In a city like Coimbatore, where all members in most families are dependent upon borewell and tanker water, a Reverse Osmosis (RO) water purifier is not an extra—it’s essential. With growing concerns about water quality, mineral levels, and contamination, RO purifiers are recommended to provide pure, safe, and tasty water.
Why Regular RO Servicing Is Important
With time, filters and membranes of your RO purifier get clogged with sediment, dirt, and dissolved contaminants. If they are not serviced or replaced on time, you stand to lose:
• Contaminated drinking water
• Decreased flow or pressure of water
• Bad taste and odor
• Membrane damage
• Increased electricity consumption
• Expensive repairs or the entire unit’s replacement
In essence, not servicing it stands to compromise your health as well as your investment.
How Often Should You Service Your RO Purifier?
There is no one-size-all, but the following is a general rule used by most brands and service personnel:
• Component Service Interval
• Sediment Filter 6–8 months
• Pre-Carbon Filter 6–8 months
• RO Membrane 12–18 months
• Post-Carbon Filter 12 months
• UV Lamp (if installed) 12 months
• Full System Maintenance Every 6 months (min)
Water Quality in Coimbatore: Why It Impacts Servicing Frequency
Coimbatore is largely reliant on:
• Borewell water in residential complexes
• Tanker supply in apartments
• Tap water from municipalities in some areas
All these supply sources are bound to have high TDS (Total Dissolved Solids), heavy metal, and other minerals like calcium and magnesium, which result in:
• Increased filter clogging
• Increased pressure drop in membrane
• Increased sediment and sludge in the pre-filter
• Scaling on internal components
Thus, compared to regions where the water is soft, individuals in Coimbatore generally have to service their RO systems more frequently—particularly in areas like Saravanampatti, Vadavalli, and Peelamedu where groundwater TDS is generally high.
Warning Signs Your RO Water Purifier Needs Servicing
Need assistance when to schedule a service visit? Look out for these frequent warning signs:
1. Change in Taste or Odor of Water
If your water is salty, bitter, or chlorinated, then the filters are dirty or spent.
2. Lower Water Flow
Weak or watery flow from your purifier typically means dirty filters or membrane damage.
3. Water Leakage
Leakage around the faucet, filter housing, or tank can be caused by loose fittings or spent parts.
4. Strange Sounds
Gurgling, hissing, or vibrating sounds may mean pressure imbalance, faulty valves, or air blockage.
5. Reminder for Filter Change (in Smart Models)
Most new filters have a built-in indicator light or app alerts to remind you that the filters must be replaced.
Advantages of RO Service on Time
Following are the benefits of timely service of your RO purifier:
• Provides you with pure and healthy drinking water
• Avoids health problems due to dirty water
• Saves you money in repair or replacement costs
• Extends the life of your RO system
• Conserves electricity
• Maintains water pressure and taste steady
RO Servicing Cost in Coimbatore
RO servicing in Coimbatore costs between ₹400 to ₹800 for a standard maintenance check. Replacement items such as filters or membranes are additional.
Here’s an approximate breakdown:
• Service/PartApprox. Cost (INR)
• Annual Maintenance Contract (AMC)₹1500 – ₹3000
• Sediment/Carbon Filter Set₹500 – ₹1000
• RO Membrane₹1200 – ₹2500
• UV Lamp₹500 – ₹800
Do You Need to Take AMC (Annual Maintenance Contract)?
If you’d like to have peace of mind, an AMC is the solution. It typically involves:
• Scheduled regular visits
• Endless emergency assistance
• Free filter replacement (in some plans)
• Priority service by specialists
For the families that use the RO daily, an AMC can save up to 25% compared to pay-per-visit maintenance.
Hacks to Extend the Life of Your RO Purifier
• Servicing it every 6 months even when it seems to be in good shape.
• Check for water quality with TDS meters on a monthly basis.
• Do not attempt to replace the filter unless you are a professionally trained technician.
• Clean the storage tank every 3 months to avoid algae and biofilm.
• Store the purifier in a dry, shaded area out of dust and heat.
