3-Way Kitchen Mixers – Hot, Cold & Filtered Water in One Tap
A 3-way kitchen mixer combines normal hot water, normal cold water and dedicated filtered drinking water in one kitchen tap. It gives homeowners the convenience of under-sink water filtration without adding a second filter tap beside the main mixer.
JR Gas & Water supplies and installs 3-way filtered kitchen mixers throughout Greater Brisbane, the Gold Coast, Logan, Ipswich, Redlands, Moreton Bay, Scenic Rim and surrounding South East Queensland areas.
The current JR range includes Puretec Tripla and WFW 3-way mixers in high-loop, high-rise and pull-out designs, with finishes including chrome, brushed nickel, stainless steel, matte black, gunmetal and brushed gold.
The mixer is only one part of the setup. The filtration system installed below the sink determines what treatment the filtered-water outlet actually provides. A 3-way mixer should therefore be chosen together with the right under-sink filter rather than treating the tap itself as the filtration technology.
JR Installer Verdict: Choose the filtration system for the water treatment you want, then choose the 3-way mixer for the kitchen design and functionality you want. The tap delivers the filtered water; the filter underneath determines how that water is treated.
What Is a 3-Way Water Filter Mixer?
A 3-way mixer is a kitchen tap designed to deliver three water functions from one tap body:
Normal Hot Water
Hot water from the property's normal hot-water supply for washing, rinsing and general kitchen use.
Normal Cold Water
Unfiltered mains or household cold water for normal sink use.
Filtered Drinking Water
Water supplied through the dedicated filtration pathway from the compatible under-sink water filter.
This differs from connecting a normal mixer directly through a water filter, where all cold water used at the sink may pass through the drinking-water cartridge.
JR Installer Verdict: A proper 3-way setup keeps everyday sink water and dedicated filtered drinking water as separate functions. That means you are not unnecessarily using your filter cartridge every time you rinse a plate or run ordinary cold water.
How Does a 3-Way Kitchen Mixer Work?
A compatible 3-way mixer is designed with separate water pathways so filtered drinking water remains separate from normal mixer water through the intended tap configuration.
1. Hot Supply
The normal household hot-water line connects to the mixer for standard hot water operation.
2. Cold Supply
The standard cold-water supply feeds normal mixer operation and supplies the filtration system through the required connection.
3. Water Filter
A portion of the cold-water supply passes through the selected under-sink filtration system.
4. Filtered Water Line
Filtered water travels from the treatment system to the dedicated filtered water connection on the mixer.
5. Separate Control
The mixer uses a separate filtered-water control or operating function so the user can select filtered drinking water independently.
6. One Tap Body
Normal hot, cold and filtered-water functions are delivered through one finished kitchen fixture.
3-Way Mixer vs Separate Filter Tap
Both configurations can provide dedicated filtered drinking water. The main difference is how the filtered-water outlet is integrated into the kitchen.

Keeping an existing mixer |
JR Installer Verdict: If your existing kitchen mixer is good and there is an easy location for a filter tap, there may be no reason to replace it. If you want one clean fixture or cannot practically add another tap, a 3-way mixer becomes much more attractive.
Why Choose a 3-Way Filtered Kitchen Mixer?
One Kitchen Tap
Normal hot, cold and filtered drinking water are available without a separate filter tap beside the mixer.
Cleaner Sink Area
Reducing the number of visible fixtures creates a simpler and more integrated kitchen appearance.
Dedicated Filtered Water
Filtered water can be selected independently without filtering every litre of normal cold water used at the sink.
Good for Renovations
A 3-way mixer can be planned into the new kitchen before the benchtop and cabinetry are completed.
Good for Retrofits
Replacing the existing mixer can add filtered drinking water without creating a second visible tap.
More Finish Options
Modern 3-way mixers are available in finishes designed to coordinate with sinks, handles and other kitchen hardware.
3-Way Mixer vs Filtering the Existing Cold Kitchen Tap
Another possible configuration is to connect a water filter to the cold side of a normal mixer. That can work in selected installations, but it means normal cold-water use at the mixer also consumes filtered water.

Selected installations where tap replacement is not desired |
JR Installer Verdict: Filtering every litre of cold kitchen water can use cartridge capacity much faster. A 3-way mixer is usually the cleaner solution where you want filtered drinking water without filtering routine sink use.
