Q1: Our apartment building is 5 storeys tall and I live on the 4th floor. Do I need a booster pump?
A1: Highly recommended! Residents on the 3rd floor and above are all advised to install one.
Because the 3rd and 4th floors are too close vertically to the rooftop water tank, the water pressure is insufficient, which easily leads to:
Low water flow from taps and shower heads, making showers unpleasant...
