Water Purifier Brands We Service

Typical filtration stages

Commonly a multi-stage RO+UV+UF setup with a TDS controller on many models, to balance purification with essential mineral retention.

Common issues we see

Membrane fouling from high-TDS input water, pump/motor wear, and clogged sediment or carbon cartridges are the most frequent call-outs.

Typical service interval

Sediment and carbon filters typically need checking every 4–6 months; the RO membrane commonly lasts 12–24 months depending on local water quality.

Typical filtration stages

Widely uses RO+UV combination purification, with some models adding an active copper or e-boiling stage.

Common issues we see

UV lamp expiry (UV lamps generally have a rated life and need periodic replacement), storage tank float valve issues, and slow flow from a choked pre-filter are common.

Typical service interval

Pre-filter cartridges are typically checked every 4–6 months; UV lamps are generally replaced on a yearly cycle regardless of visible symptoms.

Typical filtration stages

RO-based systems, often marketed with a higher save-water-ratio (SVR) design that reduces reject water compared to older RO technology.

Common issues we see

SVR valve or pump wear over time, membrane scaling in hard-water areas, and TDS drift in output water are the issues technicians see most.

Typical service interval

Pre-filters are commonly checked every 4–6 months, with membrane condition assessed annually or sooner if TDS testing shows a rise.

Typical filtration stages

Product range spans non-electric gravity-based purifiers to RO+UV electric systems, depending on the specific model in your home.

Common issues we see

For gravity models, a spent germ-kill/candle cartridge is the most common issue; for RO+UV models, pump and UV lamp wear are typical.

Typical service interval

Gravity-model cartridges are usually rated by litres purified (check the unit's indicator); RO+UV models follow a similar 4–6 month filter, 12–18 month membrane pattern.

Typical filtration stages

Typically a multi-stage RO+UV+UF system, with some models emphasising mineral retention alongside purification.

Common issues we see

Rising output TDS signalling membrane wear, pump noise, and display/indicator faults are the most reported issues.

Typical service interval

Sediment and carbon filters are commonly checked every 4–6 months, with the membrane assessed annually based on TDS test results.

Typical filtration stages

Generally an RO+UV+UF multi-stage setup, with digital TDS/flow display on several models.

Common issues we see

PCB or display faults, pump failure, and leakage from aging internal fittings are common as units age.

Typical service interval

Filter checks every 4–6 months and an annual membrane assessment is a reasonable default, adjusted to your local water quality.

Typical filtration stages

Range includes both non-electric gravity purifiers (with a germkill processor stage) and RO+UV electric models.

Common issues we see

Gravity models commonly need germkill cartridge replacement once their rated capacity is reached; RO models see typical membrane and pump wear.

Typical service interval

Gravity cartridges are generally rated for a fixed number of litres (check the unit's counter); RO membranes commonly last 12–18 months depending on usage.
