The water in my area right now is kind of bad due to high demand, low output and drought. I was thinking of putting this to filter the outside water. Already have a Coway for drinking but for other stuff the water quite karat. Is this Coway Bamboo good? Or should I go with something else? Can recommend?

RM5k? RM10k? I am a total noob in this. I don't know what is the market value for this thing. Something that last and easy to maintain I guess. What are my options?

The water from the main pipe is low pressure-so there is a tank that collects water from there. Then a pump pumps it to the tank at the second floor. I am not sure if placing the pump at the main pump can be done due to the pressure.
