I am looking for water pump for my double storey house. What is the range and price like?
Can recommend. I'm at PJ area.

ask the ZEIN at this forum.

I'm using a Grundfos pump for my house. It's a CH2-50PC model, cost me slightly more than 1.2k
The model is the same as in the following link.

Grundfos Pump

Hope that helps.

Grundfos is the leading brand.

I would not advise you to go for pump.
I'd suggest you to get the "direct water" from water meter.

if the direct water pressure to low then how ?

why you advise not to go for pump? cause the pressure caused your old pipes/joints to leak ?

Unlikely. Direct water pressure is pretty high.
The pressure is good enough to deliver the water from reservoir to your house.

I suggested direct water because it's cheaper.
Electricity free. Maintenance free.
For my house (a semi-D), it only cost me MYR600 (labor and & material).
The water pressure is very high (even it passthrough an outdoor Diamond master filter).
No regrets since day 1.
The "tangki water" will be automatically triggered when there is water rationing.
I only use "direct water" for the shower heads.

good for you.. cause mine is like shit..

i got the same grundfos pump CH2-50PC, for about RM1.2k.

yes i did have some leak at the tangki and toilet sink incoming joints, but these can be spotted easily when u run the pump for a day or two. then just need to rectify.

so far, pressure has been really strong, all my shower heaters are without built in pumps, and yet shower pressure is excellent! by the way, i have 5 toilets in the house, and even with ALL of the taps running, pressure is still good

your water tank before your pump how big ?

Taiko, wrong spelling it should b zean haha. I guess most of the forumers here are using Grundfos CH2-50PC. THe pressure is strong and very durable

Added on September 26, 2011, 8:03 pmIs ur house a new area? After 3-4 years, u might change ur mind...

The direct water might b strong now but few years later when the gov pipes got clogged or when ur neighbours start to use water together, the pressure will become weak. When the water pressure becomes weak, u nd to add a pump but after few years only adding a pump, you will have some headache as u nd 2 prepare the wiring, redo the piping and might have some place leaking. If u install a pump now when u r renovating ur house, u will save the headache in the future.

Moreover, if there is water rationing, how are you going to shower?

+1 Grundfos

taiko, don't worry... everybody here knows who you are... no worries

zheilwane, mine is new house. going renovate this week (fastest).
if i bought grundfos pump CH2-50PC from you, what are the cost?
1.2k include installation (everything). do i need to ask wireman to drag wire to the tangki. or u need to send someone to see see my tangki or environment 1st. see whether can install Grundfos or not.

when i install Grundfos, all of my paip will be strong even direct link from water meter?

I don rmb quoting u RM 1.2k with installation...definitely u can install a water pump, dont nd to check. Few things to do

1) Prepare a switch for the pump and drag it near to the tank's outlet, then prepare a socket point there for the pump to plug in.
2) If it is outdoor, prepare a shelter for the pump as it is not water proof.
3) Make sure that the pipes are connected to your water tank and not direct water. (If new house, it is connected to water tank but 2nd hand, may b the previous owner modify it to direct water)

hi zheilwane, the price is based from Serofax.
actually what is the actual cost + installation?
i don understand your item 3. the pipe means ? no idea where the pipe suddenly come from.

3) Make sure that the pipes are connected to your water tank and not direct water. (If new house, it is connected to water tank but 2nd hand, may b the previous owner modify it to direct water)

-- direct water - pump connected directly from the government main water pipe - No No
-- water tank - pump connected from the water tank - Yes Yes

Hi bro, sorry to bring up the old thread.

May I know why NO NO water pump direct connect from gov main water pipe? It can spoil the pump when pump stop running? Thanks.

Illegal if i remember correctly.

Hi,
How much is the installation for the Pump? Say for grunfos pump.
I am also intended to get a heater tank... how much is the installation and how they charge the copper piping???

According to SPAN guidelines, all tappings from service pipe other than the pipes to kitchen sinks shall only be channeled to storage / break cistern to avoid contamination in the main pipelines.
Pumping system is only allowed at the downstream of storage cistern.

I did that last time but now regret. The pressure getting low after my neighbor moved in. Now i have to instal pump already. Luckly i have prepare a power point last time when i did my reno. Bought grundfos from zean. Very good. Very quite.

yeah, most contractors will recommend u to use direct. It is a waste of money for long term as u will have issue later.

At first u pay few hundred to modify to direct. Later when pressure is weak, u need to spend another few hundred to modify it back to the original piping, isnt it waste of money?

Added on August 31, 2012, 6:49 pm2molo (1st September) will b the last day of our MERDEKA SALES. YOu guys might wanna drop by to enjoy the great discounts

This post has been edited by zheilwane: Aug 31 2012, 06:49 PM

It is almost a year since I posted that message.
My water pressure is still very strong until this very day.

Complete silent + extremely low installation cost + Energy free + maintenance free 24/7.
High flow water even during black out.
Well, it is an excellent option for those who have high water pressure.

I live in JB and water pressure is very good thus far.
Where do you live? It is quite rare to see the water pressure dropped after neighbor moved in.

There are always pros and cons.
It is just another option.

