If your RO water purifier has started making loud or strange noises, it’s usually a sign that something is off internally. A humming sound, vibrating noise, or even a clicking or gurgling sound—none of these are normal, especially if they appear suddenly.
Whether you’re using a Kent, Aquaguard, or any other popular RO system, persistent noise is more than just annoying. It’s a warning sign that your purifier may need urgent attention.
In this blog, we’ll explore the most common reasons your RO is making noise, what each type of sound indicates, and when it’s time to search for a water purifier service near you or contact your nearest water purifier shop.
Is Noise Normal in RO Water Purifiers?
To a certain extent, yes. A mild humming sound during water purification is expected, especially when the RO booster pump is running. However, if your system is suddenly louder than usual or making irregular or harsh noises, it could mean:
- Loose parts
- Blockages in filters
- Electrical faults
- Worn-out components
Ignoring these noises could lead to bigger issues like system failure or water leakage. That’s why it’s essential to get timely help from a water purifier service in Bangalore or look for Kent RO service near me if you’re using Kent models.
Common Noises and What They Mean
Let’s break down different noises and what could be causing them:
1. Humming or Buzzing Sound
A constant humming is usually caused by the RO booster pump. While mild humming is expected, a loud buzz could mean the pump is struggling due to:
- Low input water pressure
- Clogged pre-filter
- Worn-out motor
If this persists, it’s time to schedule a water purifier service near me to inspect the pump and filters.
2. Clicking or Tapping Sound
Clicking sounds are often caused by the solenoid valve or auto shut-off valve inside the unit. These valves control water flow and pressure, and when they malfunction or become blocked, they may click repeatedly.
Technicians from a water purifier shop near you can clean or replace these valves as part of standard water filter service.
3. Vibrating Sound
If your purifier vibrates loudly while working, it may be due to:
- A loose pump mounting
- An unstable surface
- Internal parts shaking due to clogged filters
Try placing your RO unit on a level, stable surface. If the noise continues, call for a Kent water purifier service or Aquaguard service near me to tighten or replace parts.
4. Gurgling or Bubbling Sound
Some RO systems discharge wastewater through a drain pipe. A soft gurgling sound may occur during this process, which is normal.
However, loud or constant gurgling could indicate:
- Blocked drain line
- Improper installation
- Excessive backpressure
This is especially common after a recent filter change or maintenance. A technician from your local water purifier service in Bangalore can check the drain setup and fix it.
5. Whining or High-Pitched Noise
A high-pitched whining sound could mean that the RO membrane is choked, and water is struggling to pass through it. This sound often appears just before a complete system failure.
If you’re experiencing this, search immediately for a Kent RO service near me or water purifier service near me to get the membrane checked and replaced if needed.
Common Reasons for RO Noise
Let’s look at some of the most common technical causes behind noisy RO systems:
| Cause | Noise Type | Solution |
| Clogged Pre-filter | Humming or buzzing | Replace pre-filter during service |
| Air Trapped in Filters | Gurgling or bubbling | Let system run for a few cycles |
| Loose Pump or Valve | Vibrating or clicking | Tighten or replace loose components |
| Old or Faulty Pump | High-pitched whine | Replace booster pump |
| Incorrect Installation | Any noise | Reinstall system correctly |
| High TDS or Pressure Variation | Random loud noises | Install pressure regulator |
What Can You Do at Home?
Here are a few things to try before booking a service:
- Check water pressure: Low pressure can overwork the pump.
- Reboot your system: Turn off the power and unplug for a few minutes.
- Let it run a few cycles: Sometimes air gets trapped in new filters and causes noise.
- Inspect the surface: Make sure the purifier is installed on a stable platform.
If none of these solve the issue, it’s time to contact a local expert by searching water purifier near me or reaching out to a trusted water purifier service in Bangalore.
When Should You Call a Technician?
If the noise:
- Started suddenly and won’t stop
- Gets louder over time
- Comes with no water flow
- Happens during and after purification
- Continues even when the unit is off
…then it’s time for a professional diagnosis.
