Heater leaking? Let's stop it.
Dripping, pooling, water-stained ceiling downstairs? Most leaks are valve-level — under $150 to fix. We diagnose on site within an hour and tell you honestly whether it's a 30-minute repair or a same-day replacement.
Four places it usually starts.
Knowing where helps us tell you fast: repair or replace. Snap a photo of the wet spot and send it on WhatsApp.
The temperature & pressure valve releases water when internal pressure rises too high. Constant dripping = either the valve is faulty (cheap fix) or the tank pressure is genuinely too high (expansion-tank or thermostat issue). Easy to diagnose, usually $80–140.
Where the cold-water inlet or hot-water outlet pipe connects to the tank. Loose fitting, corroded brass, or worn PTFE tape causes a slow seep. Resealed + retightened in 30 minutes if caught early.
The valve used for descaling. Drips when the seal degrades, or after a clumsy descale that didn't reseat. Replacement valve + new washer — $80–120.
Water seeping or weeping from the actual tank wall = the inner lining has corroded through. No repair will save it — once water finds a path through the steel, only replacement makes the leak go away. Storage tanks last 7–10 years in Singapore.
A drip today is a flood next week.
A 10ml/min drip is 14 litres a day. Behind cabinetry or above a downstairs neighbour, that's mould, swollen wood, and an HDB complaint within the week.
Water + 230V is a shock hazard. The RCD usually catches it but a slow seep through insulation can degrade before the RCD trips. Don't run the heater while leaking from the body.
Most leaks are valve-level, not tank-level — and at the valve stage they're a $100 fix. Wait too long and the same problem becomes a $700 replacement.
