Plumbing issues are among the most common household headaches in Hong Kong. Whether it's the sound of a dripping faucet in the middle of the night, low water pressure during a shower, or the terrifying experience of a burst pipe, these problems can severely disrupt your daily life. With Hong Kong's dense housing and many aging buildings, deteriorating water pipes are a widespread issue. If not addressed promptly, they can lead to more serious water leakage issues, potentially affecting your downstairs neighbors and resulting in unpredictable repair costs and even compensation claims.
As a professional home repair team, we handle numerous similar cases every day. In fact, as long as you spot the warning signs early and find the right technicians, many plumbing problems can be easily resolved. Many homeowners feel helpless when faced with plumbing issues and don't know where to start. Today, we will explain in detail the common plumbing repair issues and the correct ways to handle them, so you can respond calmly to unexpected situations.
Common Plumbing Issue 1: Dripping Faucets
A dripping faucet might seem like a minor issue, but over time, the amount of wasted water and the resulting water bills can be significant. Imagine this: a faucet dripping once per second can waste thousands of liters of water a year! The primary cause of a dripping faucet is usually the aging or wear and tear of the internal O-ring. The water quality in Hong Kong sometimes contains fine sand and stones, and long-term friction can accelerate the wear of these rubber washers. Additionally, frequent use or excessive force when turning the faucet on and off can cause internal parts to wear out prematurely.
To solve this problem, the most basic approach is to turn off the water supply valve, dismantle the faucet, and replace the O-ring with a new one. However, many households now use modern faucet designs. If it's a faucet with a ceramic cartridge, the entire cartridge might need to be replaced. If you notice your faucet starting to drip, it is highly recommended to arrange for a professional 水喉維修 (plumbing repair) technician to inspect it as soon as possible. Technicians have specialized tools to complete the repair without damaging the faucet's appearance, preventing the situation from worsening.
Common Plumbing Issue 2: Low Water Pressure
Experiencing low water pressure during a shower, where the water flow is reduced to a trickle, is incredibly frustrating, especially in winter when you want a hot shower but the pressure isn't enough to ignite the water heater. There are many causes for low water pressure, the most common being the accumulation of limescale or rust inside the water pipes, which narrows the pipe's diameter. Many older buildings in Hong Kong still use cast iron pipes, where rusting is particularly severe. Additionally, a clogged inlet filter on the water heater or a malfunctioning pressure-reducing valve in the building can directly affect your home's water pressure.
According to the guidelines of the Hong Kong Water Supplies Department, if you suspect a problem with the building's water supply system, you can first inquire with the management office to see if there's a malfunction with the building's water tank or pumps. However, if it's an internal water pressure issue within your unit, it needs to be inspected by a qualified technician. Sometimes, it may require flushing the water pipes or replacing some aging pipes. If the problem involves weak toilet flushing, you might even need 坐廁維修 (toilet repair) to resolve it completely. Professional technicians will use a pressure gauge to measure the actual water pressure and accurately pinpoint the problem.
Common Plumbing Issue 3: Burst Pipe Emergency Handling
A burst pipe is an absolute nightmare for home maintenance! Once a pipe bursts, a large amount of water gushes out, which can not only damage furniture and flooring but also cause electrical short circuits, making it extremely dangerous. Burst pipes usually occur at the joints of aging cast iron or copper pipes, especially when the temperature drops suddenly in winter, as thermal expansion and contraction increase the risk of bursting. Some concealed pipes are buried in walls or underground; if they burst, water will seep out slowly, and by the time it's discovered, severe damage may have already been done.
When encountering a burst pipe, the first thing to do is to stay calm and immediately turn off the main water valve of the unit (usually located near the main entrance or in the kitchen) to cut off the water source. Then, try to clear the accumulated water, move valuable items and appliances away, and contact emergency repair services right away. To prevent such disasters, it is advisable to regularly check exposed water pipes for signs of rust or seepage, and carry out 漏水維修 (leak repair) early on. For concealed pipe leaks, professional teams use advanced equipment like infrared detectors or microwave moisture meters to accurately locate the leak.
Plumbing Maintenance and Care Tips
Prevention is better than cure, and daily maintenance can significantly extend the lifespan of your plumbing. First, do not pour leftover food, grease, or hair down the sink or drain, as this can easily cause blockages. Grease solidifies on the inner walls of the pipes when it cools, building up over time. If you encounter a minor blockage, you can try using a plunger, or pour baking soda and white vinegar followed by hot water. But avoid using strong chemical drain cleaners indiscriminately, as they can corrode the pipes and even produce toxic gases.
If you encounter a severe blockage, such as a 馬桶塞 (clogged toilet) causing flooding, do not attempt to fix it yourself. You should leave it to professional technicians who use high-pressure drain cleaning machines or drain snakes. Below is a simple reference table for common plumbing issues and their solutions:
| Common Issue | Possible Causes | Suggested Solution | Difficulty |
|---|---|---|---|
| Dripping Faucet | Worn O-ring, damaged cartridge | Replace O-ring or cartridge | ⭐⭐ |
| Low Water Pressure | Limescale buildup, clogged filter | Flush pipes, clean filter | ⭐⭐⭐ |
| Pipe Leakage | Loose joints, aging pipes | Reconnect joints, replace pipes | ⭐⭐⭐⭐ |
| Burst Pipe | High water pressure, severe rust | Turn off main valve, emergency repair | ⭐⭐⭐⭐⭐ |
Why Hire Professional Technicians?
Many people try to DIY plumbing repairs to save money. However, plumbing work involves professional knowledge and specialized tools. If not handled properly, it can lead to endless troubles. For example, if the joints are not properly waterproofed, hidden leaks can easily occur. Long-term water seepage can damage the wall structure, cause concrete spalling, and even trigger mold growth, affecting your family's health.
Professional repair teams not only have extensive experience but are also equipped with advanced detection instruments to accurately locate the root cause of the problem. Whether it's a localized repair or a complete repiping as part of a full house renovation, we can provide the most suitable solution. Our technicians are familiar with Hong Kong's building structures and pipe layouts, ensuring the work meets safety standards and gives you peace of mind.
Conclusion and Call to Action
Plumbing issues can range from minor drips to severe burst pipes, and all require timely and correct handling. Remember to regularly check the condition of your home's water pipes. Detecting and repairing problems early can prevent unnecessary losses and hassles. Home maintenance should not be delayed; the earlier you deal with it, the lower the repair costs.

Frequently asked questions
Is it difficult to replace a dripping faucet's O-ring by myself?
If you have basic repair tools and experience, replacing the O-ring of a standard faucet is not too difficult. However, if it's a more complex ceramic cartridge faucet or if the joints are rusted, it's recommended to hire a professional technician to avoid damaging the pipes.
Why did the water pressure in my home suddenly drop?
A sudden drop in water pressure could be due to the building cleaning its water tanks, Water Supplies Department works, or your home's water pipe filters being clogged with debris. You can check with the management office first; if the building's water supply is normal, you'll need a technician to inspect your pipes.
What should I do immediately when a pipe bursts?
When a pipe bursts, the most important thing is to stay calm, locate and turn off the main water valve of your unit immediately (usually near the entrance, kitchen, or bathroom) to cut off the water source. Then, clear the water as soon as possible and WhatsApp 9290 2652 right away to arrange for emergency repair.
