Water Heater Leaking

A leaking water heater is one of the most common — and most urgent — issues we handle at FixMyHeater.sg. Whether it’s a slow drip or a full-on flood, water leaks need immediate attention to prevent property damage and electrical hazards.

Types of Water Heater Leaks

Tank Leaks (Storage Heaters)

The most serious type of leak. When a storage heater tank leaks from the bottom:

• Cause: Internal corrosion has eaten through the tank wall
• Can it be repaired? No — a corroded tank must be replaced
• Action: Turn off power and water, call us for same-day replacement

Connection Leaks

Water dripping from where pipes connect to the heater:

• Cause: Loose fittings, worn thread tape, or corroded connectors
• Can it be repaired? Yes — usually a quick, affordable fix
• Action: Call us for same-day repair

Pressure Relief Valve Leaks

Water dripping from the T&P (Temperature and Pressure) relief valve:

• Cause: Excessive water pressure, faulty valve, or overheating
• Can it be repaired? Yes — valve replacement is straightforward
• Action: Don’t ignore this — it could indicate a more serious issue

Casing Leaks (Instant Heaters)

Water appearing from inside the instant heater unit:

• Cause: Cracked internal pipes, corroded heating chamber
• Can it be repaired? Sometimes — depends on the extent of damage
• Action: Have a technician assess whether repair or replacement is better

Preventing Water Heater Leaks

1. Regular maintenance — Annual servicing catches small issues before they become leaks
2. Anode rod replacement — Protects the tank from corrosion (every 2-3 years)
3. Descaling service — Removes mineral build-up that accelerates corrosion
4. Monitor water pressure — Excessive pressure strains connections and valves
5. Replace old units proactively — Don’t wait for a catastrophic tank failure

• 🛑 Turn off water supply — Stop the source of the leak
• ⚡ Cut the power — Switch off the circuit breaker
