Water filtration in Hunters Hill
Hunters Hill is on Sydney Water mains like the rest of the city, and that water satisfies the Australian Drinking Water Guidelines; the houses are what differ. A sandstone cottage replumbed in stages can carry modern copper in the bathroom, old galvanised steel under the floor and a long service line from the street, so the first draw of the morning can run faintly yellow or leave grit in the aerator. Add the chloramine taste and you have the usual reasons for a filter. Houses on their own meter suit a whole-house sediment stage at the entry plus a carbon or reverse osmosis unit where you fill the kettle; townhouses and units near Gladesville Road suit under-sink systems.
NSW law reserves mains connections for licensed plumbers, requires WaterMark-listed products and holds the finished job to AS/NZS 3500, so the plumbers matched for Hunters Hill filter work are licensed and checked on the public register. Placement comes first here. Nothing is fixed to a visible sandstone wall or drilled into original fabric where an alternative exists; garages, sub-floors and laundries are preferred, and anything visible from the street on a listed house is discussed with Hunter's Hill Council first. Inside, an under-sink unit on your own cold line seldom raises a question. In a strata townhouse, work touching shared pipes needs the owners corporation's consent, confirmed before any pipe is cut.
Include a photo under the sink or of where the supply enters when you post, plus the age of the house if you know it and what you dislike about the water now. Vetted licensed plumbers already working in Hunters Hill, Woolwich and the Lane Cove area are matched to the job; each one contacts you to settle on a system and quote in writing. A good quote covers the equipment and its WaterMark approval, placement, isolation and bypass, the compliance certificate the plumber lodges, and when each cartridge falls due. If the plumber finds corroding pipe, expect them to say a short run of new pipe may do more than any cartridge.

Frequently asked questions
Not where there is an alternative, which there usually is: a garage, sub-floor, laundry or timber-framed service area. If a fixing into stone is unavoidable on a listed house, it is discussed with you first and, where visible, with council.
No. Same Sydney Water supply, same guidelines. The differences people notice come from the age and mix of pipework inside old houses and from water standing overnight in those pipes.
A sediment stage where the supply enters, to catch rust and grit, plus a kitchen filter, carbon or reverse osmosis, for taste. If the plumber finds badly corroded sections, replacing them comes before filtering.
Yes, usually an under-sink unit on your own cold line. If the complex is strata and the connection touches shared pipes or valves, the owners corporation needs to approve it, so check the by-laws before the plumber arrives.
