Rheem Water Heater Rusty Replacement: Rheem Vertical 30L to 85VP30S at A Landed House at Seletar Hills Estate on 27 May 2025

A homeowner at Seletar Hills Estate contacted Homeone after noticing advanced rust on their ceiling-mounted Rheem water heater. Upon inspection, our technician confirmed a serious case of "Rheem Water Heater Rusty"—with rust visibly spreading across the tank body, pipe fittings, and outlet piping.

The condition of the water heater presented several risks. Rust streaks were evident along the base and side of the tank, clearly indicating internal corrosion had begun breaching the tank wall. Brownish-red water residue was found dripping onto the heater bracket and adjacent surfaces. The hot, cold, and drain piping were all visibly affected, with joint areas showing signs of oxidation and possible leak points.

Continued use of this Rheem Water Heater Rusty unit would eventually result in a full tank failure, leading to water damage, ceiling collapse, or worse—an electrical short circuit. The homeowner, aware of these risks, provided a new Rheem 85VP30S unit for installation and requested to retain the vertical 30L design due to space and capacity needs.
