Site Findings

A homeowner at The Warren Condominium contacted Homeone after experiencing a Joven Water Heater Rusty issue. Their existing Joven JH35 storage water heater had developed severe internal corrosion, leading to a major leak. Rust-contaminated water had leaked through the unit, causing visible staining and damage to the false ceiling where the heater was installed.

Upon detailed inspection, our technician confirmed that the internal tank had deteriorated beyond repair and the ceiling required cutting to safely remove the faulty unit. In addition, the heater’s connections and mounting showed signs of ageing, making it essential to carry out a full, compliant replacement.

Proposed Solution

Homeone proposed replacing the corroded JH35 unit with a new Joven JSH35 – a modern model with improved reliability and energy efficiency. The replacement included:

  • Careful ceiling cutting to access and remove the damaged unit

  • Reinstatement of the false ceiling after installation

  • New stainless steel piping for the inlet, outlet, and drain within 1 meter

  • Proper re-anchoring of the mounting brackets

  • Installation in accordance with manufacturer’s warranty requirements

  • Full compliance with PUB plumbing regulations, including safety and discharge standards

All works were carried out by our experienced installation team and supervised to ensure technical accuracy and quality workmanship.
