Common HDB Home Maintenance Issues & What to Do
Problem: Water heater trips the circuit breaker
Cause: Earth leakage in the heater, or the circuit is overloaded. Solution: Do not reset the breaker repeatedly — call AOT to inspect. This could indicate a serious electrical fault in the heater.
Problem: Low water pressure in bathroom
Cause: Partially closed gate valve, blocked aerator on the tap, or a failing water pump. Solution: AOT will diagnose the root cause and fix it properly rather than applying a temporary workaround.
Problem: Aircon dripping water inside the room
Cause: Blocked condensate drain line (most common in Singapore) or dirty air filter restricting airflow. Solution: A standard aircon service or drain pipe flush usually fixes this. Contact AOT for a same-day visit.
Problem: Toilet flush keeps running
Cause: Faulty fill valve or flush valve. A constantly running toilet wastes thousands of litres of water per month. Solution: AOT replaces the faulty component at a reasonable fixed price.
Problem: Circuit breaker keeps tripping
Cause: Overloaded circuit, faulty appliance, or deteriorated wiring. Solution: AOT's electricians will identify the fault and either replace the MCB, add a new circuit, or repair the wiring as needed.

- 🔧 Replace tap washers annually before they become dripping leaks
- 💧 Check under sinks and basins for slow leaks that can rot cabinet floors over time

Do I need HDB approval for home maintenance works?
Routine maintenance (replacing water heaters, repairing taps, servicing aircons, replacing sockets) does not require HDB approval. Major renovation works (hacking walls, changing floor tiles, etc.) require HDB's Renovation Permit. AOT advises on what is permissible and what requires a permit.
