Upgrading Your Pressure Tank: When & How to Do It (Singapore Guide)

A pressure tank is designed to last years, but like any part of your water system, it eventually wears out. If your tank is old, leaking, or causing your pump to work harder than it should, it may be time for an upgrade.

Here’s how to know when it’s time to replace your pressure tank, what to look for in a new one, and how to plan a smooth upgrade.

Signs It’s Time to Upgrade

The tank is more than 10 years old
You hear the pump cycling every few seconds
Water pressure is inconsistent or too low
There are visible rust spots or water leaks near the fittings
The bladder or diaphragm fails frequently, requiring repeated air refills

If you’re seeing these symptoms, upgrading to a modern tank can save money in the long run.

Benefits of Upgrading Your Tank

Better water pressure: Newer tanks maintain consistent pressure more efficiently
Longer pump life: Reduced pump cycling prevents premature motor burnout
Lower maintenance: Composite and stainless steel tanks resist rust and last longer
Energy savings: Properly sized tanks reduce electricity use by minimizing pump starts

Choosing the Right Tank for Your Property

Tank Size: Select a size based on household water usage, number of occupants, and peak demand times
Material: Choose between steel (budget), composite (balanced), or stainless steel (premium)
Location: Make sure the tank fits the available space and complies with condo/HDB rules

Installation Considerations in Singapore

PUB Compliance: Ensure the tank and pump system meet local water safety standards
Pipe Size Matching: Your installer should match the tank’s inlet/outlet size to your existing plumbing
Pressure Switch Calibration: After installation, the cut-in and cut-out pressures must be set correctly for your new tank

The cost depends on tank size and material:

Steel Tank: ~$350–$500 including basic installation
Composite Tank: ~$500–$700 including installation

These prices can vary based on complexity, additional fittings, and pump adjustments.
