Replacement of a Rheem 23L Vertical storage heaters at a Hougang St 51 HDB.


It is a very old 81VP6S 6-gallon model that has been there around 20 years.


Owner wants the same model, we provided the latest replacement model a Rheem 85VP6S, 23L.

All pipe works connecting to the heaters are replaced with stainless steel from original copper. We employed the Anti-Vacuum at the inlet placed at least 75mm above the top of the tank. A new approved stop and double check valves are employed in accordance with the manufacturer’s specification. Such will comply with PUB.

Our PUB Licensed Plumber has supervised and approved the installation.

There is a 1-year warranty by Homeone for this installation on top of the warranty provided by Rheem.
