Cleaner Water Starts With Your Pipes, Not a Catalogue Pick
Filtered water is only as good as the system behind it, and the right choice depends on what your supply lines are carrying and how your household actually uses water. The team behind Normanhurst treats filtration as part of the whole supply system, tested and matched before anything is mounted under a sink.
Old Supply Lines Change the Filtration Story Here
Plenty of houses from the early and mid twentieth century around here still carry galvanised steel supply pipes, and rust plus scale shed into the water as those lines corrode from the inside.
Filtration therefore works harder in these homes than in a newer subdivision:
- Sediment loads run higher So cartridges exhaust faster than the box suggests.
- Pressure is already compromised By narrowed pipe bores, and the wrong micron rating strangles it further.
- The hardware has to be matched To what the pipework actually delivers, not to a showroom demo.
We test the water and the flow before recommending anything, because a filter sized for pristine town water will choke early on supply lines like these.
Filter Systems We Fit and Maintain
From a single drinking tap to filtration protecting the entire house, we install, service and replace water filter systems with compliant fittings, proper isolation and a setup you can actually live with:
Under-Sink Filtration
An under-sink filter connects to the cold supply through a dedicated isolation valve and benchtop faucet, giving the kitchen a constant supply of properly filtered water without cluttering the benchtop or slowing the sink's everyday routine.
Whole-House Filtration
A whole-house filter sits on the main cold supply right where it enters the home, protecting every tap, shower and appliance at once, which suits households wanting better water for bathing, laundry and cooking rather than drinking alone.
Cartridge Replacements and Servicing
Cartridges have finite lives, and a filter left too long starts releasing trapped sediment back into the water, so we set a replacement rhythm matched to your usage and keep the common cartridge types stocked on the van.
Water Quality Testing First
Before recommending any hardware we test what is actually coming through your taps, because sediment, taste and pressure complaints trace to genuinely different causes, and the right filter for one problem is often the wrong answer for another.
Filtration often sits alongside other kitchen work, and if the sink, waste or mixer needs attention at the same time, our kitchen plumbing team handles the whole job in one visit.
Renovated Kitchens on Original Pipework
The plateau setting shapes this work too. At roughly 169 metres on the Hornsby Plateau, with shale and rock underfoot, the weatherboard and double-brick homes built through the 1940s and 1960s in the family streets near St Stephen's Anglican Church often pair original supply lines with kitchens renovated decades later.
We plan every filter install around that mix:
- Where the isolation valve sits So a future cartridge change never means pulling half the cupboard apart.
- Whether the cold feed is shared With a dishwasher or fridge connection that also needs protecting.
- What the existing pipework will tolerate Because a filter bolted onto corroding lines treats the symptom while the cause keeps shedding.
Common Water Filter Problems
Most filtration complaints fall into a handful of patterns, and each has a straightforward fix once the real cause is identified:
Sediment That Keeps Coming Back
Water that runs cloudy or gritty in older homes usually means corroding galvanised pipework shedding particles, and a filter manages the symptom while we assess whether the supply lines underneath are the real source worth addressing.
Pressure Dropping After Fitting
A filter that chokes flow within weeks of installation has usually been matched to the wrong micron rating for the household's demand, and reselecting the cartridge or adding a bypass restores pressure without sacrificing water quality.
Neglected Cartridges and Bad Tastes
A filter nobody has serviced for years can make water taste worse than no filter at all, because exhausted media leach back what they captured, and a simple cartridge swap with a housing clean usually fixes it.
Why Fitting It Properly Matters
A filter is a small investment with a long tail, and the difference between a good install and a rushed one shows up over months, not days:
- Water you can trust A correctly matched, correctly serviced filter keeps sediment, taste and odour under control across the whole house, rather than shifting the problem from the glass to the pipes.
- Pressure that survives The right cartridge for your flow demand protects showers and taps downstream, while a mismatched one quietly strangles the whole household's supply.
- Pipework protected Filtration reduces the grit travelling through ageing fixtures, and where supply lines themselves are the culprit, our leak detection and pipe assessment work finds that out honestly.
How it works
Our Process, Step by Step
- 01
Call and tell us
Ring (02) 9072 0520 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Fit, flush and test
The agreed filter system is mounted securely, connected to the supply with compliant fittings and an isolation valve, then flushed and tested for flow and leaks while you are shown exactly how the cartridge change works.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.

Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Normanhurst works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Where a filter connects to outdoor lines, irrigation or anything with a cross-connection risk, our backflow testing service keeps the whole setup compliant as well as clean.

Good questions, straight answers
Water Filter Questions Normanhurst Locals Ask
Which water filter suits an older home?
Houses still running corroding galvanised supply lines often benefit most from a whole-house sediment filter, but we always test your actual water and flow first, because the wrong micron cartridge can drop pressure noticeably through the whole home.
How often should a filter cartridge be changed?
Most household cartridges need replacing every six to twelve months depending on usage and water quality, and we set a replacement date with you at installation so the filter never becomes the problem itself.
Can you add a filter to an existing kitchen tap?
Yes, we connect an under-sink system through a dedicated isolation valve and a separate benchtop faucet, which keeps your existing mixer working normally and avoids drilling anything unusual into stone or timber benchtops.
Is filtered water worth it in this area?
Many older homes around here still run galvanised steel supply pipes that affect taste and clarity, so filtration paired with an honest assessment of the pipework usually delivers a more lasting improvement than filters alone.
Do you install filters in units and apartments?
We do, choosing compact under-sink systems that suit the cupboard space and body corporate constraints of unit living, with the isolation valve and cartridge position arranged so future servicing stays quick and mess free.
How much does a water filter installation cost?
Every job receives a fixed written price before any work begins, and the call out and quote cost you nothing, so you will know the complete figure before deciding whether to go ahead.
