Water Heater Rusty: Joven JH56 Replaced with JSH56 at A Landed House at Ban Guan Park on 28 May 2025

A homeowner at Ban Guan Park reached out to Homeone after spotting rust stains around their ceiling and pipework. Upon inspection, our team confirmed a typical case of “Water Heater Rusty.” The existing Joven JH56 storage heater had reached the end of its lifespan, with corrosion visible on the tank body and surrounding fittings.

The water heater rusty condition was advanced enough that active leaks had formed, with rust streaking down from the bottom of the tank. The copper piping and insulation had also started to deteriorate, and several joints were leaking water. Most critically, the installation lacked electrical bonding, violating CP5 safety standards and increasing the risk of an electrical hazard.

Proposed Solution for Water Heater Rusty

To resolve the water heater rusty condition safely and ensure long-term durability, Homeone recommended replacing the unit with the upgraded Joven JSH56—a modern 56L storage heater designed for better corrosion resistance and safety.

Under the supervision of a PUB-licensed plumber, we performed the following:

Removed the water heater rusty JH56 unit, and corroded fittings
Installed the new JSH56 with proper wall anchoring and stainless steel piping
Fitted a drainpipe, double check valve, and stop valve
Upgraded the wiring to include electrical bonding as per CP5
Leak-tested the new system and filed PUB documentation for compliance

All connections and fittings were redone using stainless steel within 1 metre, preventing future rust and improving hygiene.