3-Way Mixers & Stone Benchtops
A 3-way mixer can be particularly useful where a separate filtered-water tap cannot practically be added to the existing benchtop.
Rather than creating another penetration for a second tap, the existing kitchen mixer position can potentially be used for a compatible 3-way mixer, subject to the sink, benchtop and plumbing configuration.
Important: Benchtop modification should be assessed for the actual material and site. Engineered or natural stone should not simply be drilled onsite as though it were a timber or stainless-steel surface. Where an additional penetration is not appropriate, replacing the existing mixer with a 3-way mixer can provide a clean alternative.
JR Installer Verdict: If you have a stone benchtop and want filtered water, check whether the existing mixer position can accept a 3-way tap before planning another hole.
High-Loop, High-Rise & Pull-Out 3-Way Mixers
The filtered-water function is only one part of choosing the tap. The mixer still needs to work well as the main everyday kitchen fixture.
High-Loop Mixer
A curved high-loop spout provides a classic modern kitchen appearance and useful clearance above the sink.
High-Rise Mixer
A taller mixer design can suit larger sinks and kitchens wanting a more architectural tap profile.
Pull-Out Mixer
A pull-out spray head adds flexibility for sink cleaning, rinsing large items and everyday kitchen use while retaining the filtered-water function.
JR Installer Verdict: Do not choose a 3-way mixer only because you like the filtered-water function. It also becomes the tap you use all day for normal washing and rinsing, so spout height, reach and pull-out functionality still matter.
3-Way Mixer Finishes
The current JR range includes multiple finishes so a filtered mixer can be matched more closely to the sink, cabinet hardware and overall kitchen design.
Chrome
Classic bright finish suited to a wide range of kitchens and existing chrome fixtures.
Brushed Nickel
A softer metallic finish commonly chosen for contemporary kitchens.
Stainless Steel
Pairs naturally with stainless-steel sinks and many kitchen appliances.
Matte Black
Strong contrast for kitchens using black tapware, handles and accessories.
Gunmetal
A darker metallic option for modern kitchens wanting something between black and traditional stainless finishes.
Brushed Gold
A warmer premium finish suited to kitchens using brass or gold-toned hardware.
Puretec Tripla 3-Way Kitchen Mixers
Puretec Tripla is one of the main filtered-kitchen mixer ranges currently offered by JR Gas & Water. The range includes multiple mixer designs and finishes intended to combine ordinary kitchen use with a dedicated filtered drinking-water function.
A Tripla mixer can be paired with a compatible under-sink filtration system, with the actual water-treatment capability determined by the filter selected for the installation.
JR Installer Verdict: Tripla is the tap family, not the filtration specification. The same style of mixer can be paired with different filtration depending on the customer's water-treatment goal.
WFW 3-Way Water Filter Mixers
JR's current range also includes WFW 3-way mixers across high-loop, high-rise and pull-out designs. These provide another option for customers wanting a single hot, cold and filtered-water fixture.
As with any 3-way mixer, the under-sink filtration system should be chosen separately around the desired treatment performance.
JR Installer Verdict: Compare mixer design, finish and everyday tap functionality separately from filter performance. They are connected parts of the installation, but they do different jobs.
What Water Filter Works with a 3-Way Mixer?
A 3-way mixer can be paired with different point-of-use filtration systems, provided the filtration and tap configuration are compatible.
Single-Cartridge Filters
Compact option where a suitable cartridge provides the drinking-water treatment required.
Twin Water Filters
Two filtration stages can combine different media where each stage has a defined treatment function.
Reverse Osmosis
Selected 3-way tap arrangements can form part of a compatible RO installation where advanced drinking-water treatment is wanted.
Compare under-sink water filters →
JR Installer Verdict: Do not pick the filter from the tap. Decide what you want the water filter to do first, then make sure the chosen mixer and filtration system are compatible.
3-Way Mixer with Reverse Osmosis
Reverse osmosis is a specialised point-of-use filtration technology that can be paired with suitable drinking-water tap configurations where the system and mixer are compatible.
RO requires more than simply connecting another cartridge. The membrane, pre-filtration, product-water flow, reject-water drain and available cabinet space all need to be considered.
For that reason, customers wanting a 3-way mixer and reverse osmosis should select the RO system first and confirm the intended mixer configuration is suitable.
