Frequently Asked Questions

Standard units produce about 3 litres of reject water per litre of pure water. In our pumped and tankless models this falls to 1:1. Reject water can be used for cleaning and irrigation.

Under-sink units are installed in 1.5 to 2 hours. A whole-house inlet filter and softener take three to five hours. Industrial systems are commissioned in 2 to 12 weeks depending on capacity.

Sediment filters are replaced at six months, carbon filters at 6-12 months and the RO membrane at 24-36 months. The device display and SMS reminder tell you when maintenance is due.

Home units have a three-year warranty and industrial systems two years. Consumables such as filters and membranes are outside warranty; we also commit to ten years of spare-part supply.

A first analysis for iron, manganese, hardness and microbiology is needed. Typically a sand/carbon inlet filter, softener and UV sterilisation are used together; reverse osmosis is added for drinking water.

Choose 'On-site Water Analysis' in our online booking system. A specialist visits your home, measures TDS, hardness, chlorine and pH, shares the results instantly and offers advice. The basic analysis for homes is free.

The Water Pollution Control Regulation sets limits by sector and discharge point. Pretreatment is required for businesses connected to an industrial zone and full treatment for discharge to a receiving environment. We offer a survey service for compliance.

Softening removes hardness and raises sodium very slightly. For drinking water we suggest a separate reverse osmosis unit in the kitchen, protecting plumbing and improving drinking water quality.

Our 36 service points are in 24 provinces. The current list and map are on the Service Points page; we aim for same-day service in major cities and next-day elsewhere.
