Hello guys, have anyone here installed the water pump outdoor and made a cover for it to protect it. Looking for any cheap solution of those....

I am thinking the same too. But i think most likely i will go for grundfos scala2 which is built for outdoor usage. Which means you don’t need extra cover.

I am also looking for a cover to protect my water pump. Got quoted RM280 for one which I think is a bit high considering it’s just a plastic

Can anyone recommend a reliable water pump and installer for a 2 storey house with 3 bathrooms? House in puncak alam. installed water heater with pump but pressure not strong. Thanks

as per tagged message, 3 bathrooms can use teral AB25x254tpc. However, installer only available in feb a now all on holiday d

Hello,
Need your advise.
Should i install water pump for single storey landed house. 2 bathrooms only. Want to install rain shower. Please advise. If yes, how many hp and what brand.

Thanks.

if u wan strong pressure, definitely need a water pump

2 bathrooms, grundfos cm3-4pm1 is sufficient but if u like strong pressure cm3-5pm1 has better power

another alternative would be teral ab25x254tpc and ab25x255tpc equivalent to grundfos above

Thanks. Seems Teral is more affordable.

Can follow this thread. Grundfos is good, make sure you get full metal version. You will have to relood into the water piping because your old pipe may leak if water pressure are too high.

0.5hp ok ar for older house ?

hp won't tell much, you need to read the flow rate and PSI of the pump in the spec.

Old house have the risk of piping unable support the high pressure due to pump.

Hi everyone.

Would like to ask some questions about installing a water pump for my house. It is located in Putrajaya, with 4 bathrooms, and the house is around 20 years old. Questions are as below:

1. Would a plumber/installer be able to come to my house and examine my house piping to see if it is suitable to install water pump before we make any decisions? We do not mind paying if we can confirm the state of our piping.

2. All bathrooms currently use water heater with dc pump. Do we need to replace/get rid of them if we install water pump or can we continue to use them?

3. Do we need a pump that is powerful enough for all 4 bathrooms? The 4th bathroom is only used when there are guests, which is rarely used nowadays. Can we get a pump that is good enough for 3 bathrooms?



Any contacts or recommendations for shops that cover Putrajaya area would also be appreciated. We could also use contacts for electricians as we need someone to install wiring if we decide to install a water pump.

    if you can check those pvc pipe rating if class 0 means lowest rating i wont even try installing a pump.
  Class  B PN6 = 6 bar max
  Class  C PN9 = 9 bar max which already exceed most household pump rating.
  Class D PN12 = 12 bar max

As for personal practice, i will suggest using min Class C or  D  even highest class 7 if you can afford for peace of mind to compensate for all the errors which the normal contractors might do.

Branded(example: binaplastic or rasintech) / higher rating pipe will have fewer chances of having voids or thin walls inside the pipes.

Normally are the joints that have problems. those who lack of experience handling pvc pipe tend to use cheap glue/ didn't apply glue properly and dont allow it to cure long enough before testing the system.

2. All bathrooms currently use water heater with dc pump. Do we need to replace/get rid of them if we install water pump or can we continue to use them?

depends on the pump you coose and the max allowable pressure for those heaters, higher pressure will normally break the seal of the pumps which will cause it to leak.

my rule of tumb for normal household usage is around 3-3.5 bar of water unless certain accessories required higher pressure rating, for example, some shower head. you can choose a 3bar pump at higher flowrate.

you can use this guideline for flowrate required for pump selection:

Water taps 0.2~0.3m3/hr
Showerhead 0.3~0.5m3/hr
water spray 0.5m3/hr

you should ask yourself how many people will occupy the toilets at 1 time which will cause drop in water pressure when it dont have enough flow.

Hi, i also encounter this pump.
it's selling rm1399 with installation and a free high pressure cleaner.
had you find out any information about this pump?

I was thinking to put the water tank from roof to the ground(open area). What is your recommendation?

Please advise. Thanks.

Got your answer from other thread. Thanks.

Not much information/review about this pump so i also don't dare to take the risk for install it.

eventually which pump you install? Scala 2?

Dear All i would like to ask that water pump have buffer tank. The water pump i purchase is normal without a small water buffer tank attach on top of it. My supplier advice me to add another RM150 to attach a small 8 Liter small water buffer tank to attach on it. He claim that this can reduce the pump working frequency (example open water tap wash hand pump won't run) hence less maintenance and longer life span.

May i know what he say it is true? It really a lot benefit to add the water buffer tank and RM150 is fair price for the tank? Thank you
