Introduction
RO systems are a game-changer for clean water at home or in commercial spaces. But for your system to work effectively, you need a reliable RO pressure tank. In Kenya, these tanks are becoming increasingly popular due to rising demand for clean, safe water.
What is an RO Pressure Tank?
An RO pressure tank is a storage unit that holds purified water from your reverse osmosis system. It ensures you always have ready-to-use clean water without waiting for the slow filtration process.
Why You Need an RO Pressure Tank
Ever turned on your RO faucet and waited forever for water to flow? That’s where the pressure tank comes in. It stores filtered water and uses pressure to deliver it instantly. No tank = long waits.
How RO Pressure Tanks Work
Inside the tank is a bladder or diaphragm that separates water from air. As the RO system fills the tank, pressure builds up. When you open the tap, the compressed air pushes the water out quickly.
Components of an RO Pressure Tank
Steel/plastic outer shell
Internal bladder (rubber)
Air valve (like a bicycle tire)
Water inlet/outlet valve
These parts work in sync to make sure your water flows fast and clean.
Types of RO Pressure Tanks
Standard Metal Tanks
These are the most common types, usually coated with food-grade epoxy inside.
Plastic Pressure Tanks
Made from high-grade polymers, lighter, and resistant to corrosion.

RO Pressure Tank Installation Tips
Ensure the tank is placed on a flat surface.

How to Maintain Your RO Tank
Check air pressure every 6 months.
Sanitize the tank once a year.
Replace bladder if you experience low pressure even when the tank is full.
