The Bureau of Indian Standards (BIS) under IS 10500:2012 specifies an acceptable total hardness limit of 200 mg/L (as calcium carbonate) for drinking water, with a permissible limit of 600 mg/L where no alternative source is available. Many water samples collected from Kundrathur bore wells and open wells exceed the 200 mg/L threshold, making treatment advisable for regular domestic use.

Water softened using ion exchange replaces calcium and magnesium with a small quantity of sodium. For most people, this is completely safe, but individuals on a sodium-restricted diet may prefer to connect the drinking water tap directly to an RO system placed after the softener. Nollet RO can configure a combined system where the softener treats water for all utility purposes while a separate RO unit handles drinking water, giving you the best of both solutions.

Salt consumption depends on your water’s hardness level and daily usage volume. A typical household in Kundrathur may need salt replenishment every four to eight weeks. Nollet RO provides usage guidance based on your specific water report and system capacity. Under our AMC plan, our technician visits periodically to check salt levels, verify regeneration cycles, and confirm output quality, so you never have to monitor this yourself.

A correctly sized water softener causes a negligible pressure drop. In fact, over time, soft water actually improves pressure delivery by preventing limescale buildup inside pipes that progressively reduces flow in untreated systems. Nollet RO engineers every installation with pressure drop calculations in mind, ensuring the system capacity matches your home’s peak water demand without affecting output pressure at any fixture.

Absolutely. Nollet RO regularly installs water softeners for apartment complexes, gated communities, and multi-unit residential buildings across Chennai and its western suburbs, including Kundrathur. For buildings with a shared overhead tank or pump room, we install a centralised softener at the inlet that treats water for every flat simultaneously. We size the system based on the total number of residents and peak hourly demand.

A water softener targets specific minerals, primarily calcium and magnesium, using ion exchange. It does not significantly reduce TDS or remove bacteria. An RO system removes a broad range of dissolved solids, heavy metals, and microorganisms, but can be damaged by hard water if not preceded by a softener. For the best water quality outcome, Nollet RO recommends a water softener at the main inlet, followed by an RO system at the point of consumption, each doing what it is designed to do most effectively.

The cost varies based on the resin tank capacity required, the degree of automation, and the complexity of your installation point. Compact domestic systems start at an accessible price point, while larger systems for apartment buildings or commercial spaces are quoted based on flow rate and site requirements.
