This is the high level water supply plan for my new 2-storey home in Johor Bahru. Appreciate if any one of you could have a look and comment.

I have also contacted zheilwane to ask for his associates or friends in JB who is familiar with the Grundfos pump and could help me with the installation.

Hi zheilwane

That has helped clarified a lot. I did not expect you to make correction on the diagram. Thank you for going the extra mile to help.

I have not purchased the pump. Grundfos Malaysia directed me to a Johor Bahru dealer (Dataran Tenaga). In a brief phone enquiry I found out the company apparently does not provide installation service. They are saying most plumber would be able to carry out the installation. I need to check this out further when I visit them in person.

Added on October 2, 2011, 9:49 amThe Grundfos CMB 3-5 comes with integrated non-return valve. By that I presume in the event of power failure to the pump, the direct water bypass would not be able flow from pump outlet to pump inlet and subsequently flood the roof top tank. Is my understanding correct?

Hi zheilwane, by going the extra mile you made an impression. That impression is likely to last. With you around I think the company is on the right path.
