Zheilwane, the installation is similar to the link u provided: http://www.youtube.com/watch?v=DNVlxcF0t3s. except the water pump is diff. i will snap the photo for u by this few days.

U can also drop by my showroom on 23/8 - 27/8/2011 and ask the Grundfos Experts.

just curious...

does anybody that uses pump uses check valve aka no-return valve- single flow valve ?

i know those that pump from well uses it, what about normal home water usage.. ? if im not mistaken if your pump is higher than yr tank then only you require it right ? else no need?

U should use a non return valve for main water bypass but not on ur water pump.

if my tank currently is in my ceiling and i would like to invest in a new bigger water tank that can't sit in the roof
and i put it at ground level, and i dont wan to do a whole re-piping so just attached the new ground tank to the pump at the roof and install a check valve

so that the water won't flow back to the ground level tank.. is that correct , else the pump will be pumping air only lol...

What would happen if ur tank above ur ceiling run out of water first? Would ur pump b sucking some water from the ground tank and also some air from the ceiling tank since it is empty? Not recommended to do such installation as the pump should b installed near to your water tank, if ur tank is at ground floor, it would b hard for the pump to suck in water and booster the water .

sorry if my info was communicated wrongly.. plan to decommission my old tanks in the roof

PLANNING - to get a new 500gallon tank and put it as ground level.. lazy wan redo piping thought can just reattach the new tank outlet to the pump at the roof.. so it will work like pumping from a shallow "well" ...

rather than have to do wiring to place the pump near the new tank and do some kind of shelter for the pump and all

so thinking just put the pump same place and pull a new poly pipe with check-valve, as it will be cheaper and faster to implement

sorry my bad, i think u did mention it b4. Not a good idea also. Just relocate your pump and put it at ground floor, ez job. Not much modifications required.

no worries just wanna seek opinions on the matter... better to ask and learn something new then be an ignorant fool...

true. If u have time, can drop by my showroom and learn more from the real expert (my dad) ahha, i m still learning only

If exisitng water heater is with pump, is that any impact if install water pump?

u can just turn off the heater's pump, nth will go wrong

just curious.. how much on average is a normal pressure gauge to see how much pressure is in our pipe ?

how the sound level be if it ran in? Noisy like hell or ? Electric bill for normal household per day or wil water bill on RM10 per month?

The pump is ard 0.5kW only, if you do not turn on the water, the pump will b in standby mode and would not consume much electricity. Your water heater is 3.6kW while a Grundfos water pump consumes 7times less electricity compared to your instant heater.

Some houses cant hear anything at all while some will have bombing noise. What i can tell u is Grundfos pumps have low noise operation, whether u can hear it or not is depending on how your plumber install it and the structure of your house. If you wan to know more, u can speak to my dad, can learn a lot from him.

Speak to him? Endup my pocket kena $$$ again...hahaha

hahaha, we will have raya promotion from 23-27 August. One of the promotion item is Grundfos + Water Filter package. Grundfos will send their demo truck to our showroom during those few days, u can come and have a look.

Here is the pump that i m using but this model has been discontinued. Grundfos CH-PC model is slightly noisier than this.

Damn noisy...if open water at midnight, for sure I kena bad fire...

watch the whole video, no sound at all...

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.
