I think I saw you recommending cm3-4pm1 on an earlier posting. What are the key differences? . Can you also please pm me the price of both these models and let me know you take credit cards or not. Thanks.

CM3-4PM1 is slightly weaker. If u r happy with CH2-50PC then get back CM3-5PM1, if u wan something a little weaker than CM3-4PM1, price difference RM 50 only, hence most customers get 3-5

I bought a CM3-5PM1 yesterday from zheilwane (Builders Hardware Enterprise).

Excellent seller in terms of responsiveness, explanation, price and after-sales (convenient delivery & info on warranty registration).

He spent time to give me good info on pros/cons of different models, on what to consider when buying. Dude knows his stuff. You can seriously ask all the questions you want on the product/installation and he will either have the answer or help you find the answer. Made my decision process much faster.

I needed it quite quickly so he delivered much earlier than I requested as well

Thanks man, will definitely consider buying from you again if I need more bathroom/kitchen equipment!

Bought Scala2 few weeks ago, am really satisfied with it. Staying in a 2.5 storey house, 4 bathroom and 1 water storage tank.

Scala2 adjusts the water pressure smartly and I might say perfectly. It starts pumping once it detects tap is running and stops if there is none.

One of our pipe is leaking underground (we can hear the water gush when using our previous pump). Scala2 detects the leakage with an error indicator and doesn't pump water if there's no usage of water thus doesn't make the leakage worse.

Mind to know where do you get your new scala2 and also the price? I planning to put a water booster to my new double storey house with 3 bathrooms. Grundfos is a leading brand with reliable quality as review from online through it seems not cheap.

Bro, I'm from Kota Kinabalu. So, I did a bit research online and found that they have a dealer here.

The price including installation is around RM2,300.00.

The CS told me that this model has been tested in the California or Texas desert or something for 3 years... so, it is compatible with Malaysia's climate. Furthermore, there's no need to turn off the pump.

Thank you Zheilwane's explanation here, which triggered me to drove all the way from Cheras to Kepong (Builders Hardware Enterprise) for almost every thing I need for my new house.

His dad assisted me, good advices and reasonable price.

Grundfos CM3-5PM1 vs scala2, which one best in term of reliability? thanks

Thanks

i vote CM3-5PM1, this has been used in Malaysia for many years while scala2 is new. So, all customers reviews that grundfos is GOOD is actually referring to CH-PC model which is then upgraded to CM-PM (current model which is quite similar) but Scala2 is a totally new design

COmpared both, noise level wise CM3-5PM1 is lower compared to Scala2 but if u r staying in and old house and worry pressure too strong then get scala2 with variable speed and adjustable pressure

Thanks for your great explanation! Have a good day!

Hi guys,

Need advice here.

My 3 years old CM3 has given me problem lately. When the tap is open, sometimes it takes about 1 minute or longer for the pump to kicks in. From the pump indicator, it seems the Power and On indicator are lit, and Faulty not lit. You can hear the pump sound (i assume that's it's running).

Anyone experiencing this before? Care to share?

Many thanks!

hi guys,

any recommend pump for low water pressure for terraced house?
I think the water pipe aged 30+ years, would change to new pipe can help to resolve the issue?

Thanks

It is regarding CM3-5PM1,

I am staying in Condominium and the water pressure is just normal volume, i like to bath with more heavy water pressure.

can i install CM3-5PM1 after my in house water meter? will it cause leakage and burst toward new PVC piping in the unit?

is this pump having water pressure control? appreciate for the answer . thanks.

Get grundfos Scala 2 better for your case.

Regarding pipe burst, many forumers asked this question as well. Pipe burst has nothing to do with the pump but is due to the poor installation of the pipes. Why other houses or condo install CM3-5PM1 did not burst or leak while some YES. reason is the pipe not the pump. If old house and you have no confident with the pipe, scala 2 with variable speed is a better option.

too bad i had already purchase CM3-5PM1. shouldnt be a problem to install right？my water pipe is newly laid and install.

I am comparing Tsunami, Gemini and Grundfos now.

Anyone using Tsunami pump here?

My family experience with Grundfos pump at home:

I moved into a 3 storey house near 10 years ago, installed a Grundfos CH2-50 from my water tank outlet during renovation and been using it ever since. The water tank area and all the outlet pipes are in open air subject to sun and rain in my roof area, so the pipes all suffer some form of sun and rain. As the years go by, my dad and I have to cut and repair cracked pipes due to the high pressure and exposed pipes. We have so many rejoints now that we just replaced a full set of all the piping once early this year. Just to be clear, all our pipes are rated class 7.

Not to scare anyone away from using Grundfos pumps, but they are a powerful and highly durable workhorse. Just make sure you know where all your pipes run, cuz as your pipes age it may crack and some joints may also come loose due to vibration. Always pay attention to your pump making noise, if it makes noise too frequently even when no one has been using any water for some time, then u potentially have a pipe leak somewhere.

your previous pipe also class 7? or just changed to class 7? PVC class 7 is very good

my in law house using PVC class 6, while my house is ABS, so far no issue

However, both also under the roof, not exposed to sun.
