FAQs
What contaminants will your Cowan filtration systems remove from my tap water?
Our advanced multi-stage units are engineered to target the full spectrum of common Australian water contaminants, including chlorine and chloramine, rust and sediment down to 1 micron, heavy metals such as lead, mercury and copper, agricultural pesticides and herbicides, volatile organic compounds (VOCs), micro-plastics, cysts like Giardia and Cryptosporidium, and up to 99.99 % of bacteria and viruses. The result is water that looks, smells and tastes noticeably cleaner while meeting or exceeding the Australian Drinking Water Guidelines.
How does the technology work inside your state-of-the-art filtration systems?
We combine several proven stages in one compact, under-sink or whole-house package: 1) A high-capacity spun-polypropylene sediment cartridge screens out dirt and rust. 2) A catalytic activated-carbon block adsorbs chlorine, chloramine, VOCs and bad tastes. 3) A precision reverse-osmosis (RO) membrane removes dissolved salts, heavy metals and fluoride to 0.0001 micron. 4) Optional UV-C sterilisation neutralises any remaining microorganisms. 5) A final remineralisation cartridge polishes the water with healthy calcium and magnesium for balanced pH. Each stage is optimised so you enjoy pure, great-tasting water straight from your Cowan tap.
What maintenance is needed and how often should I replace filters?
Regular maintenance is quick and tool-free. Sediment pre-filters should be changed every 6 months. Carbon blocks typically last 9–12 months. The RO membrane has a life of 2–3 years, and the UV lamp should be replaced annually to maintain full sterilisation strength. Actual intervals depend on your household’s water usage and the incoming mains quality; our systems have built-in pressure gauges and optional TDS monitors to tell you exactly when service is due. We also offer affordable scheduled filter-change programs for Cowan residents.
Will installing a filtration system reduce my household water pressure?
Our plumbing-grade manifolds are designed for Australian mains pressure (350–500 kPa) and cause only a negligible 5–10 % drop, which most users never notice. For homes on the lower end of the pressure range or with multiple bathrooms, we can integrate a quiet, energy-efficient booster pump to keep showers and appliances running at full flow. Pressure testing is included in every Cowan installation to guarantee optimum performance.
Are your filtration products certified and safe for use in NSW?
Yes. All components carry WaterMark certification for legal installation in Australia and comply with NSF/ANSI Standards 42 (taste & odour), 53 (health effects) and 58 (reverse osmosis). The UV modules meet NSF 55 Class A disinfection requirements. Housing materials are BPA-free, food-grade plastics or 304 stainless steel. Our systems are backed by a 10-year structural warranty and full public-liability insurance, giving Cowan homeowners complete peace of mind.
What does the installation process involve and how long will it take?
After a free on-site water assessment, a licensed local plumber schedules your installation. Under-sink drinking-water units take about 90 minutes, while whole-of-house systems usually require 2–3 hours. We mount the filters, connect to the mains line, add an independent designer tap if desired, and thoroughly flush and pressure-test the system. No council approval is needed, and we remove all packaging and old filters. Service coverage includes Cowan, Berowra Heights and the wider Northern Sydney region.
