Whole House Water Filter Installation
Whole House Water Filter Installation – Quick Summary
A whole house water filter is installed at the point where water enters your property, so every tap, shower, appliance, and hot water system gets the same filtered supply. Transform Water supplies and installs whole-house systems across Sydney for homes on mains, rainwater tank, bore, or combined sources. One installation protects your entire property, your plumbing, your appliances, and everyone in the house.
Whole House Water Filter Installation Sydney Wide
Every tap in your home should deliver clean, safe water, not just the one you’ve put a jug filter under. A whole house water filtration system treats water at the point it enters your property, so every shower, tap, washing machine and hot water system gets the same filtered supply.
At Transform Water, we supply and install whole house water filtration systems that treat every drop of water entering your property. Whether your home runs on mains water, rainwater tanks, bore water or a combination of sources. Our one system supply, installed once, protecting the whole property.
What Is a Whole House Water Filter?
A whole house water filter (also known as a point-of-entry system) is installed at the main water line where water first enters your property. Unlike a single tap filter, it treats all the water in your home before it reaches your kitchen, bathrooms, laundry, hot water system and outdoor taps.
That means:
- Filtered drinking and cooking water from every tap
- Cleaner water for showering and bathing – gentler on skin and hair
- Protection for hot water systems, dishwashers, washing machines and plumbing from sediment and scale
- Removal of chlorine taste and odour throughout the entire home
- Safer water from rainwater tanks and bore supplies
What a Whole House Filter Actually Protects
| Area of Your Home | Without a Whole House Filter | With a Whole House Filter |
|---|---|---|
| Kitchen taps | Chlorine taste and odour, sediment, potential contaminants from tank | Clean, filtered drinking and cooking water from every tap |
| Showers and bathrooms | Chlorine and sediment on skin and hair, dryness and irritation | Gentler water for bathing, reduced skin and hair dryness |
| Hot water system | Sediment build-up, scale, reduced system lifespan | Protected heat exchanger, extended system life |
| Dishwasher and washing machine | Scale build-up on heating elements, reduced appliance lifespan | Cleaner rinse cycles, protected appliance internals |
| Outdoor taps | Unfiltered supply reaching garden, pets, and external uses | Filtered supply throughout the entire property |
We Supply and Install the Complete System
Every property is different, which is why we handle the entire process in-house, from the initial water assessment through supply, installation and ongoing servicing.
We Assess Your Water
1
We start by understanding your water source and what’s in it. If you’re on tank or bore water, we can carry out water treatment and testing to identify sediment, bacteria, hardness, iron, tannins or other contaminants before we recommend anything.
We Supply & Install
2
Based on your water quality, household needs, and available space, we supply and install the right filtration setup at the main point of entry, so your water is treated before it flows through the rest of your property.
We Service and Maintain It
3
Filters need periodic replacement and UV lamps need annual changes to keep performing. We offer scheduled filter servicing and maintenance so your system keeps protecting your home year after year.
What’s Included in Our Installation Service
We assess your water source and usage before recommending a system, then handle the full installation.
Our service includes:
- Testing your water source, mains, tank, or bore, to identify what needs filtering
- Recommending the right combination of sediment, carbon, UV or softening stages
- Installing the system at your property’s main water entry point
- Connecting and pressure-testing the full setup
- Confirming water flow and quality at multiple taps once installed
- Leaving the installation area clean and explaining your maintenance schedule
What Goes Into a Whole House System
Most whole house installations combine two or more of these stages, matched to your water source and what you’re trying to remove. Read our full guide to types of water filters for more detail on each.
Sediment Pre-Filters
1
First stage of protection. Removes dirt, rust and sand before water reaches the rest of the system or your plumbing.
Best For – Rainwater tanks & bore water
UV Purification
2
Disables bacteria and viruses using UV light, with no added chemicals. Common on tank and bore-fed properties.
Best For – Microbial protection
Carbon Filter
3
This helps improve taste and smell by reducing chlorine, chemicals, and odours.
Best for:
Mains water, chlorine smell, bad taste, and everyday household use.
Water Softening
4
Ion exchange softening reduces calcium and magnesium, cutting limescale build-up in pipes and hot water systems.
Best For – Hard water areas
Multi-Stage Systems
5
Combines sediment, carbon and UV (and softening where needed) into one point-of-entry unit for complete coverage.
Best For – Most whole house installs
Suited to Mains, Tank & Bore Water
The right whole house setup depends on your water source.
Mains / town water – Mains water properties usually need sediment and carbon filtration to deal with chlorine, taste and minor sediment.
Rainwater tanks – Rainwater tank properties typically need sediment filtration plus UV purification to manage microbial risk. See our rainwater tank filtration installation page for tank-specific setups.
Bore water – Bore water properties often need the fullest combination, sediment, carbon, UV and sometimes softening, depending on what’s in the ground.
Is a Whole House Filter Right for Your Property?
A whole house filter is worth considering if any of the following apply to your property:
- You rely on a rainwater tank for drinking or cooking water and want the whole house covered, not just one tap.
- Your mains water has a noticeable chlorine smell or taste that a jug filter alone does not resolve.
