At Homejourney, we prioritize your safety and peace of mind by connecting you with verified plumbers who offer transparent pricing and quality workmanship.
This guide covers the most prevalent plumbing problems in Singapore homes, realistic cost expectations, and practical solutions to help you address issues before they become expensive emergencies.
The Most Common Plumbing Problems in Singapore
1. Leaking Taps and Pipes
What it is: A slow drip from a tap or pipe may seem minor, but it wastes significant water over time and increases your water bill considerably.[1] Leaks are typically caused by worn-out washers, corroded pipe joints, or deteriorating seals.
Why it happens: In older HDB flats and condos, corrosion from age and water quality is a primary culprit. Worn washers are common in high-use taps like kitchen and bathroom faucets.[1]
Cost to fix: Simple washer replacement typically costs SGD 50-150, while more complex pipe repairs or cartridge replacements range from SGD 150-400. Emergency call-outs (after hours or weekends) may incur additional charges of SGD 50-100.
Prevention tip: Have your taps and pipes inspected annually, especially if you live in a property over 15 years old. Replacing worn washers early prevents full-blown leaks that could damage walls and floors.[1]
2. Clogged Drains and Sink Chokes
What it is: Hair, soap residue, food waste, and mineral buildup cause drains to slow or stop completely.[1][2] This is one of the most frequent issues Singapore homeowners encounter.
Why it happens: Kitchen sinks accumulate grease and food particles, while bathroom drains collect hair and soap scum. In Singapore's hard water conditions, mineral deposits can also contribute to blockages.[2]
Cost to fix: Basic drain clearing with a plunger or simple tools costs SGD 80-150. Professional drain cleaning using a drain snake runs SGD 150-300. For stubborn blockages requiring hydro-jetting or pipe inspection, expect SGD 300-600. Chemical drain cleaners (DIY) cost SGD 20-50 but may damage pipes.
Prevention tip: Use drain strainers in all sinks and showers, avoid pouring grease down drains, and clean aerators regularly.[1] For persistent issues, engage a professional plumber rather than risking pipe damage with harsh chemicals.
3. Toilet Problems (Running, Leaking, Weak Flush)
What it is: Toilet issues include constant running (water flowing into the bowl), leaks around the base, and weak flushing.[1][2] A running toilet alone can waste up to 200 gallons of water daily.
Why it happens: Faulty flapper valves, malfunctioning fill valves, worn wax rings, or damaged flush mechanisms cause these problems.[2] Flushing inappropriate items (wet wipes, tissues, sanitary products) exacerbates issues.
Cost to fix: Flapper valve or fill valve replacement costs SGD 100-250. Wax ring replacement (for leaks around the base) ranges from SGD 200-400. Full toilet replacement, if necessary, costs SGD 400-800 for standard models. Minor adjustments may be free if covered under warranty.
Prevention tip: Avoid flushing anything except toilet paper and human waste.[1] Have toilets inspected annually and address leaks immediately to prevent water damage and mold growth in bathrooms.
4. Low Water Pressure
What it is: Weak water flow from taps, showers, or both indicates low water pressure—a frustrating issue that affects daily routines.[1][2]
Why it happens: Sediment buildup in pipes, clogged aerators, faulty pressure regulators, or issues with the main water supply line cause low pressure.[2] Mineral deposits are particularly common in Singapore due to water hardness.
Cost to fix: Cleaning aerators costs SGD 30-80 (often free if you do it yourself). Pressure regulator adjustment or replacement ranges from SGD 150-350. If the issue is widespread (affecting neighbors too), it may be a PUB water supply issue requiring no cost. Pipe descaling for mineral buildup costs SGD 200-500.
Prevention tip: Clean faucet aerators quarterly. Check with neighbors to determine if the problem is isolated to your unit or building-wide. If isolated, consult a plumber to identify whether it's a supply line issue or internal pipe problem.[1]
5. Water Heater Issues
What it is: Problems include inconsistent water temperature, unusual noises, water leaks around the unit, or complete failure to heat water.[1][3]
Why it happens: Faulty thermostats, failing heating elements, corroded pressure valves, or sediment accumulation cause these issues. Most water heaters in Singapore last 8-12 years before major problems develop.
