How Often Should You Service Your RO in Delhi NCR?

Most RO purifiers in Delhi NCR should be checked every 3 to 6 months. The right timing depends on inlet-water TDS, sediment, daily use, filter condition, and whether your supply changes between municipal and borewell water.

A timely check helps identify a dirty pre-filter, falling water flow, leakage, unusual TDS, or pump noise before the purifier stops working. It does not mean every filter or membrane must be replaced at each visit.

Recommended RO service frequency

For a home using municipal water with moderate daily use, a check closer to every six months may be enough. Homes with high-TDS groundwater, visible sediment, heavy family use, or frequent supply changes may benefit from a check closer to every three months.

• Every 3 months: useful for high-TDS or sediment-heavy water, borewell supply, and heavy daily usage.
• Every 4 to 6 months: practical for many regularly used home RO purifiers.
• Earlier than scheduled: recommended when flow, taste, smell, sound, leakage, or purified-water TDS changes.

Manufacturer guidance and the purifier's service history should also be considered. A purifier that has been unused for several weeks should be inspected and cleaned before regular use resumes.

Why Delhi NCR water conditions matter

Water conditions can differ between neighbourhoods and even between nearby buildings in Delhi, Gurgaon, Noida, Faridabad, and Ghaziabad. One home may receive mostly municipal water while another relies on a borewell or tanker supply.

Sediment can choke the pre-filter faster. Higher inlet TDS puts more demand on the membrane. Seasonal or source changes can also affect taste and the difference between inlet and purified-water TDS. This is why service timing should follow actual purifier performance, not only a fixed calendar date.

Signs your RO needs service

• The storage tank takes much longer than usual to fill.
• Purified water flow becomes slow or uneven.
• Water taste or smell changes.
• Purified-water TDS rises or changes significantly.
• The purifier leaks, vibrates, or makes a new sound.
• The pump runs for unusually long periods.
• The sediment filter looks heavily loaded with dirt.

If your main issue is weak output, read the guide to slow RO water flow and indicative repair cost.

What should be checked during service?

A useful routine service visit should focus on diagnosis and condition, not automatic replacement. The technician may check:

• Inlet water supply and pressure.
• Pre-filter and sediment/carbon filter condition.
• Purified-water flow and storage tank filling.
• Inlet and purified-water TDS readings.
• Pump, valves, pipes, tap, and visible leakage.
• Storage tank hygiene and purifier cleanliness.
• Membrane performance and compatibility.

Visit/service charges and warranty

The Online Visit/Service Charge is ₹99. The Pay After Service Visit Charge is ₹249. Repair parts, filters, membrane, fittings, and non-standard work are charged separately after technician inspection and customer approval. Prices inclusive of GST, with GST invoice support.

RO Service Wala provides a 60 Days Service Warranty. There is no visit/service charge for the same reported problem within warranty terms. Parts, filters, membrane, fittings, consumables, or replacements are charged separately unless covered by invoice or plan terms. A different or unrelated problem may require a new visit/service charge.

When to call a technician

Book professional support when a performance change continues after confirming the inlet valve and building water supply are normal. A technician should also inspect the purifier when electrical work, pump diagnosis, internal leakage, filter opening, or membrane testing may be needed.

For routine maintenance, visit the RO service page. If your purifier needs repeated maintenance through the year, compare the coverage on the RO AMC plans page. You can also contact RO Service Wala before booking.
