The storage tank in your RO system holds purified water under pressure so it's ready to dispense the moment you turn on the tap, without needing the pump to run every time. Over years of use, tanks can develop internal rust in metal-bodied units, cracks or leaks in plastic tanks, or a failing internal bladder that reduces effective storage capacity and water pressure at the outlet. Signs you may need a tank replacement include visibly reduced water pressure even after filter and membrane checks come back fine, water that tastes metallic or stale from an aging tank interior, or visible leaks around the tank body itself. Our technicians assess whether the issue is genuinely the tank or a related component like the solenoid valve or outlet fitting, then fit a properly sized replacement tank matched to your household's typical water usage. We also sanitize the new tank connection points during installation to ensure the freshest possible start for your purified water storage.
