FAQ
1. What is the typical service life of a reverse osmosis pump?
The service life of a reverse osmosis pump depends on the operating environment, water quality conditions, and routine maintenance practices. With proper maintenance and reasonable usage, its lifespan typically ranges from 5 to 10 years, with some high-quality products lasting even longer.
2. How can I determine if a reverse osmosis pump needs replacement or repair?
Signs such as significantly reduced pressure output, diminished water flow, abnormal operational noise, or water leakage may indicate pump malfunction or wear. Prompt inspection and subsequent repair or replacement are necessary.
3. Can reverse osmosis pumps handle high-hardness water?
Yes. High-quality reverse osmosis pumps are typically designed with corrosion resistance and anti-scaling features, enabling them to handle high-hardness water. However, regular cleaning of the pump and system is recommended to prevent scale buildup that could impair performance.
4. What precautions should be taken during reverse osmosis pump installation?
Ensure the pump is installed horizontally to prevent vibration and loosening. Verify that all pipe connections are properly sealed and confirm the power supply voltage matches the equipment requirements to guarantee safe and stable operation.
