Plumbing problems are one of the most common landlord-tenant flashpoints in Singapore. A choked drain might seem minor; a leaking concealed pipe can cause thousands in water damage. Knowing who's responsible — and what to do when things get tricky — can save you money and stress.
The General Rule
Singapore follows a simple principle for most leases:
- Minor, day-to-day plumbing issues: Tenant's responsibility
- Structural or system failures: Landlord's responsibility
- Damage caused by tenant negligence: Tenant's responsibility
The challenge is in the grey areas. Here's how specific issues are typically treated:
---
Issue-by-Issue Breakdown
Choked Drain / Floor Trap
Typically: Tenant's responsibility
Choked drains in kitchens and bathrooms are almost always caused by grease, hair, or debris — i.e., how the unit is being used. A licensed plumber can clear most kitchen or bathroom drain blockages for $60–$120.
Exception: If the choke is in the main building stack (the vertical pipe shared between floors), it's the landlord's (or MCST's) responsibility.
Leaking Tap or Faucet
Typically: Tenant's responsibility (below lease's minor repair threshold)
A dripping tap usually means a worn washer or O-ring — a $30–$60 job for a plumber. Most leases assign minor plumbing repairs below $150–$300 to the tenant. Confirm your TA's threshold.
Toilet Bowl — Choked or Running
Typically: Tenant's responsibility for the choke; split for the cistern
A choked toilet is caused by usage (tenant). A continuously running toilet (phantom flush) is usually a faulty flapper valve in the cistern — cheap to fix ($30–$80) and arguably maintenance rather than fault. In practice, most tenants fix this themselves.
Exception: If the toilet was already faulty at move-in and documented on the inventory list, the landlord should fix it.
Flexible Hose Replacement
Typically: Landlord's responsibility (if it was original to the unit)
Flexible hoses under sinks and toilet cisterns have a lifespan of 5–10 years and can fail suddenly, causing significant water damage. If the hose was original equipment and failed due to age, this is the landlord's responsibility. Proactive landlords replace all flexible hoses between tenancies.
Cost: $40–$80 per hose to replace.
Water Heater — Not Working
Typically: Landlord's responsibility
If the water heater fails and you've done nothing unusual (e.g., didn't tamper with it), this is a landlord cost. Singapore homes use either:
- Electric storage heaters: Larger tank, last 7–12 years; full replacement $300–$600 installed
- Instant heaters: Smaller, wall-mounted, last 5–8 years; replacement $250–$500 installed
Gas water heaters (rarer, mostly in older HDB flats) are serviced differently.
What to do: Notify landlord in writing immediately. If the landlord fails to respond within 3–5 days and you have no hot water, you can arrange the repair yourself and deduct the cost from rent — but document everything.
Concealed Pipe Leak
Typically: Landlord's responsibility — always
Concealed pipes are embedded in walls or under floors. If they leak, it's a structural issue caused by the building or its age — not by tenant use. Signs of a concealed leak include:
- Wet patches on walls that don't dry
- Unexplained increase in water bill
- Bubbling or peeling paint on internal walls
Detecting and repairing a concealed leak is expensive ($500–$3,000+ depending on the extent of hacking required). This is unambiguously the landlord's responsibility. Notify immediately in writing.
Low Water Pressure
Typically: Landlord's responsibility
If water pressure in your unit is consistently low and other units in the building are fine, there may be a blocked or undersized pipe supplying your unit. This is a structural issue for the landlord to fix.
If the whole building has low pressure, contact PUB directly (1800-PUB-SPUB).

What to Do When Your Landlord Won't Respond
Step 1: Notify in writing. Send a WhatsApp or email with photos, clearly describing the issue and requesting a response within 5 working days. Keep copies.
Step 2: Follow up. If no response after 5 days, follow up again in writing. Note that this is your second notice.
Step 3: Get a quote. Obtain a written quote from a licensed plumber.
Step 4: Arrange repair and deduct from rent. If the landlord has not responded or refused to fix a clearly landlord-responsibility issue, you may arrange the repair yourself and deduct the cost from the next month's rent. You must:
- Have notified the landlord in writing at least twice
- Have a written quote or invoice from a licensed contractor
- Deduct only the actual cost, not a premium
Step 5: Small Claims Tribunal. For disputes that cannot be resolved, Singapore's Small Claims Tribunal handles tenancy-related claims. Filing fee is minimal ($10–$20 for claims under $10,000).

Tips for Tenants
- Take a photo and video of all plumbing on move-in day — any pre-existing drips or drainage issues should be documented
- Never pour grease down the kitchen drain — it solidifies and causes chronic blockages
- Use a hair trap in the shower — $2 from IKEA or any hardware store; prevents bathroom drain chokes
- Check under sinks monthly — catch flexible hose bulging or early drips before they become floods
- Know where your water stopcock is — in a flood or burst pipe emergency, turning off the main water supply immediately can prevent catastrophic damage
