hi, i want to install pump to my house too. I understand that the water pump will be installed after my water tank, so does this mean my kitchen water (which is from main water supply) will not have the water pressure from the pump?? My main water pressure is not very strong too actually, so will take time for my water tank to fill up.

Option 1 : Add 1 tank at ground flood and install a pump here as well, this will boost your kitchen pressure and fill up the tank above faster.
Disadvantage : Waste space and extra pump $$.

Option 2 : Do an external piping from the pump sbove your roof to your kitchen.
Disadvantage : Some customers think it is not hygienic . .

We are having SALES for Grundfos in-conjunction with our POST-EXHIBITION SALES on 14 and 15 Oct (2 days only). We are not allowed to quote prices online and through phone, offer price is only for walk-in customers.

doesn't need waterpump? incoming water pressure good? new area?

PM me what u mean. Tks

just read online about Scala2, what is the price for it?

any idea?

it is like a all for 1 pump, negative suction, main suction and etc etc. For standard installation, install next to water tank, actually there is no need for scala2, the regular CM-PM is already sufficient.

hi there.. do you do grundfos uni-e cm5-4 pump setting and installation? if yes please pm and we can discuss. thanks.

dont need setting, all pre-set already. This is an expensive pump, do get some1 professional to install if not will be wasted bro

I dont know if this is the correct thread..but i would like to ask, is it safe to use a booster pump?..since mostly i notice comes without ELCB if im not mistaken, unlike our bathroom water heater..feels like very dangerous..what will happen if the motor comes in contact with the water if the seal inside start to leak?..

dont think it's allen wrench.
i just tried to adjust mine. seemed to be pentagon shaped instead of hex.
will try take a picture.

Problem is, who can we contact to get it adjusted the properly?

It is Allen key. But in inch size.

ozak any idea what size is it?
i need to take picture, but mine is installed upside down so bit hard.

I don't remember anymore.

I don't have the inch size allen key too. So I use mm size to poke into it. The allen key slighty bigger size. I knock it in and turn.

I have a set of allen key. So just try the 1 best fit.

But strange is, the syabas dismantle it away when they repair the broken pipe. Now my piping without that valve anymore.

But why going to adjust it? That valve is either open or close. Not adjust for slow or fast flow.

I noticed the UNI-E models also have a pressure tank. If we don't want this maintenance issue (pump air once a year) but yet want the VSD feature, can we order UNI-E without the tank?

nope cant do so. Actually even i m only using CM 5-4pm1, dont wanna maintenance, so far so good, dont really need the VSD

unless big houses with lots of bathrooms then UNI E is the best choice

Hi, My new house 2 half storey semi d c/w solar from developer.

1bathroom lvl 2
3 bathroom lvl 1
1 bathroom lvl g

All running water from tangki above lvl 2. Most of my friend told me solar will have pump but i checked mine is without. So thinking to install a grundfos pump for 2 rainshower n 2 normal shower. How many HPs should i install?

And direct water pressure should be around 2-3bar .should i also install a pump outside ?

Haha good one. I think all will be using from tangki instead of direct. Just need info of how many HPs to use as i heard too high HPs will cause hose to crack n can't last long.

This is something that i have to learn then... will try to talk to the contractor bout it.