Hi guys,

Am thinking of getting Grundfos pump for my new house too. Seems that the CH2-50PC has been replaced with newer model CM3-5PC. Just wondering, normally where do people put the pump...on the roof? That means have to spend $$$ to build a shelter specially for the pump? Any other places to put the pump? Also, do we need to redirect the pipes for kitchen so that water will come from the pump as well? Coz if not mistaken, originally the water for kitchen is direct from pipe and not from tangki...

Zheilwane, can please pm me best price for the CM3-5PC pump? Thanks!

Unfortunately, i cant quote prices online. However we are having MERDEKA SALES and today is the last day. We are open from 9am - 6pm.

Here is our location
https://maps.google.com.my/maps?q=3.211378,...&num=1&t=m&z=19

Why go PERFECT LIVING? Drop by my showroom and if u are not impressed with our price and service, you can go to perfect living on SUNDAY. Moreover, whatz the rush? Homedec is coming soon as well. There are many exhibitions every year but our SALES is only first time in this year.

Usually on the roof, water have to tap from water tank. Can't pull from direct. Is illegal.

Hmm, nvm it's ok, understood that you're protecting your business...just in case i'm a spy for your competitors huh Thought of getting the price through pm (like what i saw here: http://forum.lowyat.net/topic/1636923/all) coz i'll then have a rough idea how much it will cost instead of driving all the way to your shop.

Thanks for the info, weikee.

thanks all the reply

will 0.5HP of water pump sufficient for the DS terrace house with 4 bathrooms and without garden? It pumps from 1500L water tank.

the pump is located where ? the water tank located where ?

the pump and tank will be located at backyard.

actually it is not really accurate to look at HP. For grundfos, CM3-5, Cm3-5, CM 5-3 and etc most of them are 0.5kw = close to 0.7hp. However, the performance and price of each model are different.

SO why they have the same HP yet performance is different? Reason, they are using the same MOTOR but number and size of impellers are different.

on ground floor ? better check the pump to see the specification on the pumping height...

water is damn heavy to pump up... if double story...

its easier to pump down due to gravity.. and harder to pump up


http://www.rpc.com.au/pdf/Grundfos_CM_DataSheet.pdf

specification for the cm pumps, look at the curve graphs to get the best height/flowrate for your usage...


This post has been edited by JinXXX: Sep 22 2012, 10:45 AM

Don't go against gravity.got to pay more for that. Pump need to work hated.

Bought the Grundfos pump from zheilwane during Merdeka Sales, really good price.
Installed and test paip leakage today, so far so good...
The pressure is pretty high and is really good for the rain shower setup (bought from zheilwane also) ....
Thank you zheilwane and family who served me well while I shopping at his shop....
Thumb up for u....

thumb up to zheilwane...even though I never met him and even go to his shop, I would pretty much confident!! because of his knowledge sharing as well, I have decided to go for grunfos!!

anyway, i'm using grunfos pump as well...240 if I not mistaken..not really remember the code..anyway, yes it will somehow increase your electricity but you will be more than happier to take bath, wash and anything related to the water...

for electricity, make sure you built up some power switch so that you can turn it off when no one is in the house.. =)

would like to ask that, will 1hp of water pump consume a significant electricity as it operates 24hours (of cause it on/off only when there is a usage) and has a same horsepower as air-conditional too.

Hi guys,

Need opinion for this water pump brand call "Tsunami"

Price quoted RM 750 for 0.5 hp with 2years warranty.

Please give some comment as planning to get one for my new house.

Thanks

Hi, may I know how to test for piping leakage after install the water pump?

From my experience,if you are planning to install autopump,you just need to make sure your pump is not running when you have close all the pipe that using water from tank after installation.if the pump still running,then there is a leakage.. =)

This post has been edited by chole17: Sep 23 2012, 06:57 PM

Yes. the plumber will fix the water pump and leave it for few days to test the leakage.
If the water pump is switch on during no usage of water means got pipe leak.
Furthermore, they will run the water pump with one water tap on and check whether the pressure will cause the leak or not.
The different between pump and without pump is big.... the worry is the old pipe can't stand for the pressure....

Added on September 23, 2012, 11:07 pmMost of my contractors recommend Grundfos...
There are alot of water pump in the market. Although grundfos is expensive compare to others, but this is the problem less compare to others.
Can u imaging the hassle you need to go through when u having the water pump problem?
So, pay slightly more for the reliable product....

This post has been edited by winlose2582: Sep 23 2012, 11:07 PM

Anyone here using Tsunami? Pls comment....

Thanks for the tips. I neec to check the pump that I installed is Auto pump or not. I think should be la. How to check wether my pump running or not? Need to climb to the water tank to check it out?

off power to pump.. see the flow/pressure

on back power to pump.. see the flow/pressure

Hi,

I just install a Grundfos CM3-5PC and the water pressure is very strong, I have 4 bathroom. My wife is complaining that the pressure is too strong.

