How to Perform Drain Assembly Installation/ Replacement in Singapore
When it comes to household maintenance, one of the most common tasks is replacing or installing a drain assembly. Whether due to wear and tear or renovation purposes, knowing how to properly perform this task can save you time and money in the long run. This guide will provide step-by-step instructions on how to install or replace a drain assembly in Singapore.
What is a drain assembly?
A drain assembly is an integral part of your sink fixture that ensures water drains properly and prevents larger waste items from clogging your drain pipe. It is typically composed of several key components including the sink drain and p-trap, which are connected to the drain opening of your sink.
The sink drain, located at the bottom of the sink, catches and transports water to the drain pipe. The p-trap, a u-shaped pipe, prevents sewer gases from entering your home and catches items that may accidentally fall into the sink drain. Understanding these components is key to a successful installation or replacement of a drain assembly.
What size is a drain assembly?
The size of a drain assembly generally depends on the specifications of your sink and pipes. Most kitchen sinks in Singapore are equipped with a standard drain hole size of 3.5 inches, while bathroom sinks typically have smaller drain holes, averaging around 1.25 to 1.5 inches.
​
It's crucial to confirm the size of your sink's drain hole before purchasing a replacement drain assembly, to ensure a seamless fit and proper functioning. Pipes also play a critical role in the size selection, as the drain assembly needs to connect correctly with the existing plumbing system.
Therefore, before initiating the installation or replacement process, accurate measurements of the drains, sink, and pipes are necessary to ensure a perfect fit and prevent any leakages.
How do you measure a drain assembly?
To measure a drain assembly, you first need to deal with the small hole at the bottom of the sink where the assembly will be installed. Measure the diameter of this hole accurately using a measuring tape or ruler.
This diameter will determine the size of the drain component that fits into the sink. Next, measure the distance from the sink hole to the faucet, as this distance can impact the positioning of the pop-up lever and the drain stopper. Lastly, measure the diameter of the drain pipes that lead away from the sink.
This measurement is critical as your drain assembly must match it to ensure a proper fit and effective drainage. Always double-check your measurements for accuracy to prevent any mismatches or leakages.
Can you reuse a drain assembly?
Yes, you can reuse a drain assembly, provided it is in good condition and fits the sink drain perfectly. A well-maintained sink drain assembly can last for years, making it a potentially reusable component when upgrading or replacing a sink.
However, ensure it aligns well with the sink drain, as a poor fit can lead to ineffective drainage or even leaks. While reusing a drain assembly can be cost-effective, it's important to consider the overall condition and compatibility with your sink to avoid future plumbing issues.
How to install or replace a pop-up drain assembly?
To install or replace a pop-up drain assembly, begin by ensuring that the sink is clean and free of any debris. Place the pop-up into the sink's drain hole, making sure the rubber washers are aligned properly to form a watertight seal. The pop-up should be hand tightened to ensure it's secure, but not overly tight to prevent damage.
Next, insert the plastic P-trap - a U-shaped pipe that prevents sewer gases from entering your home - into the wall drain. Ensure that it is securely hand tightened and that the drain assembly aligns accurately with the P-trap below. The plastic P-trap is a crucial component that connects the sink drain to the drainage system.
Once aligned and tightened, run some water to check for leaks. If the assembly holds the water without any leaks, the installation process is complete. If there are leaks, adjust your rubber washers or the tightness of your connections until a perfect seal is achieved. This process ensures that your sink drains effectively and maintains a clean, dry area under your sink to prevent water damage.
What is the difference between a push drain and a pop-up drain assembly?
Between a push drain and a pop-up drain assembly, the difference primarily lies in their mechanisms and user interaction. A push drain, as the name implies, utilizes a push-and-pull mechanism where the user pushes down on the cap to seal the sink and pulls it up to allow water to drain.
​
On the other hand, a pop-up drain assembly is typically connected to a lever located on or near the faucet. When this lever is activated, it opens or closes the drain, regulating the flow of water from the sink.
​
While both types of drains effectively manage the flow of water and prevent leaks when properly installed, the choice between the two often comes down to user preference and the specific design of the sink and faucet ensemble.
How much does it cost to replace a drain assembly in Singapore?
To replace a drain assembly in Singapore, it costs approximately SGD $150 to $250, depending on the complexity of the job and the specific service provider.
​
This includes the removal of the old drain assembly, the application of a generous bead of plumber's putty, and the installation of the new one. It's important to note that this cost can vary greatly, especially if additional plumbing services are required. For instantce, if the sink drains into the wall are not aligned properly or there is a significant leak that needs to be addressed. Any variation in these factors could potentially increase the overall cost of the job.
