question for Zheilwane.

the pump that your proposed ch2-50pc. is it running all the time even we are not using it.

or it will turn on when it detect water flow through it.

tq.

Can Grundfos Water Pump place out of roofing area, where direct under sun or rain?

CH2-50PC has been discontinued and now replaced with CM3-5PM. U can leave it on 24hours and it only operates when there is water movement (pressure drop).

Nope, you will need to get something to cover it

am looking for grundfos pump too to solve my water problems too.
its a 2 storey and a half what should i get?

usually we spec base on number of bathrooms and type of shower (rain shower 8,10 or 12? / Hand shower)
Usually Grundfos CM3-5PM is good enough

rain shower 8,10 or 12? is it the diameter of the shower head? and my house got 5 bathrooms all 5 of it have shower

yup diameter. Then i would recommend u to get CM5-4 or CM 5-5

My house is 3 storey with flat roof on 4th level. Existing water pump is on level 4 but it is faulty. I hav 4 bathrooms with 4 showers, 4 bidets, 7 sink taps n 2 outdoor taps. Any recommended brands n models? Urgently needed. Thanks

You can get Grundfos CM 5-4PM. I m using this model for my 3 storey house also, with 10" rain shower heads in all bathroom. If u wan something with consistent water pressure and something not too strong, u might wan to consider to get a higher model which is Grundfos UNI E CM 5-4

zheilwane,

If only for one bathroom with rain shower.
Any recommended brands n models?

Zheilwane,

I plan to install a pump for 3 toilets (all located at 1st floor of my double storey house). All toilets will have medium sized rain shower head each, and only 1 toilet with long bath. Which pump model do u recommend?.... All water points at ground floor not connected to the pump system. Tq

Why not try Clazzen water Pump ?. I have been using it for several months and it is reliable pump and silent too. I get this from my vendor Chris 017-3976081

Dear all,

I couldn't find the model at the Grundfos website.
I only found CM series models. I am very confuse because Grundfos has many types of pumps.
How about Hitachi brand?

U can get Grundfos CM3-4PM

Grundfos CM3-5PM would b sufficient

Grundfos main pump for household is CM pump. What model u r looking for? I notice other shops are confusing customers by giving gemini or advertising grundfos logo but model given is another brand (misleading customer)

Hi zheilwane,

I don't know. I went to a 2 hardware shop selling Grundfos water pump. Both of them seems like don't know what they are selling.
I ask which one suitable for 3 bathrooms double storey terrace house? all can use. idiot answer.
Like that I also can answer lar. tell me the differences.
My house is new but the water pressure is extremely slow. No water in some tap if open concurrently.
I complaint but the developer said is due to air inside the pipe.
Will get better after usage. Is it true?

all landed properties have weak water pressure, thatz y ppl install water pumps. If u need more info why not drop by our showroom

The contractor said if I install water pump. I need to install also the water tank.
If not, my neighbour will suffer water pressure loss when my pump is on.
Is it true?
