protects us from diseases and makes life easier, especially in homes, schools, offices, and public places.

In simple words, a Water Closet is a smart and safe way to keep our environment clean and our bodies healthy.

Indian Water Closet –

An Indian water closet is a type of toilet that many people use in India and nearby countries like Nepal, Bangladesh, Pakistan, Sri Lanka, and Bhutan. It is made in a special way that helps us sit by bending our knees — just like when we squat.

This way of sitting is very natural for our body. It also helps in keeping our tummy clean and healthy.

The bowl of this toilet is shaped so that water and waste flow down easily. The back part of the closet slopes down, and there is a hidden pipe called a trap that carries everything safely into the drain. This design helps keep bad smells away and keeps the bathroom clean.

Many families in villages and cities use Indian water closets every day. They are simple, strong, and easy to clean.

Western Water Closet

A Western Water Closet is a type of toilet that looks just like a chair. You sit on it the same way you sit on a regular chair. That’s why it is very easy and comfortable to use.

It is mostly used in Western countries, but nowadays, people all over the world like using it because it is clean, modern, and good for people of all ages.

The back part of the toilet is slightly sloped, which helps the waste go down smoothly into the drain. This toilet is connected to the drain with a trap, which helps stop bad smells from coming back up.

There are two main types of Western Water Closets:

1. One-Piece Toilet – In this type, the basin and the trap are made together in one piece. It looks neat and is easier to clean.
2. Two-Piece Toilet – In this type, the basin and the trap are made separately and then joined together during installation.

Both types work well and are chosen based on style, space, and personal preference.

Urinals –

Urinals are special wall-mounted pots that are made for men and boys to pee in. You’ll often see them in public places like schools, offices, and malls. They are neat, save space, and help keep washrooms clean.

But just using a urinal is not enough—it also needs to be flushed properly to stay clean and smell-free. There are four main ways to flush a urinal:

1. Manual Handle Flush

This is the most basic type. Each urinal has a small handle or button. After using the urinal, the person just needs to press the handle to flush water and clean it.

It works very well if people remember to flush. That’s why it’s called a “manual” flush—you have to do it yourself.

2. Timed Flush

In this system, water slowly collects in a hidden tank. When the tank fills up, it flushes the urinals all by itself.

It doesn’t need anyone to press anything. It works again and again on a fixed time. Some modern systems use an electric controller instead of the water tank, but the idea is the same—regular flushing without needing help.

3. Automatic Flush

This is a smart and modern system. It uses a tiny sensor. When someone stands in front of the urinal and then walks away, the sensor knows that the urinal has been used.

It then flushes the urinal all by itself.

This is a great way to keep urinals clean and save water too. It only flushes when needed. No forgetting, no waste!

4. Waterless Urinals

These are very special. They don’t use any water at all!

Inside the urinal, there is a trap with a special liquid. This liquid floats on top of the urine and blocks any smell from coming out.

After some time, the liquid and the trap need to be changed, but these urinals save a lot of water and are good for the environment.

Types of Toilet Cisterns

A cistern is the water tank behind your toilet that helps flush the waste away. It may look simple, but it plays a big role in keeping your toilet clean and working smoothly. Let’s explore the different types of cisterns and how they work – in an easy, natural way!

🧱 1. Close-Coupled Cistern

This cistern sits right on top of the toilet bowl. It’s small, neat, and easy to install. Most homes use this type because it’s simple and works well. The flush is quick, and the water flows directly into the bowl from the tank above.

🛠️ 2. Concealed Cistern

As the name says, it’s hidden inside the wall or behind a panel. Only the flush button is visible outside. This makes the bathroom look clean and modern. It also saves space. But, fixing it may take extra effort if there’s a problem.

🧼 3. Wall-Hung Cistern

This one is mounted on the wall, and it’s used with wall-hung toilets. It keeps the floor clear, which makes cleaning easier. It looks very stylish and gives a floating effect to the toilet.

🧓 4. Low-Level Cistern

This cistern is placed just a little above the toilet bowl, at a similar height. A short pipe connects it to the bowl. It’s a classic design, mostly seen in older-style bathrooms. Still works great!

🏛️ 5. High-Level Cistern

This one is installed high up on the wall, with a long pipe going down to the toilet. You usually pull a chain to flush. It gives your bathroom a vintage or traditional look.

💧 6. Dual-Flush Cistern

This modern cistern has two buttons – one for a half flush (for liquid waste), and another for a full flush (for solid waste). It helps save water every day. Simple and smart!

🪶 7. Polymer Cistern

These are made from strong, lightweight plastic. They don’t rust, they last long, and they’re easy to maintain. Polymer cisterns are great for modern homes because they combine strength with style.

💡 How Does a Cistern Work?

A cistern has two main jobs – fill and flush.

• Inlet Valve – This part brings water into the tank. Once it’s full, it stops the water from coming in.
• Outlet Valve – When you press the button or pull the lever, this part releases the water into the bowl to clean it.

🧩 Main Parts of a Cistern

• Flush Valve – This lets water out of the tank when you flush.
• Fill Valve – This refills the tank after every flush.
• Overflow Pipe – If the water level rises too much, this pipe safely carries the extra water out. It stops overflow.

🌟 Why Are Cisterns Important?

Toilet cisterns are the heart of a modern toilet. They store water and flush waste out, keeping everything clean and hygienic. Today’s cisterns are smarter, more stylish, and save water too.

✅ Benefits of a Good Toilet Cistern
