Top 5 Reasons for Abnormal sounds or Vibrations from your RO System

Updated: May 6

A Reverse Osmosis (RO) system is an indispensable tool for clean and safe drinking water, especially in the Middle East. If you use a commercial RO plant, an abnormal sound from your RO plant or RO system vibrating noise can cause concern.

Understanding the reasons behind these unsettling sounds and vibrations is crucial for the longevity and efficiency of your system. This article explores the top five reasons you might encounter these issues, accompanied by some frequently asked questions for additional clarity.

Abnormal sounds or Vibrations from your RO System

Reasons for Abnormal sounds in an RO System

1. Improper Base Placement

When positioned on an uneven or unstable surface, the system can generate abnormal noise from your RO system. Such imbalances can negatively impact the RO system's long-term performance. A simple realignment on a level surface can often alleviate these issues, restoring the RO plant to a quiet and efficient one.

2. Inadequate Vibration Pads

If you notice your RO System vibrating excessively, the culprit might be inadequate or worn-out vibration pads. Designed to absorb and minimize vibrations, these pads reduce RO system vibrating noise when functioning correctly. When worn or dislodged, their efficiency drops, increasing periodic noise and vibrations. Periodic replacement or adjustment can resolve this issue.

3. Loose Fasteners or Nut Bolts

Loose components can be a common reason for RO system drain noise or an RO filter making a buzzing noise. The nuts or bolts securing your system can loosen over time, rattling and causing disruptive noises. A routine checkup and tightening of these elements can nip this problem in the bud, ensuring quieter operation. These are the red flags that call for maintenance of your RO system.

4. Pressure Variation

Pressure irregularities can lead to a humming noise from your RO system. Sudden or frequent variations in pressure can disrupt the water flow rate, triggering abnormal sounds from the RO system. Proper Reverse Osmosis System troubleshooting can diagnose this issue and provide a targeted solution to ensure consistent pressure levels and, by extension, quiet operation

5. Lack of Preventive Maintenance

Preventive RO system maintenance is your best defense against many issues that can cause abnormal sounds or vibrations in your system. Regular check-ups and maintenance routines can preemptively identify and resolve potential problems before they worsen.


Understanding the reasons for abnormal sounds in an RO System and performing a troubleshoot are crucial to ensuring your unit's long, efficient operational life. Whether the issue stems from improper base placement, worn-out vibration pads, loose fasteners, pressure variations, or inadequate maintenance, it's essential not to ignore these warning signs.

By regularly scheduling RO system maintenance, you can preemptively address these issues, ensuring that your system continues providing clean and safe drinking water for many years.

How do you remove air from the RO system?

Air trapped in the system can produce abnormal noises. The best way to remove it is by running a full tank of water through the system and letting it refill, thus alleviating potential abnormal sounds from your RO system.

Is It Normal to Have Abnormal Sound in RO System?

No, experiencing abnormal sounds from your RO system is generally not expected. A well-designed system should operate with minimal noise, ensuring peace of mind.

How do I stop my reverse osmosis system from gurgling?

Gurgling noises often emanate from air bubbles trapped in the system or a poorly configured drain line. If you hear these noises, Reverse Osmosis System troubleshooting can guide you on releasing trapped air or adjusting the drain line, resolving the RO system noise.

How many years does an RO system last?

An adequately maintained Reverse Osmosis System can last between 10 to 15 years. One of the Advanced Watertek RO plants on a farm lasted 35 years. Specific components like filters and membranes may require more frequent replacement—typically every 6 to 12 months.