Now I may have a problem as I have Water Heater tank installed for every bathroom, the Groundfos is install to supply pressure to all including all the water heater tank. So now even the hot water comes shooting out. Just imagine if I turn the Shower Mixer lever all the way to the left only hot water comes shooting out. I could be cook now I am looking for Shower mixer that can limit the flow of hot water like limiting the lever from turning all the way to the left. Any suggestion ?

jackdon

Pressure reducing valve might be a solution.

The mixer can adjust the water pressure la.

Hai WeiKee,

I have a single lever shower mixer wall mounted type. Pulling the level up will turn on the water flow. Middle position I believe will be 50% hot 50% cold but if I mistakenly turn all the way to the left 100% hot water will come out. I want a mixer that can limit the max amount of hot water to comes out because right now both the hot and cold water have the same pressure.

Any model that can regulate or limit the amount of hot water out.

jackdon.

Got model and picture? I use so many shower mixer in many hotel, cheap, average, and expensive all can adjust. You can try pull the level to 50% up

adjust the pressure switch, set it to lower cut oof presure @ 30psi


install a pump to increasre pressure then install a PRV to reduce pressure doesn't sound logic lar...

good mixer yes, can lift the level 50% to limit flow. but for those chap ayam, lift 50% / 70 % /100% no different one

Sound like buying a fast car and put a speed controller because throttle cannot be control.

hahaha.. lucky i didnt get grundfos.. like i mentioned in some of posts in waterpump/grundfos thread...

its OVERKILLLLLLLL

suddenly regret getting such a powerful pump

Hi Weikee,

Yes I know we can regulate how hot and cold we want by just adjusting the lever up and down left and right. But what I want to to LIMIT in case of we sometime forget or the wife or friend or kids turn the lever all the way to the left and 100% hot water shoots out.

The model I install now is Rubine RT-SP022CR Bath Shower Mixer and I actually wrote to rubine.com.my customer services. And their reply is that they do not bring in model that can regulate limit the amount of hot water. There are model that are thermostatic and would works if both side has the same pressure and would be able to regulate the amount of hot water mix. And I also google and found that there are Mixer that can adjust the max angle the level can turn to the left to prevent 100% hot water.

Added on September 28, 2012, 10:30 pmFYI it is not an overkill on the cold water side, we need that kind of pressure for the volume of water to a big RAIN SHOWER... and I can tell you suddenly my shower can be really refreshing . My problem is that the hot water also same pressure and volume and accident is just a turn of the level to the left. A pressure reducing valve on the hot water side would be my last solution.

jackdon

Erm, usually people will just lift the lever up 50% then adjust the preferred temperature, rarely will turn full to hot den lift up the lever. Kids nowadays are very smart, can play Ipad i guess if u teach them once, they will rmb. If you are using a storage tank, i guess there is a button to reduce the max temperature.

Grundfos pump is powerful, if you are those who wants to get rain shower and have strong water pressure like hotels then GRUNDFOS is the choice. There are some customers who told me, just shower 5 min only, no need so good one, then get an instant heater with built in pump.

This post has been edited by zheilwane: Sep 28 2012, 11:25 PM

You need to have same pressure if not you have problem adjusting the mixing. What happen if in a cold day, your mixing maybe is 6:4, and you limit the water pressure to only 5, you will only get 5:5 and maybe is not hot enough? I know we seldom use until 50% mixing of hot water in our weather, but is just a scenario. Assume if really cold morning after a long rain (day and night).

Just need to change the habit. Is not easy to find that type of mixer, I know what you referring, this type of mixer have a fail safe switch to prevent you to turn max to hot water. You need to press the small button to move max. But I find it useless. My 4 years old daughter already know how to adjust the water temperature she need. I think we adult can do better.

Do you know which Grunfos pump suitable for landed house? My house have 3 toilet.

You can check with the seller few standard type good for terrace house. And some come with pressured air reservoir and need recharged.

you may go for Grundfos CM34PC. The pump seller proposed this model to me as well.

May i know how much you brought?

Go Hardware Builder or JF Home to check the price. If you stay near PJ, Subang or Kelana JF-Home is easier and open on Sunday. Kepong area H/W Builder will be your best location.

Sometime CT-Hardware also have good promotion price for Grundfos, check it out.

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..

CMH series horizontal multistage stainless steel centrifugal pump is segmental multistage stainless steel pump.

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.


Crow

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.

Crow

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

This post has been edited by crow190569: Mar 7 2014, 11:02 AM

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

Thanks for the info.

I'm looking for water booster pump, and realized seller recommended 2 brands: Grundfos (cm5-4pm1) and Tsunami (CMH4-4k).
Which better brand in terms of maintenance, lifespan and performance.

my plumber is charging me rm550 for installation only including washing tangki.
price reasonable?

hi..so have you diecided on the pump?

i am also torn between these two. price diff around RM 400

then what brand u recommend?

This one suitable for you

sexpensive bro.. my house has only 2 toilets. wasser brand good? cheap only rm400

Grunfos got so many model to choice n which shall be the best choice ?

I'm looking for water pump to supply 2 bathroom Apartment. Any recommendation?

At most, onky two bathroom will be used at the same time, so i wonder what power and hp i should be looking for? The washing machine and kitchen are all using direct water, not from tank.
