Leaky faucets, clogged drains, low water pressure, running toilets, and pipe leaks are the top issues homeowners face — and while some can be fixed with simple DIY methods, others require a licensed plumber.
Singapore’s humid climate, high-rise living, and strict plumbing regulations make proper maintenance especially important. Plumbing works must comply with standards set by the Public Utilities Board (PUB), so knowing when to DIY and when to call a professional matters.
1. Leaky Faucets
A dripping tap might seem minor, but it can waste hundreds of litres of water per year — increasing your PUB water bill.
Common Causes:
- Worn-out rubber washers
- Damaged O-rings
- Faulty cartridges
- Loose internal components
How to Fix It:
✔ Turn off the water supply
✔ Dismantle the tap
✔ Replace the washer or cartridge
✔ Reassemble and test
Replacement parts are inexpensive and available at most hardware shops.
When to Call a Plumber:
- Leak continues after replacing parts
- Corroded internal fittings
- Multiple taps leaking
Ignoring a small drip today can mean a higher utility bill tomorrow.
2. Clogged Drains
Clogged kitchen sinks and bathroom drains are extremely common in Singapore homes.
Common Causes:
- Hair buildup
- Grease accumulation
- Soap scum
- Food particles
DIY Solutions:
✔ Use a plunger
✔ Pour hot water to dissolve grease
✔ Try baking soda + vinegar mixture
✔ Remove and clean drain traps
For deeper blockages, a manual drain snake may help.
When to Call a Plumber:
- Water drains very slowly despite attempts
- Recurring clogs
- Foul smell from pipes
- Multiple drains backing up
Professional plumbers use high-pressure jetting or advanced drain cameras for stubborn cases.
3. Low Water Pressure
Weak water flow from your shower or tap can be frustrating — especially in high-rise flats.
Common Causes:
- Sediment buildup in aerators
- Mineral deposits
- Partially closed valves
- Hidden pipe blockages
Quick Fix:
✔ Remove and clean tap aerators
✔ Soak in vinegar to dissolve mineral deposits
✔ Check main shut-off valve
When It’s Serious:
If low pressure affects the entire unit, the issue may involve the internal piping or main water supply. In such cases, a licensed plumber should inspect the system.
Do not attempt major pipe alterations yourself — plumbing work must meet PUB regulations.
4. Running Toilets
A running toilet can waste hundreds of litres daily — and you may not even notice until your water bill spikes.
Common Causes:
- Worn flapper
- Loose chain
- Faulty float
- Improper tank water level
DIY Fix:
✔ Open the tank lid
✔ Adjust or replace the flapper
✔ Fix the float level
✔ Check the chain alignment
Replacement parts are inexpensive and easy to install.
When to Call a Professional:
- Continuous water leakage
- Internal tank cracks
- Repeated failure after replacement
If unsure, hiring an experienced plumber ensures correct installation and prevents hidden leaks.
5. Pipe Leaks
Pipe leaks are one of the most serious plumbing issues.
In Singapore’s humid climate, unnoticed leaks can quickly lead to:
- Wall damage
- Ceiling stains
- Mold growth
- Structural issues
- Higher water bills
Warning Signs:
- Damp patches on walls
- Bubbling paint
- Musty smell
- Unexplained increase in water bill
Temporary Fix:
✔ Use pipe sealant tape
✔ Apply epoxy putty
✔ Shut off the water supply
But remember — these are only short-term solutions.
Permanent Solution:
Call a licensed plumber immediately. Pipe leaks often require pipe replacement or proper sealing to prevent long-term damage.
When Should You Call a Licensed Plumber in Singapore?
You should contact a PUB-licensed plumber if:
✔ The issue involves concealed pipes
✔ There is risk of flooding
✔ Multiple outlets are affected
✔ Water pressure is extremely low
✔ You suspect pipe bursts
In Singapore, only plumbers approved by the Public Utilities Board are legally allowed to perform certain plumbing works.
Hiring an unlicensed handyman for complex plumbing can result in fines or compliance issues.
Conclusion
Plumbing problems are common in Singapore homes, but not all of them require panic.
Small issues like:
- Replacing washers
- Cleaning aerators
- Adjusting toilet components
can often be handled with basic tools.
However, serious issues like pipe leaks, recurring blockages, or system-wide pressure problems require professional attention.
