- Mar 19
- 2 min read
A leaking storage water heater is a common issue in Singapore homes. If you notice water dripping from your heater or stains around the unit, it is important to act quickly.
Ignoring the issue can lead to ceiling damage, electrical risks, and higher repair costs.
⸻
• Water dripping from the bottom of the tank
• Rust stains or corrosion
• Ceiling stains below the heater
• Reduced hot water performance
If you notice any of these, your heater may be failing.
⸻
1. Internal Tank Corrosion
Over time, the inner tank can corrode due to constant heating and water exposure.
👉 This is the most common reason
👉 Usually requires full replacement
⸻
2. Faulty Pressure Relief Valve
If pressure builds up inside the tank, the valve may release water.
👉 Sometimes repairable
👉 But may indicate deeper issues
⸻
3. Loose or Damaged Pipe Connections
Leaks may come from inlet/outlet pipes.
👉 Can be repaired
👉 Lower cost compared to tank failure
