Hi, I'm planning to install stainless steel water tank and water pump booster at home. its a single story bungalow unit (just average), 3 bathroom, wet kitchen and dry kitchen. only 3 people staying at a time and once in 2,3months will have occasion with high consumption of water. the water pressure now are definitely slow especially for the shower. that is why we planning to get water pump and water tank.

my question is, for this kind of household, how many liter of tank is required to cover our water consumption? 1000liter? 1250liter? or more? i already survey for few brand like Kingkong and deluxe. and for water pump i'm considering Grundfos Gemini EP240PC.

NEED URGENT HELP FROM YOU LOVELY GUYS
