Joven Water Heater Replacement at 604A Punggol Road HDB
Joven water heater replacement to restore the hot water, as the existing unit has reached the end of its service life.
Before: Joven JH35
After: Rheem EHG-40
Date Of Replacement: 10 Apr 2025
Project Location: 604A Punggol Road
Before Replacement:
The Rheem water heater replacement at 604A Punggol Road transformed a failing hot‑water system into a fully compliant, energy‑efficient installation. The ageing 35 L Joven unit and corroded pipework provided almost no hot water and violated PUB/BCA regulations by lacking back‑flow protection, a drain line and earth‑bonding, creating risks of rupture, electrical faults and contamination.
After Replacement:
After Homeone completed the Rheem water heater replacement with a 40 L EHG‑40 model, the household now enjoys reliable, rapid hot‑water delivery from a vitreous‑enamel cylinder rated to 0.8 MPa, insulated for superior heat retention and protected by a new PRV, double‑check valve, and electrical bonded pipework. Comprehensive PUB certification ensures full compliance while securing a five‑year tank leak warranty and 1 1-year Rheem EHG 40 Spare Parts warranty by the manufacturer.
Inspection Findings 
- Internal scaling within the heater tank
- PRV inoperative; discharge line absent
- Inlet/outlet plumbing fittings are heavily corroded and seeping
New Components Replaced:
- No double‑check (back‑flow prevention) valve on the cold‑water line
- Missing drain pipe for temperature–pressure relief
- Absence of protective earth‑bonding to metallic pipework
Our PUB Licensed Plumber has endorsed that work is done in accordance with the conditions stated below:
- All water service installations must be in accordance with the Public Utilities (Water Supply) Regulations, Singapore Standards 636 for Water Services, and all other relevant statutory requirements.
- The proposed works shall not adversely affect the existing water supply reticulation system.
- The proposed water storage heater is installed in accordance with the specifications and requirements of the manufacturer.
- The installation of double-check valves is safe and effective in preventing backflow and the back-siphonage of water from the storage water heater through the heater inlet pipe, and will be safe for use.
Conclusion:
In conclusion, the newly installed Rheem EHG‑40 system fully complies with all current PUB regulations and was carried out under the direct supervision of our team of Licensed PUB Plumbers, ensuring safety, reliability, and lasting performance.
