Hi water pump experts,

I owned a 2 storey house with 3 bathroom. I would like to ask a few question:

1. My house water pressure right now seems to be ok from the direct water to the kitchen sink, washing machine and also to fill up the tank at rooftop slab for now. The neighborhood only have half resident for now, and maybe by next year every resident will start living in the area, will it effect the water pressure to my house?

2. Both of my second floor bathroom have a very low water pressure, so everytime I need to take a shower I need to run downstairs for shower. A plumber recommend me to setup a waterpump at the rooftop near to the tank so that it can give more pressure to the water for my upstairs bathroom. After Ive done the power point for the rooftop suddenly he changed his mind and said that it is dangerous if I put a waterpump at the rooftop slab (it may flooded the area if the waterpump is broken) and hard to maintain. So Im kind of puzzled and trying to research if it is true that waterpump should not be at the rooftop or not because if its true then Ive wasted money from his previous recommendation. So It will be very much helpful if you guys can share your experience with me.

3. Other plumber suggest to bypassing direct water to the tank and used direct water all over the house and use only one waterpump at the car porch area which I cannot imagine on how the system works. Is it better this way? or I just put a waterpump at the rooftop is enough?

4. Was about to buy a hitachi water pump until I stumble into this forum, don't know about this brand but I wonder what is the best pump to cover a two storey house with 3 bathroom. Thank you in advance

Thank you for the info. Didn't know that its illegal to pump directly from main meter. A few neighbors here already use water pump from their meter so just I`m curious.


Thank you for your recommendation. Is teral a good brand as grundfos? I tried to buy once item that would last very long type of guy. Is that teral ab25x254tpc enough to support all 3 bathroom at the same time? My house tend to get many visitors from my spouses, they like the free room while on vacation. As for grundfos which model should I go for? I live in Perlis, hard to find good plumber here. Do you anyone that can setup the water pump here? Thank you again for you help

Do you mind to share the picture of installation if you have? Can it be installed bare on the roof?

I just got back from the store that sell grundfos here and he said that I should put it in a cover. If I buy grundfos does it include the cover altogether or I need to buy them separately? If separately where I can get one?

The Scala 2 is out of stock, which one has similar performance that has the capability to supply 3 bathroom from the rooftop? Thank you
