A flush valve helps periodically clear accumulated salts and particles from the surface of your RO membrane by allowing a burst of water to flow through and wash them away, which helps extend membrane life and maintain consistent purification performance. Whether your system uses a manual flush valve you operate periodically or an automatic flush mechanism triggered by a timer or the system's electronics, a malfunctioning flush valve can lead to faster membrane fouling and reduced water output over time. Our technicians inspect the flush valve mechanism, checking for stuck components, worn seals, or electrical faults in automatic flush systems, and repair or replace the valve as needed. For manual flush systems, we'll also walk you through the correct flushing frequency and technique so you can maintain this simple but valuable habit yourself between service visits. Keeping your flush valve in good working order is a small maintenance detail that pays off significantly in extended membrane life and more consistent long-term purification performance.
