    • Description

    For a standard 100L water geyser in South Africa, the non-return valve (NRV) is typically a 15mm brass spring-loaded non-return valve (rather than a 100mm industrial or drainage pipe valve).

    Key Installation Notes

    • Check the Flow Direction: Look for the stamped arrow on the valve body; it must point toward the geyser inlet so water can flow into the tank but cannot push back into the municipal mains.

    • Pressure & Safety Combo: A 100L geyser setup normally pairs the 15mm non-return valve with a pressure control valve (e.g., 400 kPa or 600 kPa) and vacuum breakers depending on your local installation layout.
