Nollet RO offers a complete supply-and-install service. We provide the RO system, all associated filtration components, plumbing fittings, and post-installation support as a unified package. We also offer installation-only services if you have already purchased an RO unit and need professional commissioning. In both cases, we ensure the final setup meets our quality and performance standards before completion.

Bore water in Iyyapakkam often contains elevated turbidity, iron, and hardness. A properly designed pre-treatment train for bore water typically includes a sediment filter (to remove suspended particles), an iron removal filter (if iron exceeds 0.3 mg/L), a softener (if hardness is high), and an activated carbon filter (to remove chlorine if present). Nollet RO’s water analysis determines exactly which pre-treatment stages are necessary before installing the RO membrane unit.

RO membranes require a minimum operating pressure — typically 40–60 PSI — to function correctly. In many residential areas of Iyyapakkam, municipal supply pressure may be insufficient during off-peak hours, and bore water supplied from overhead tanks naturally has low pressure. Nollet RO checks the inlet pressure during the site visit and includes a booster pump in the installation where needed, ensuring consistent performance regardless of supply pressure fluctuations.

Yes. For apartment blocks and multi-story residential buildings in Iyyapakkam, Nollet RO designs centralised RO systems that are installed in utility rooms, pump rooms, or terrace enclosures. The purified water is then distributed through dedicated food-grade pipelines to individual floors or flats. We conduct a structural assessment of the installation space and design the layout to minimise pressure drop across floors.

Our Annual Maintenance Contract for Iyyapakkam installations covers scheduled pre-filter cartridge replacements, membrane performance checks, UV lamp inspection and replacement, output TDS verification, pump pressure calibration, and priority response for breakdowns. AMC plans are available for both systems we install and those originally installed by third parties. Contact us for a plan customised to your system type and usage volume.

For housing colonies or gated communities with more than 10 units, a centralised RO system is significantly more cost-effective than installing individual units in each flat. A single commercial RO plant with adequate capacity, centralised maintenance, and distribution plumbing reduces per-unit investment, simplifies servicing, and delivers uniform water quality to all residents. Nollet RO has experience designing and commissioning centralised systems for apartment communities across Chennai’s western suburbs.

Signs that your RO system needs attention include a noticeable increase in output TDS (measured with a TDS meter), significantly reduced flow rate, unusual taste or odor in the purified water, leaks at connections, or the system running continuously without shutting off. A Nollet RO technician can assess your existing system and determine whether a filter replacement, membrane swap, or full system upgrade is the most cost-effective solution.
