Ok Thanks your infomation.

i haven't buy yet. I saw in the CT Hardware promotion catalog sells at RM 1650 including installation BUT not sure the price is including the pump house or not of course better call them to clarify. And another offer from Megaseven is RM 1768 including the pump house, detector in the water storage tank in order to avoid pump operate dry run.

I also heard from some dealer said Gemini is under Grundfos and It made in Europe BUT Grundfos pump is made in China and yet the Gemini is cheaper.

If u manage to find better deal than above do let me kno

Ok no problem.

try see Tsunami Pump .. http://csp.my/tsunami-pump.html .. This is a very good product pumps.. i have installed it.. Take the Stainless steel pump .. Pump with installation about RM 1340 .. non Stainless steel cheaper by RM40..

You guys put your pump at ground floor from water meter to pump into house?
Or put at roof to pump from tangki to downstairs toilets?

What Grundfos model is reasonable for small double storey house?

I put mine after tank going to toilets. If you put at water meter no use it just pushes water up to you tank but teh distribution to toilets no pressure.

I am using CM3 5PT as I like the tank on the top concept so as not to overwork the pump but yearly maintenance must pump air into tank. However the CM3-5PM1 also should be ok.

Cannot put pump after the meter, what i know this is illegal, need to be after a storage tank.

TQ for response.

Those pump with a tank on top must pump air into it once a year as maintenance?

Yup you can do it yourself with bicycle pump but i plan to sigh a yearly contract with Grundfos who will sned a guy over and service and maintain. For the first 5-6 years no problems. Then on and off small things like the relay etc etc may need to be changed but so far touch wood with my old unit no major problems.

Just going to sign contract fro new unit in another house.

TQ bro for response..

I was wondering, let say our toilet has some minor leak (which is quite common as we normally will notice some water flow into toilet bowl continuously). With this leak, the pump at the roof will start/stop often lor, correct.

Correct i use this as a mechanism to check if there are leaks and rectify the leak.
Sometimes i am sitting in my house and suddenly the pump goes off i know there is a leak somewhere or i left one of the bathroom taps on.

TQ bro.
Can hear the pump cut in even it is installed at roof top?
CM3-3PT comes with a big tank, CM3-5PM1 without tank, wonder which is better leh?

Can hear but my CM3 5PT is quite quiet compared to my older unit.
Hahaha as to which is better you have to use your judgement bro I cannot help you with that one

The tank on 3PT is smaller than the one in 5PT i think. But you can judge. Everytime you flush you can hear the pump if CM3 and CM5 may take a flush and a wash of the hands to trigger

Pump with compressed air is good for users that switch on 24x7.

I have a habit of switching off the Pump power before leaving the house for long hours (e.g. work, holiday or shopping) and open the tap for few second to release the pressure of the water. This method allow me to have a more reliable flexi hose (e.g.) at bidet and behind the WC connector.

Before this, I left the pump on 24x7, and every year one or two flexi hose will leak due to the pressure. Now that I practice this habit, never have any issue on the flexi hose.

Therefore having a pump with compress air storage will not suite the pattern I practice.

With tank one is without dry cut off safety.
The CM3-5PM1 without tank, but have dry cut off safety. I pun dunno which is more important, higher pressure with dry cut off or lower pressure without dry cut off......... pening.....

Bro I think both have run dry protection but not sure ......
Just confirmed bro those with tank no dry run protection

Nmind, when run dry, just off it lor

Anyone use Hitachi water pump?
Is it reliable?

Quick question. is the vibration mat compulsory if i install Grundfos pump?

From wht i hear no but it will reduce sound from vibration significantly. Worth the investment
