Common Water Heater Problems
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.
Rusty Stop Cock & Fittings
Over time, the stop cock and pipe fittings connected to a water heater can suffer from rust and corrosion due to constant contact with moisture and heated water.
Leaking Water Heater tank
In older HDBs (built before 2010).
Missing the drainpipe
Storage water heater pressure relief valve missing drainpipe – a PUB safety non-compliance
RCCB tripping during shower
Caused by failing heating element.
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
- An inner tank leak is one of the clearest signs that your water heater has reached the end of its service life.
-
Corrosion over time – The tank’s enamel lining has worn off, exposing the steel to rust and water damage
- High water pressure – Excessive mains pressure puts stress on the tank walls, causing cracks and leaks
- Drain Pipe Choked
- To ensure compliance and protect your family’s health, always engage a PUB Licensed Plumber for installation and replacement works.
