Water filtration in Cremorne
Cremorne drinks what the rest of Sydney drinks: Sydney Water mains, monitored against the Australian Drinking Water Guidelines; safety is not the reason anyone here buys a filter. What residents notice is taste and consistency. In the walk-up blocks, water reaches your kitchen through shared risers that can be as old as the building, so the first glass of the morning may taste flat or metallic and a maintenance job elsewhere in the block can stir up a brief brown tinge. Others simply prefer to remove the chloramine note. Since about seven in ten Cremorne homes are flats sharing a meter, under-sink filtration is the practical answer for most; the houses and semis around Cranbrook Avenue and Murdoch Street can take a whole-house unit as well.
Fitting a filter counts as plumbing work under NSW law, and plumbing is licensed from the first dollar, so the people we match for Cremorne are licensed plumbers; we look each licence up on the public register ourselves. Every product used is WaterMark-certified, and AS/NZS 3500 governs how it goes in. In a unit, the plumber measures the cabinet first, because the waste trap, dishwasher hose and sometimes a disposal unit compete for space, then fits a sediment and carbon unit, or a compact reverse osmosis system where fluoride reduction is wanted, with its own tap. Where the connection would involve a shared stop valve or riser, possibly common property, the plumber will ask you to confirm the strata manager's position before starting.
Let us know unit or house, what you dislike in the tap water, and whether you are after a drinking tap or whole-home treatment. The job goes to vetted licensed plumbers with filter installs in Cremorne behind them; one will ask for a photo under the sink, then send a written quote listing product, certification and the cartridge schedule. No fee applies to homeowners and nothing obliges you to proceed. Low pressure on upper floors of older blocks can limit some systems, so the plumber may test the tap before recommending a model, and will say if a booster is needed.

Frequently asked questions
Water that has stood overnight in older building pipework picks up a flat or metallic taste. Running the cold tap briefly clears it. An under-sink filter improves taste and catches fine sediment from the risers, and it does so without touching the building's shared plumbing.
Not usually, when the plumber stays on the cold line within your own cabinet. Where the plumber has to work on a shared stop valve or riser, which may belong to the scheme, the owners corporation's approval is needed. A short note to the strata manager before the job avoids argument later.
Often, with a compact or tankless model, which is why the plumber measures first. Reverse osmosis needs a drain connection and adequate pressure, and upper floors in older blocks can be short on pressure. If space or pressure rule it out, a slim carbon system is the alternative.
If the house has its own meter and a suitable spot near where the supply enters, yes. A semi that shares a meter is better served at the sink. The plumber checks pressure and the pipe route first, and in a conservation area places any external housing out of view from the street.
