8 Most Common Toilet Problems and Fixes
Here's a breakdown of frequent issues in Singapore homes, with quick diagnostics and solutions grounded in real cases.
1. Running Toilet (Phantom Flushing)
A running toilet stems from a faulty flapper valve, causing continuous water flow and higher PUB bills.[1][2] In HDBs, this wastes 200L daily.
Quick Fix: Lift tank lid, check flapper seal. Replace if warped (S$10-20 part). Adjust chain for proper closure.[1][3]
2. Toilet Not Flushing or Weak Flush
Toilet not flushing often results from low tank water, clogged rim holes, or flush valve issues.[1][2][5] Common in older HDB units with mineral buildup.
Quick Fix: Clean rim holes with brush and vinegar. Adjust water level or replace flush button (S$15).[3][5]
3. Clogged Toilet (Bowl Choke)
Excess toilet paper or wipes cause overflows, risking HDB floor damage.[1][2][4] Singapore's narrow pipes exacerbate this.
Quick Fix: Plunge vigorously. For stubborn clogs, use toilet auger. Avoid chemical cleaners long-term to protect pipes.[4]
4. Toilet Leak
Toilet leak from wax ring, loose bolts, or cracks leads to mold in humid Singapore bathrooms.[1][5] Check base for water.
Quick Fix: Tighten bolts. Replace wax ring (DIY possible, S$20). Dye test: Add food coloring to tank; if it seeps to bowl, replace flapper.[5]
5. Slow-Filling Tank
Sediment in fill valve or closed supply valve delays refills.[1][2] Prevalent in areas with hard water like Jurong.
Quick Fix: Fully open valve. Clean/replace fill valve (S$30).[1]
6. Unstable/Wobbly Toilet
Loose bolts or uneven HDB floors cause rocking, a safety risk.[1] Condo tiles may crack.
Quick Fix: Tighten bolts; use shims for leveling.[1][3]
7. Stuck Flush Button/Handle
Sunken or loose buttons in dual-flush systems fail due to wear.[3] Common in 10+ year HDB toilets.
Quick Fix: Lubricate or replace mechanism (S$25).[3]
8. Incomplete Flush or Double Flushing
Chain misalignment or partial clogs require adjustments.[3][5]
Quick Fix: Adjust flapper chain; clean jets.[3]

HDB vs Condo Toilet Repair Specifics
HDB toilets use standardized Geberit systems; repairs must follow HDB guidelines to avoid voiding warranties. Condos often have MCST rules for shared plumbing.
In HDBs like Punggol, narrow chokes are common due to vertical stacks—use hydro jetting professionally.[4] Condos in Orchard may need licensed plumbers for luxury fixtures.
Homejourney tailors services: HDB quick-fixes under S$60, condo full WC replacements S$250+ with MCST approvals.
