Rheem Water Heater Corrosion: EHG-60 Replaced with EHG-40 at Jade Residences on 9 Jul 2025

A homeowner at Jade Residences contacted Homeone after repeated electrical tripping caused by their Rheem EHG-60 storage water heater. The unit was frequently non-functional and posed an ongoing inconvenience. Our technician conducted a thorough site assessment and discovered a severe case of Rheem water heater corrosion—the internal tank was leaking, and visible signs of rust were present around the heating element and fittings. As the heater had reached the end of its service life, the only safe and reliable option was full replacement.

The customer opted to downsize to a Rheem EHG-40, which was sufficient for their updated household usage needs. We proceeded with a full PUB-compliant installation, resolving not only the corrosion issue but also correcting multiple safety non-compliances found in the original setup.
