Common Water Heater Problems

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).

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

RCCB tripping during shower
Caused by failing heating element.
