How Often Should You Service Your RO Water Purifier in Indore? – Complete Maintenance Guide
Your RO water purifier works silently around the clock, removing harmful chemicals, heavy metals, and bacteria from Indore's tap water. But like any hardworking appliance, it needs regular attention to perform at its best. Most homeowners in Indore service their RO too late — often only when the water flow stops or the taste changes. By that point, damage is already done and repair costs are higher.
This guide explains exactly how often you should service your RO, what a professional service includes, and how to spot problems early before they become expensive.
The Recommended RO Service Schedule for Indore
Indore's municipal water has above-average hardness and TDS levels (often 300–700 mg/L). This accelerates filter wear and membrane clogging compared to cities with softer water. Here is a practical maintenance calendar for Indore households:
| Maintenance Task | Recommended Frequency |
|---|---|
| Pre-sediment filter replacement | Every 3–4 months |
| Carbon (GAC/CTO) filter replacement | Every 6 months |
| RO membrane replacement | Every 1–2 years |
| Post-carbon / inline filter | Every 12 months |
| Storage tank cleaning | Every 6–12 months |
| Full professional service | At least once a year |
| TDS test of output water | Every 3 months |
💡 Quick Rule of Thumb
If your RO is used by a family of 4 in Indore, plan for at least one professional service per year and a full filter change every 12 months. Larger families or high-usage households should service every 6 months.
Warning Signs Your RO Needs Immediate Service
Don't wait for the annual calendar if you notice any of the following:
- Water output has reduced significantly — If it takes much longer than usual to fill a glass, your pre-filter or membrane is likely clogged.
- Purified water tastes different — A chlorine, earthy, or metallic taste indicates an expired carbon filter or contaminated tank.
- TDS of output water is above 100 mg/L — The RO membrane is no longer filtering effectively and needs replacement.
- Purifier runs continuously without shutting off — The auto shut-off valve or float valve may have failed.
- Visible slime, discolouration, or cloudiness — Bacterial growth in the tank or filters, requiring immediate professional attention.
- Unusual noise from the unit — Pump issues, pressure problems, or loose components.
⚠ Drinking Poorly Filtered Water Is a Health Risk
An expired RO membrane can allow heavy metals, fluoride, nitrates, and bacteria back into your drinking water. If your purifier hasn't been serviced in over 18 months, schedule a check immediately — don't wait for visible symptoms.
What Does a Professional RO Service Include?
When you book a professional RO service with Aqua Care RO, here is what our technician does during the visit:
- Complete inspection of all filters, membrane, pump, and fittings
- Cleaning of the purifier body and exposed components
- Backwashing of filters (removes accumulated sediment)
- Tank cleaning and sanitisation
- Check and tighten all water connections to prevent leaks
- Pump pressure check and adjustment if needed
- TDS and water quality test — both input and output water
- Recommendation report on components nearing expiry
Professional Service vs. DIY Maintenance
Some homeowners attempt to clean or replace filters themselves. While basic external cleaning is fine, here is why professional servicing is important:
- Membrane cleaning requires specialised tools — improper handling can damage the membrane, costing more to replace.
- Tank sanitisation needs food-grade disinfectants — household cleaners can contaminate your water supply.
- Pressure testing requires instruments — a technician can identify low inlet pressure or pump issues that aren't visible to the eye.
- Warranty protection — self-servicing can void manufacturer warranties on components.
✅ DIY Tip: Check Your TDS Every 3 Months
Purchase a basic TDS meter (₹150–₹300 online) and test your purified water regularly. If the output TDS rises above 100 mg/L, call a technician — don't wait for the taste to change.

Should You Get an AMC Plan?
An Annual Maintenance Contract (AMC) is the smartest investment for Indore households who want consistent water quality without the hassle of scheduling individual service calls. With AMC Plan 2 at ₹2,500/year, you get three scheduled services plus filter replacements included — saving approximately ₹1,500–₹2,000 compared to booking individually.
AMC is particularly recommended for families with young children, elderly members, or anyone with health conditions that make water quality especially important.
