Rheem Water Heater Corrosion Replacement: 85VP6S to 85VP6S at Seletar Hills Estate on 5 Apr 2025

A homeowner at Seletar Hills Estate contacted Homeone after experiencing performance issues and visible leaks from their Rheem 85VP6S storage water heater. The unit exhibited signs of severe corrosion at the tank body and had begun leaking, clearly indicating internal damage beyond repair and reaching the end of its operational lifespan.

Our team conducted a detailed on-site assessment and confirmed that the existing heater was no longer serviceable. Furthermore, there was no electrical bonding installed, posing a serious electrocution risk and violating Clause 413-02 of the Singapore Standard CP5:1998.

Homeone recommended a like-for-like replacement with a new Rheem 85VP6S heater, ensuring a proper and safe installation with full PUB and CP5 compliance, including the addition of equipotential bonding and a new wiring setup where needed.

Site Findings

A homeowner in Seletar Hills reported water leakage and heating failure from their existing Rheem storage water heater. Upon inspection, Homeone’s technician identified widespread corrosion along the tank body, with visible rust lines and active leakage, indicating an internal tank breach.

Additionally, the original setup lacked protective equipotential bonding, a vital safety feature to prevent electric shock, especially in wet environments. This omission placed the installation in violation of Singapore Standard CP5:1998 Clause 413-02, making immediate corrective action necessary.

Proposed Solution

Homeone recommended a direct replacement using the same model—Rheem 85VP6S—to maintain the homeowner’s preferred tank capacity and installation footprint. In addition, our team ensured the following enhancements:

  • Installed new protective earth bonding to comply with electrical safety standards

  • Verified existing pipework and fittings for compatibility

  • Recommissioned the system under licensed supervision

All work was carried out by a PUB-licensed plumber and EMA-licensed electrician, with documentation submitted upon completion for compliance records.
