How to Choose the Right Pressure Tank Size for Your Singapore Home
Introduction
In Singapore, water pressure is one of the most common household frustrations — weak showers, pumps constantly cycling, and higher utility bills are all signs of an undersized or poorly selected pressure tank. Choosing the right size tank is not just about convenience; it’s about long-term efficiency, pump protection, and cost savings.
This guide will walk you through everything you need to know about sizing a pressure tank correctly for HDB flats, condos, and landed homes.
Why Tank Size Matters
Too Small = Constant Cycling
When a tank is too small, your pump turns on and off too frequently. This burns electricity and drastically reduces pump life.Too Large = Wasted Cost and Space
Oversized tanks cost more, take up space, and don’t add extra performance beyond what your system needs.The Right Size = Perfect Balance
The goal is stable water pressure, reduced cycling, and efficient pump use.
Key Factors in Sizing
Household Size (People)
2–3 occupants = smaller tank (20–30L)
4–6 occupants = medium tank (50–80L)
6+ occupants or landed homes = large tanks (100L+)
Pump Flow Rate (L/min)
Your tank should be able to hold at least 1/3 of your pump’s flow rate.
Appliance Demand
Homes with multiple showers, washing machines, or irrigation systems need bigger tanks.
Tank Sizing Example (Singapore Context)
3-Room HDB Flat (2–3 occupants): 20–30L tank sufficient.
5-Room HDB Flat (4–5 occupants): 50L+ tank recommended.
Landed House with Garden: 100–200L for irrigation and multiple bathrooms.

FAQs
Q: Can I upgrade my tank later?
Yes, but installation is more costly. It’s smarter to size correctly from the start.
Q: Will a bigger tank save more energy?
Not always. It must match your pump flow. Oversizing doesn’t equal savings.