- You are on bore water and need treatment across the full property including bathrooms and laundry.
- You have young children, elderly household members, or people with compromised immunity who need consistent water quality throughout the home.
- You want to protect your hot water system, dishwasher, and washing machine from sediment and scale build-up.
If you are unsure whether your property needs a whole-house system or a point-of-use filter at one tap, a water lab test is the fastest way to get a clear answer. We carry out testing before recommending any system.
Why Choose Transform Water
- Water source expertise: We work across mains, rainwater tank and bore-fed properties, not just one type of setup.
- Right-sized systems: We recommend filtration based on your actual water and usage, not a one-size-fits-all package.
- Quality components: We install using reliable, tested filtration hardware built to last.
- Ongoing support: Once installed, we’re on hand for servicing and filter replacement so the system keeps performing.
Why Trust Transform Water to Install Your Whole House Filter?
Installing a point-of-entry system is a licensed plumbing job in New South Wales. Our team holds full NSW plumbing licences and completes whole-house filter installations to Australian Standards, ensuring the system is safe, compliant, and correctly integrated with your existing pipework.
We size every system to your household’s actual water demand, not a generic estimate. We factor in the number of occupants, daily usage patterns, the water source type, and the results of a water quality test before specifying any components. An undersized system leads to pressure problems. An oversized one wastes money on cartridge replacements. We get the sizing right the first time.
We have installed whole-house systems across Sydney for over a decade, covering mains-connected homes, rainwater tank properties, rural acreages on bore water, and properties running on a combination of sources.

Frequently Asked Questions
Will a whole house water filter reduce my water pressure?
A correctly sized whole house filter has minimal impact on water pressure under normal household flow conditions. Pressure loss is almost always caused by an undersized filter housing, a cartridge that is overdue for replacement, or a system that was not sized to match the property’s actual peak flow demand. We size every system to your household’s usage before installation to prevent this.
How much does a whole house water filter installation cost in Sydney?
Cost depends on the number of filtration stages required, the components specified, and the complexity of connecting to your main water line. A basic two-stage sediment and carbon system will cost less than a full multi-stage setup with UV sterilisation. We provide a fixed-price quote after assessing your property and reviewing your water test results, so there are no surprises on the day.
How often do whole house filter cartridges need to be replaced?
Sediment cartridges in most whole-house systems need replacement every 3 to 6 months and carbon cartridges every 6 to 12 months, depending on your water source and household usage volume. UV lamps require annual replacement regardless of usage. We can schedule recurring maintenance visits so replacements are never missed and your system continues to perform correctly between service intervals.
Can a whole house filter work with both mains and rainwater tank supply?
Yes. Many Sydney homes run on a combination of mains and rainwater tank supply. We design dual-source systems that treat both inputs appropriately, since mains water and rainwater tank water carry different contaminant profiles and require different filtration stages. A single point-of-entry system can be designed to handle both sources safely.
What does a whole house water filter actually remove?
Depending on the filtration stages installed, a whole house system can remove sediment and particles, chlorine and chloramines, volatile organic compounds, pesticides and herbicides, heavy metals, and with UV sterilisation, bacteria, viruses, and protozoa. The exact removal performance depends on the filter media and micron rating specified, which is why we carry out a water test before designing any system.
Is a whole house filter the same as a water softener?
No. A whole house filter removes contaminants, particles, chemicals, and biological threats. A water softener specifically targets water hardness by replacing calcium and magnesium ions with sodium or potassium through an ion exchange process. The two serve different purposes. Some properties, particularly those on bore water with high mineral content, may benefit from both. We assess your water quality and recommend the appropriate solution for your specific situation.
Where is a whole house water filter installed?
A whole house filter is installed at the point where the main water supply enters your property, before the water reaches any internal distribution pipes. This is typically near the water meter or at the pressure reduction valve location. Installing at this point ensures every tap, appliance, and fixture in the property receives filtered water. Our licensed plumbers handle the connection and ensure it is compliant with NSW plumbing standards.
Can I install a whole house filter myself or does it need a plumber?
In NSW, connecting any filtration system to the mains water supply requires a licensed plumber. DIY connections to potable water supply lines are illegal and can void your home insurance. Beyond compliance, a poorly installed point-of-entry system can introduce contamination, cause pressure problems, or fail at the connection under mains pressure. Our team handles the full installation including all required compliance documentation.
How long does a whole house water filter installation take?
Most whole house filter installations are completed in a single visit of two to four hours for a straightforward mains connection. More complex setups involving multiple stages, pump integration, or dual-source configuration may take longer. We assess your property before booking and give you an accurate timeframe so the installation does not disrupt your household more than necessary.
What is the difference between a whole house filter and an under-sink filter?
An under-sink filter treats water at a single point of use, typically one kitchen tap. It is effective for drinking and cooking water from that one outlet but does nothing for the rest of the house. A whole house filter treats all the water entering the property at the source, so every tap, shower, hot water system, and appliance receives filtered water. For families concerned about water quality throughout the home, a whole house system provides complete coverage that an under-sink unit cannot.
