Rheem Water Heater Rusty Replacement: 61SVP10S to EHG-30 at 110A Punggol Field HDB on 5 May 2025

A homeowner at 110A Punggol Field HDB contacted Homeone after spotting reddish stains and water marks spreading beneath their ceiling-mounted heater. Our inspection revealed a severe case of “Rheem Water Heater Rusty”—with extensive corrosion clearly visible around the tank body and mounting ring of the 61SVP10S unit.

From the photos, rust streaks and flaky deposits were leaking from the tank base, indicating that the internal steel tank had corroded through. Brown water discharge, visible on both the bracket and outlet piping, posed an immediate risk of flooding, ceiling collapse, and potential electrical short circuit. Additionally, most of the water pipe fittings were already rusted or leaking at the joints.
