For most residential systems in Valasaravakkam, a professional service inspection once a year is sufficient, provided the automatic backwash is running correctly on schedule. However, if your bore water has unusually high iron content above 3 mg per litre, more frequent inspections every six months are advisable to ensure the media is not depleting faster than expected. Nollet RO’s AMC plans are structured based on your specific water conditions.

The Annual Maintenance Contract covers scheduled service visits, water quality testing at each visit, backwash valve and timer inspection, media bed inspection, all routine labour charges, and priority response for emergency service calls. Replacement of worn components, such as multiport valve seals or minor fittings, is typically included. Major items such as full media replacement or vessel replacement are quoted separately with prior notice. The exact scope is detailed in the AMC agreement provided before signing.

A routine service visit for a residential iron removal system in Valasaravakkam typically takes between one and two hours. This includes the initial inspection, backwash cycle verification, valve checks, and output water quality testing. If media replacement is required, the visit may extend to three to four hours, depending on vessel size. For larger systems in apartment buildings or commercial premises, the service duration is estimated when the appointment is scheduled.

Yes. If your bore water iron levels have increased over time or your property’s water consumption has grown, Nollet RO can evaluate whether an upgrade is more cost-effective than replacement. Options include adding a second filter vessel in series, switching to higher-capacity media, adding an aeration stage, or installing a dosing system to improve oxidation before filtration. All upgrade decisions are based on a fresh water test and site assessment at your Valasaravakkam property.

Yes. Nollet RO accepts urgent service requests for situations such as system leaks, complete flow loss, or severely degraded water quality that cannot wait for a routine appointment. AMC clients receive priority scheduling for emergency visits. For non-AMC clients in Valasaravakkam, emergency visits are available subject to technician availability, and are confirmed within a few hours of the call being made to our service line at +91 96770 50885.

Yes. Nollet RO’s systems are configured to address both forms. Ferrous iron (dissolved, colourless) is first oxidised into ferric iron (insoluble, brownish precipitate) through an aeration or chemical oxidation stage. The ferric particles are then captured within the filter media layers. This two-stage approach ensures that even groundwater with high concentrations of dissolved iron — common in bore wells across Kundrathur — is treated comprehensively to meet safe output quality.

The cost varies based on flow rate capacity, type of filter media, automation level (manual vs. automatic backwash), and installation complexity. Entry-level domestic units typically start from a few thousand rupees, while larger industrial systems are priced higher based on specifications. Nollet RO provides a transparent, no-obligation quotation after conducting a free site assessment and water quality test. Contact us at +91 96770 50885 to arrange a visit.
