Toilet Bowl Flush System Installation and Repairs
Toilet bowls in Singapore generally have a great flush system, and a good system can prevent problems such as a clogged toilet. The toilet cistern is the part that holds water at the back of the toilets. The toilet flush button releases the water through the toilet flush system to wash the content of the toilet bowl into the septic tank.
Problems with your toilet flush system could prevent your toilet from flushing properly. This can be a tricky situation especially if you only have one toilet in your home or apartment. There are many issues that can occur with a toilet cistern or the toilet flush system. While most times, you may be able to do it yourself, we recommend that you should call a professional plumber to help you with your toilet flush repair.

Just call us at +65 6653 6258 with details of your toilet problems and a technician will be deployed to your home for an on-site assessment.
Types of Toilet Flush Designs
In the Singapore market, there are many types of toilet bowls to choose from and you would want the best for your home. And each toilet bowl flush system is different from the other types of flush system. Here are some of the flush systems that are available in the market.
- Basic Flush Tank: This is one of the most common types of toilet flush systems in Singapore. It comprises a flapper valve that is activated once the toilet flush button is depressed to drain water into the toilet. This then allows water to enter the tank which raises a floating ball that shuts off the water supply at a level.
- Dual Flush Tank: This is designed to let users select two different levels of water usage depending on how much waste is available. The partial flush is designed for liquid waste whereas the full flush is for solid waste. This is more environmentally friendly and helps to save water in your toilet. It also helps with the cost utility bills and saves money too.
- Pressure Assisted Toilet Flush System: This type of toilet bowl uses a high-pressure system that allows the toilet to use low flush volumes of water compared to other toilet flush systems. This system is noisier compared to other systems.
- Elevated Flush Tank: This is one of the older flush systems that have since been replaced from most HDB flats. Although you can still see them in squat toilets. This flush system makes use of a floating ball valve to enable the flushing to happen when the chain is pulled on.
- Double Cyclone Flush System: This is one of the latest flush systems where it uses two nozzles instead of rim holes. Assisted with a propulsion system, more water is directed to the cistern generating a more efficient flush than the rest of the systems.
Types of Toilet Flush Problems
When it comes to toilet flush systems, it is by no means without its own complications. We have collated some of the common problems that are associated with the flush systems.
- Weak flush
Toilets sometimes have a “weak” or “lazy” flush after several years of use. If your toilet would not flush after you pushed the toilet flush button, then you need to check out a few things to find out why. Sometimes, there may not be water in the toilet cistern. This could be as a result of water being turned off or low water pressure. If the toilet flush valve is also leaking, this could prevent adequate water from staying in the toilet cistern. Once the flush valve and gaskets lose their water seal qualities, water would keep draining from the toilet bowl.
If your toilet flush system is of the first generation made during 1994 to 1997, you will highly likely have a weak flush experience. You may check inside the flush type to look for the manufacturing date stamped into the clay. These toilets often time will have sediments deposited in the siphon jet hole which will cause the flush to be weak. If the flush becomes weak, and the waste accumulates and hardens, this will result in a toilet bowl choke, which will likely become more complicated, and in such cases, it will be advisable to look for a plumber to solve this issue.
- Partial flush
Partial flushes can be quite strong, but it is still an incomplete flush, which will be an issue to home owners. The possible reason for this could be due to the fact that the flapper valve may be waterlogged (full of water) or being diminished too quickly. During a flush, the flapper valve should stay up until about 80% and above of the water has been drained off. If the flapper does not stay up until then, it is likely that your flapper is the main cause of the partial flush.
- Phantom flush
Phantom flushing is a phenomenon that occurs when the toilet flushes by itself without any human interaction. This is commonly caused by water slowly leaking out of the cistern and into the toilet bowl due to a worn-out flapper valve. When the flapper becomes a burden to the toilet system, it will enable water to keep draining, forcing the tank to constantly refill and drain, and the process repeats itself, causing a massive wastage of water.
- Double flush
A double flush occurs when there is too much water leaking from the toilet tank and into the toilet bowl. As you know from above, worn out flappers can be the cause, but a lightweight flapper causes the double flush. The flapper acts as a doorway to allow stored water from the tank to flow through. If the flapper is a lightweight, or if it is fitted wrongly, it will not be able to close swift enough to prevent more water from flowing through, causing a second flush to happen.
Another cause can be due to having too much water in the tank. The extra water will flow out when you press the button for the tank to flush, refilling the tank quickly causing the toilet to flush twice. As to why there may be too much water in the tank, this is likely due to the toilet fill valve being set poorly.
- Whistling tank
Having a whistling tank may not seem like it could be a problem, but a whistling tank is actually a sign of a problem that is to come. The whistling is usually associated with a faulty fill valve. As time goes by, the fill valve will experience wear and tear and its internal components will deteriorate resulting in the whistling sound. The faulty valve can also cause the entire toilet bowl to vibrate, leading to weird noises from the toilet bowl. A faulty fill valve will cause a leakage into the toilet bowl, increasing the water usage, thereby increasing your utility bill and cause the imminent problem that is to come.
- Slow fill
When the toilet bowl tank has a slow tank fill, there are a few reasons as to why this happens. It may be a case of a semi-open valve from the water supply line causing the water to slowly fill the water tank. Another possibility would be due to a clog in the supply line. This happens when a foreign object enters the stream. Low water pressure can also cause the tank to have a slow fill. In this case, the pressure pump will likely be the main culprit as it may be faulty.