Cost to fix: Thermostat or pressure valve replacement costs SGD 150-300. Heating element replacement ranges from SGD 250-450. Annual servicing (recommended) costs SGD 80-150. Full water heater replacement costs SGD 800-2,000 depending on capacity and type.
Prevention tip: Schedule annual servicing to extend your water heater's lifespan and prevent sudden failures.[1] Flushing the tank annually removes sediment buildup, improving efficiency.
Understanding Plumbing Costs in Singapore
What Affects Plumbing Prices
Several factors influence the final cost of plumbing repairs in Singapore:
- Complexity of the problem: Simple fixes (washer replacement) cost less than complex issues (pipe replacement or water heater repair).
- Accessibility: Pipes hidden behind walls or under floors require more labor, increasing costs.
- Emergency vs. scheduled service: After-hours, weekend, or same-day emergency calls typically cost 30-50% more.
- Property type: HDB flats may have different plumbing configurations than condos or landed properties, affecting repair complexity.
- Materials needed: Premium pipes, fittings, or fixtures cost more than standard alternatives.
- Plumber experience: Licensed, experienced plumbers charge more but offer better warranties and reliability.
Typical Service Call Charges
Most plumbers in Singapore charge a service call fee (SGD 50-100) to diagnose the problem, which is often waived if you proceed with repairs. Labor rates typically range from SGD 60-100 per hour, with most jobs taking 1-3 hours. For transparent pricing without hidden charges, use Homejourney to compare quotes from verified plumbers in your area.
DIY vs. Professional Solutions
When to DIY
Minor issues you can safely handle yourself include cleaning aerators, using a plunger on simple clogs, and replacing tap washers (if you're mechanically inclined). These tasks save money and can be completed in minutes to an hour.
When to Call a Professional
Contact a licensed plumber for leaking pipes, persistent clogs, toilet repairs, water heater issues, or any problem affecting multiple fixtures. Attempting complex repairs yourself risks causing additional damage that becomes far more expensive to fix. Professional plumbers carry insurance, offer warranties on work, and ensure repairs comply with Singapore's building codes.
Preventing Costly Plumbing Emergencies
Regular maintenance is significantly cheaper than emergency repairs. Annual inspections (SGD 80-150) can identify worn washers, corrosion, or pressure issues before they become major problems. Simple preventive measures—using drain strainers, avoiding grease in drains, not flushing inappropriate items, and servicing water heaters—extend the life of your plumbing system and reduce unexpected costs.
Many homeowners in Singapore discover plumbing issues during property viewings or after moving in. If you're purchasing or renting a property, have a plumber inspect the system as part of your due diligence. This identifies potential issues before you're responsible for repairs.

Frequently Asked Questions
How much does a plumber cost in Singapore?
Service call fees typically range from SGD 50-100 (often waived with repairs), while labor costs SGD 60-100 per hour. Actual repair costs vary widely—simple fixes like washer replacement cost SGD 50-150, while complex repairs like pipe replacement or water heater installation can exceed SGD 1,000. Use Homejourney to get transparent quotes tailored to your specific problem.
What's the difference between a general plumber and a specialist?
General plumbers handle routine repairs like tap fixes, drain clearing, and toilet repairs. Specialists focus on specific areas—gas plumbers for gas line work, water heater technicians for heating systems, or drainage experts for complex blockages. Specialists typically charge more but offer deeper expertise for complicated issues.
Can I claim plumbing repairs under insurance or warranty?
Most homeowners' insurance covers sudden, accidental damage (like a burst pipe) but not wear-and-tear repairs. New properties may have builder warranties covering defects. Check your policy and warranty documents. For rental properties, landlords typically cover structural plumbing issues while tenants handle minor maintenance.
Is it cheaper to fix or replace a water heater?
If your water heater is under 8 years old and the repair costs less than 50% of replacement, repair is usually worthwhile. For units over 12 years old or requiring expensive repairs (over SGD 500), replacement is often more economical in the long run due to improved efficiency.
How do I know if I need emergency plumbing services?
Seek emergency services for burst pipes, major leaks causing water damage, sewage backups, or complete loss of water supply. These issues require immediate attention to prevent property damage and health hazards. Emergency calls cost 30-50% more than scheduled services but are essential in urgent situations.
