I live in a landed double storey terrace house (~10 yr old house) in Shah Alam/Klang area, moved in not too long ago and first time home-owner. Very noob.

Let me split this question to 2 parts.

Part 1 - Water Pump:

I find that the water pressure in my house (most importantly outside garden area water outlet, kitchen sinks, toilet bidet, shower) is quite low. Even some contractors who come to my house and fix some things told me this, and apparently nothing much I can do except install water pump.

So, my question what kind of water pump do I need? Do I need to install 1 outside my house? Do I also need to install 1 inside my house since there is a water tank? (I think there is, because when there are water cuts, I can still get water in my toilets even though kitchen no more water).

How are they powered, do I need to do wiring and install new switches somewhere?

Also, any recommendations for water pump? I've been suggested Tsunami before, but never really looked deeper than that (because I don't know what I need).

1 recent problem I've been having also is that stray cats have been coming and leaving their poop at my house. My outdoor hose water pressure is low, so cleaning this is a hassle.

Part 2 - Water Filter:
I plan to install water filter to clean whole house water, because I have eczema (which only started a few months after I moved in this house) and I suspect maybe its because the shower water is unfiltered. I was looking at Nesh, and they recommend for me to install the water pump first before filter.

Any recommendations on water filters? I don't really want to spend a bomb (Nesh is between 2k-3k roughly). They told me filter replacement 5-7 years with proper maintenance, which is between 700-1k. I also browse here and saw some people combo their filters with the cheap 10" PP filter because it apparently helps the filter last longer?

Hope sifus here can give good advice!

I see.. Can any handyman/plumber do water tank cleaning? Or need to find those who can do it specifically? I assume they would also be able to advise if the pipes can withstand water pump pressure?

Also, I'm currently using the Joven shower/water heater, and it does come with built in pump. But still the pressure is quite sad one.

Sorry just to make sure I understand, means got 2 water pumps? 1 from main supply to tank, and 1 from tank to the whole house? Or did you mean only 1 water pump, from the tank to the whole house?

If its the second one, does that mean that only the areas that gets water from the tank benefits? So for example my outdoor hose still low pressure?

(1) Not entirely sure. There was 1 day where I noticed that my water pressure was lower than usual, but when I asked my neighbor, they said theirs is fine.

(2) Yes definitely seen this brought up in other threads as well. Plan to get a plumber to check to make sure.

Thanks for the responses @stormer.lyn, @ongss.

So basically what I'm getting is:
1. I can't install an outdoor water pump, as Air Selangor does not allow this.
2. I can install a water pump from the water tank - but if I understand correctly, this will basically only affect my bathrooms, since I think my outdoor hose and kitchen water comes from the main supply.
- Unless I do what @ongss did, and route all my water to the water tank first, then distribute to the house.
- Based on @stormer.lyn's info, water from main supply is "technically" potable while water from tank is not, as not guaranteed to be bacteria free.

Out of curiousity, what is the cost to do something like this? And also wondering why do you need 2 big tanks, and where did you put them? On the roof?
