A homeowner at 747 Woodlands Circle HDB reached out to Homeone after noticing signs of corrosion and water seepage from their Ariston AN 30 R storage water heater. The unit had visibly rusted and showed clear evidence of internal deterioration, indicating the end of its service life.
Upon inspection, our team confirmed multiple compliance issues: no double check valve to prevent backflow contamination, no drain pipe to discharge relief water safely, and no electrical bonding for electrocution protection. In addition, the heater had been wired using an undersized 1.5mm² cable, which does not meet the electrical requirements for such appliances.
We proposed a fully PUB-compliant upgrade using a modern Ariston AN2 30 RS unit, paired with a new 2.5mm² cable, proper bonding, and all required safety fittings to restore peace of mind and system integrity.

A homeowner at 747 Woodlands Circle HDB reported signs of corrosion and suspected leakage from their water heater. Upon arrival, our technician discovered extensive rust on the Ariston AN 30 R unit, along with signs of water leakage at the tank base—an unmistakable indicator of internal corrosion and tank failure.
Our assessment uncovered several safety and compliance breaches:
Missing double check valve, increasing risk of water supply contamination.
No drain pipe on the temperature relief outlet, breaching SS636.
Underrated 1.5mm² wiring, below the minimum safety requirement for water heaters.
The unit had clearly reached the end of its usable life and required immediate replacement with all missing safety measures addressed.
To ensure long-term performance and full regulatory compliance, Homeone recommended replacing the corroded Ariston AN 30 R with a brand new Ariston AN2 30 RS water heater, featuring advanced insulation and a reinforced tank design.
To restore safe operation, we:
Installed a double check valve to prevent backflow.
Fitted a drain pipe to discharge relief water safely.
Upgraded to 2.5mm² wiring and added electrical bonding.
Used stainless steel pipes for inlet and outlet connections (within 1 meter).
All works were carried out under the supervision of a PUB-licensed plumber and EMA-trained electrician.
Isolated electrical and water supplies
Assessed heater elevation relative to the drain
Evaluated structural conditions and wall bracket stability
