Toilet Flush System Installation, Replacement & Repair

Toilet Flush System Installation, Replacement & Repair in Singapore

Everyone in the city of Singapore knows that a well-functioning toilet flush system is essential to maintain hygiene and efficiency in any bathroom. Even toilets account for almost 30% of an average home’s indoor water use.

When someone upgrades to a high-efficiency toilet, they can save up to 13,000 gallons of water annually. This is why toilet flush system installation, replacement, and repair service in Singapore is important. 

According to statistics, around 3 gallons of water is wasted per flush of the toilet every day. If your toilet has issues like leaks or weak flushing, then this waste may rise significantly. Not only water waste, but a lot of worse things also happen due to toilet bowl or flush system problems. 

Won’t you think of getting assistance from professionals like Li Fong Handyman? We cure your burden of using a nasty, non-functional toilet tank or flush system. Our years of experience, knowledge, and methods of service can easily provide you with fresh, running, and long-lasting restrooms. 

Types of Toilet Flush Systems

A flush tank or flush system varies in design and functionality. These varieties offer different levels of water efficiency and performance. In Singapore, you may find these types of toilet flush systems:

Single Flush System

A single-flush system uses the same amount of water for every flush. It may be typically around 6 liters per flush. You can find this standard system in many older toilets.

Dual Flush System

Another interesting flush system – dual flush offers two options: a full flush for solid waste (usually around 6 liters) and a half flush for liquid waste (around 3 liters). This design helps conserve water and reduce utility bills.

Pressure-Assisted Flush System

This third type of flush tank uses pressurized air to force water into the bowl. As a result, the user gets a powerful flush from the tank. This system is more efficient at clearing waste. But it has two issues – noise and more expensive to maintain. 

Gravity Flush System

Can you recall Newton’s gravity? Well, the gravity flush system relies on the natural force of gravity to move water from the tank to the bowl. This is the most common type of flush system. It is known for its simplicity and reliability.

Double Cyclone Flush System

It features two nozzles that create a powerful cyclone of water to clean the bowl. This system is efficient as it uses less water per flush than traditional systems.

Tankless Flush System

You can notice these tankless flush systems often in commercial settings. They use a direct water supply to flush the toilet. Additionally, these systems can save space and water. However, they require a strong and consistent water pressure.

Toilet Flushing System Parts

Toilet Flushing System Parts

Multiple essential components work together to ensure proper flushing and water management in a toilet flush system. 

Flush Valve

The flush valve controls the release of water from the tank into the bowl. When you press the flush handle, the flush valve opens. It allows water to flow into the bowl to flush away waste.

Fill Valve

The fill valve (or the ballcock) refills the tank with water after each flush. It is connected to the water supply line. Also, it regulates the water level in the tank.

Flapper

The flapper is a rubber or plastic seal that sits on the flush valve opening. When you flush, the flapper lifts. It allows water to flow into the bowl. Then, it reseals the opening to let the tank refill.

Flush Handle

The flush handle, or lever, is connected to the flush valve via a chain or rod. When you press the handle, it lifts the flapper and initiates the flushing process.

Overflow Tube

The overflow tube prevents the tank from overflowing by directing excess water into the bowl.  Plus, it helps to maintain the correct water level in the tank.

Float

The float is a buoyant device attached to the fill valve. It rises and falls with the water level in the tank. This way, it signals the fill valve to stop or start refilling the tank.

Chain or Rod

The chain connects the flush handle to the flapper. When you press the handle, it pulls the chain or rod to lift the flapper and allow the flush to occur.

Tank

The tank holds the water used for flushing. It houses all the internal components of the flushing system. The tank ensures a sufficient supply of water for each flush.

Bowl

The bowl is the part of the toilet that holds the waste. It is connected to the tank. Also, it is flushed clean when you release water from the tank.

Wax Ring

The wax ring is a seal between the toilet base and the floor drain. It prevents leaks and ensures a secure connection.

Toilet Flushing System Replacement Cost

Replacing a toilet flushing system involves several components which we have already discussed. Hence, the replacement cost varies depending on the type and quality of the parts. You need to count labor costs with the price of parts. 

ItemCost Range (SGD)
Flush Valve$15 – $50
Fill Valve$20 – $60
Flapper$5 – $20
Handle$10 – $30
Labor$50 – $150
Total$100 – $310

You need to spend around $100-$310 USD to replace a toilet flushing system (including labor costs). However, high-end parts or complex installations may increase the overall cost.

Toilet Flushing System Replacement Kit

You should have the right kit (like we do) to make the replacement job smoother and more efficient. In a kit, there must be:

Tank-to-Bowl Bolts

You can secure the toilet tank to the bowl with these bolts. The kit should contain bolts with washers on both ends to ensure a tight seal and prevent leaks.

Washers and Wing Nuts

Besides the bolts, these nuts are also helpful in securing the tank. The washers provide cushioning and sealing. Alternatively, the wing nuts allow for easy tightening by hand.

Flex Line

You may find it by another name – the water supply line. It connects the toilet tank to the water supply valve. It’s crucial to fill the tank after each flush.

Flapper Chain

This chain links the flapper to the toilet handle. It allows the flapper to open and close during flushing. You must have the correct length and tension of the chain for proper flushing operation.

Flush Valve and Flapper

The flush valve is the opening at the bottom of the tank through which water enters the bowl during flushing. The flapper seals this opening between flushes. 

Adjustable Height Flush Siphon

Some kits may offer adjustable height flush siphons. They can accommodate different water levels in the tank for optimal flushing performance.

Instructions and Tools

Yes, these non-physical components are also considerable as required tools. If you are doing the job alone, these instructions will be valuable.
