We handle installation of wall-mounted and under-sink RO systems, as well as complete replacement of old, damaged, or outdated units.
We bring all necessary tools and fittings. No extra trips needed.
Regular servicing is essential to keep your RO purifier performing at its best. We recommend a full service at least once every 6 months to maintain water quality and extend the life of your unit.
Our comprehensive service includes cleaning, inspection, testing, and minor adjustments — leaving your purifier fresh and fully functional.
Service duration: 45–90 minutes at your location.
Filters and membranes have a limited lifespan. Using them beyond their recommended replacement period can seriously degrade your water quality. We supply and install only genuine, certified replacement components.
Our technicians identify the exact filters your unit needs and replace them correctly — ensuring optimal performance after every replacement.
Membranes typically last 2–3 years; pre-filters every 3–6 months.
Our AMC plans take the hassle out of RO maintenance. Subscribe to a plan and we handle everything — scheduled servicing, priority support, and filter replacements — so you never have to worry about your water quality.
