Common Water Heater Problems
Rusty or Brown Water
Internal tank corrosion or rusty inlet/outlet pipes.
Rusty Stop Cock & Fittings
Even small leaks create constant moisture, promoting rust and mineral build-up.
Leaking Water Heater
Leaking water can damage flooring, cabinets, and nearby walls, leading to costly repairs.
Missing the drainpipe
Storage water heater pressure relief valve missing drainpipe – a PUB safety non-compliance
Thermostat cable burnt
A burnt thermostat cable is a common electrical fault in storage water heaters. It usually occurs when the wire insulation deteriorates due to prolonged heat exposure, loose wiring connections, or electrical overloading.
High Water Pressure
140 PSI water pressure is in violation of SS 636:2018 – Code of Practice for Water Services, Clause 6.7. According to the standard:
In tall buildings, fittings should not be subjected to pressures greater than 35 metres head, which is approximately 50 PSI
Unsafe unlicensed installation
- A sudden power trip is one of the most common warning signs of a failing water heater or an unsafe installation.
- When your water heater trips the circuit breaker or RCCB (as shown in the photo), it usually means there’s electrical leakage or short-circuiting inside the unit. This is often caused by:
- Rust or corrosion in the tank allowing water to reach live electrical components
- Burnt heating element or thermostat due to overheating or lack of maintenance
- Loose or exposed wiring from improper installation (often by unlicensed contractors)
- Lack of RCCB testing – risking electric shock and fire hazards
