Build & operation

Water first passes the prefilters (sediment then activated carbon) trapping particles, chlorine and tastes. It then flows under pressure through the reverse-osmosis membrane, which passes only water molecules and sends contaminants to drain. A polishing cartridge finally refines taste before the dedicated faucet. The pressure tank (or direct flow) makes water available immediately.

Installation & maintenance

Reverse-osmosis system for tap water, fitted under the sink with the supplied kit (supply, tubing, quick fittings, dedicated faucet). Ensure sufficient feed pressure (or choose the booster-pump version). Replace prefilter cartridges once or twice a year and the membrane every 2–3 years depending on water quality. Photos non-contractual.