- Leaking tank
A toilet flush system tank may leak due to a faulty supply line, a crack in the porcelain or even a faulty part within the flush system. The leakage can leak into the toilet bowl or even the external area around the toilet bowl.
- Flush button spoil
When you try to flush the toilet, and pressing the button does not activate the flush, it is most likely that the toilet cistern is faulty. A toilet flush cistern (also known as toilet flush valve) is part of the main body that holds the water back. When the button is pushed, the hold is released resulting in a toilet flush. Therefore, when the button mechanism is spoil, it may be due to faulty part of the cistern.
No matter what kind of system you may have for your toilet bowl, if it breaks down, you will have to get it changed. Even if you do not know how to go about changing the toilet flush system, it would be good to have some knowledge as to how it is replaced. You can always engage a reliable plumber to help you with the replacement.
Toilet Flush System Replacement
When a toilet bowl stops flushing and the toilet flapper is in good shape, a toilet flush system replacement may be needed. The general outline as to how a replacement is done are as such:
- Turn off water supply
Begin by turning the water supply off. Place a container below the water line to catch any rogue water. Remove the water line from the toilet.
- Remove toilet tank
Remove the nuts that hold the tank onto the toilet bowl and carefully remove the tank off, and set it in a safe position to work on it.
- Remove the bolts
The mounting bolts that support the structure of the toilet bowl may have another set of nuts holding onto the toilet tank. Remove the nuts first. If the toilet bowl is old, the bolts will likely be rusty. So, it would be good to cut them off with a mini hacksaw.
- Remove the old flush system
Remove the flush system nut by using a large pair of pliers. Once the nut is loose, put the flush siphon out from the top of the tank. Clean up any residual stains before installing the new toilet flush siphon.
- Installing the new flush siphon
Having an adjustable flush siphon would be ideal so that it can adjust to any height needed, although most siphon are also universal, and this may not be necessary. Ensure that the flush siphon gasket goes into the tank, and the nut and washer on the outside of the tank by following the appropriate angle before tightening the nut. Fit the tank to the bowl gasket over the flush siphon on the bottom of the tank.
- Installing the tank bolt
Make use of tank-to-bowl bolts that contains a washer inside the tank and another on the bottom of the tank for each of the bolts. Then tighten the nuts onto the bolts.
- Set the flush tank on the toilet bowl
Ensure that the toilet bowl is aligned between the holes in the toilet bowl. Following that, set the tank onto the toilet bowl and install the washer and wing nuts. Tighten the nuts by hand and fill the tank with water, allowing the weight to push down onto the toilet bowl before tightening further.
- Connect the water supply
Attach the flex line onto the toilet tank and turn on the water. Adjust the flapper chain onto the toilet handle. Adjust the height of the flush siphon if needed so that the water level remains at the recommended line and the overflow is just about 2.5cm above it. Do remember to detect any water leaks by flushing the toilet multiple times.
If the steps for the flush system replacement seems daunting to you, you may want to engage a reliable and professional plumber that can help you with all your plumbing needs.
Why would I need toilet flush replacement or repair?
Common reasons for a toilet flush replacement are water leakages. This could occur with a leaking tank due to a faulty supply line, a crack in the porcelain, or a faulty part in the flush system. In other instances, a leaking flapper valve is deteriorated or improperly sealed, causing water to constantly flow into the toilet bowl even without flushing.
What are the different types of flush systems in Singapore?
These are the different types of flush systems available:
- Gravity flush – This is the most common type of flush system used. Flushing is influenced by gravitational force and weight of the volume of water that creates pressure needed for flushing.
- Pressure assisted flush – This particular system makes use of air under pressure to force water into the toilet bowl. This prevents the toilet bowl from getting clogged. Although this system is a little noisy, it gets the job done well.
- Dual flush – Allows full flushing for solid waste and partial flushing for liquids, saving water in the toilet bowl.
- Double cyclone – An eco-friendly option that combines the twin power of gravity and a water spiraling technique to clean the toilet bowl as it flushes with the use of two powerful nozzles.
What are the common toilet bowl issues?
When used frequently, toilet bowl issues are bound to happen. These problems are such as a toilet bowl choke, slow tank fill, waterlogged flapper valve dropping too quickly, and wear-and-tear of the wax/rubber ring between the toilet base and the drainage pipe.
How to choose the right toilet bowl for your home?
If the problem is too severe and needs replacement, here’s how you can choose the right toilet bowl:
- Type of toilet bowl – A one-piece model has a sleek appearance and consists of a toilet bowl and tank fused into a unit. A two-piece model consists of a separate tank and bowl and is widely used among Singaporeans as it is more economical.
- Type of operational style – Varying operation style such as gravity type flushing action, vacuum-assist flushing mechanism, or a pressure-assist toilet mechanism that can clear wastes with a pressured “push”.
- Toilet bowl design – Modern toilets are available with different configurations to match various needs. Choose from toilet bowls that are round-front, compact-elongated, or elongated. Check the location of the flush-handle, potentially positioned over the top lid or on the right/left side of the tank.
- Height of seat – Chair-height toilets have their seat about 48cm over the floor, while standard-height toilets have seats at 43cm in height and custom-height toilets have them at a height of 38cm to 71cm over the floor.
- Type of flushing system – Many types of flushing system such as gravity flush, pressure assisted flush, dual flush, double cyclone, and more.