Compare reverse-osmosis water filters →
JR Installer Verdict: A 3-way mixer does not turn a standard cartridge filter into reverse osmosis. RO is the treatment technology underneath the sink; the mixer is how the treated water is delivered.
What Can the Filtered Water Reduce?
The answer depends on the filtration system connected to the 3-way mixer. The tap itself should not be used to make contaminant-reduction claims.
Chlorine, Taste & Odour
Suitable activated-carbon filtration is commonly used for chlorine-related taste and odour reduction.
Sediment & Particles
Physical filtration can reduce suspended material according to cartridge design and rating.
Specific Water Concerns
Where PFAS, fluoride or another specific substance matters, choose filtration with appropriate verified product performance.
Reverse Osmosis Treatment
RO can provide broader dissolved-substance reduction where that treatment technology is selected.
General Drinking Water
Quality under-sink cartridge filtration can provide a practical everyday drinking-water setup without requiring RO.
Product-Specific Claims
Always check the exact filtration cartridge or system where a particular reduction claim matters.
JR Installer Verdict: Specific concern, specific filter. A premium mixer does not automatically mean a premium level of filtration.
3-Way Mixer vs Boiling, Chilled & Sparkling Tap
These categories are often confused because both can provide filtered water through one premium kitchen fixture.
| Feature |

Compare boiling, chilled & sparkling systems →
JR Installer Verdict: If you simply want hot, cold and filtered drinking water, a 3-way mixer is a much simpler category than a powered HydroTap-style appliance.
3-Way Mixers for Kitchen Renovations
A kitchen renovation is an ideal time to plan a 3-way mixer because the filtered-water system, mixer location and cabinet space can all be considered before the benchtop and cabinetry are finished.
Choose the Mixer Early
Confirm the tap dimensions, finish and sink layout before the benchtop and backsplash details are finalised.
Plan Filter Space
Reserve practical cabinet space for the filtration equipment and future cartridge servicing.
Plan the Plumbing
Make sure the cold-water connection and filtered-water tubing can be routed cleanly around the sink waste and dishwasher plumbing.
Coordinate the Finish
Choose the mixer finish alongside the sink, handles and surrounding kitchen hardware.
Can a 3-Way Mixer Replace an Existing Kitchen Tap?
In many kitchens, yes. A compatible 3-way mixer can replace the existing kitchen mixer while the filtration system is installed beneath the sink.
The installation still needs sufficient cabinet space for the filter and suitable plumbing for the hot, cold and filtered-water connections.
Before Replacing the Existing Mixer, Check:
- Existing tap mounting position.
- Sink or benchtop thickness.
- Tap-hole size and configuration.
- Clearance around splashbacks or windows.
- Spout height and reach.
- Cabinet space for filtration.
- Existing hot and cold isolation valves.
- Sink waste and dishwasher plumbing.
- Access for future cartridge servicing.
JR Installer Verdict: Most of the complexity is underneath the sink. A mixer can look like a simple swap from above while the cabinet below determines how cleanly the filtration can actually be installed.
What Size Under-Sink Filter Do I Need?
Filter size should be based on the required treatment, drinking-water demand, cartridge capacity and available cabinet space rather than the size of the 3-way mixer.
Compact Single System
Useful where cupboard space is limited and one appropriate treatment cartridge meets the goal.
Twin System
Allows two treatment stages where a combined filtration approach is useful.
Reverse Osmosis System
Requires additional equipment and space where membrane treatment is selected.
JR Installer Verdict: The tap does not determine filter size. Match the filtration to the water goal and household drinking-water use.
Filtered Water Flow Through a 3-Way Mixer
Filtered-water flow can differ from normal hot and cold mixer flow because the drinking water passes through filtration media, tubing and a dedicated filtered-water pathway.
The practical flow depends on the cartridge, system design, incoming pressure, tubing and the mixer itself.
Normal Mixer Flow
Designed for everyday sink tasks such as rinsing, filling and washing.
Filtered-Water Flow
Normally lower because water passes through the dedicated filtration system before reaching the outlet.
JR Installer Verdict: A drinking-water filter does not need the same flow as the main kitchen mixer, but it should still be fast enough for convenient glasses, bottles and cooking.
Why Water Pressure Matters
Incoming water pressure affects both normal mixer performance and filtered drinking-water flow.
Every cartridge creates some resistance to flow. The amount depends on the filter media, cartridge design, water pressure, tubing and how loaded the cartridge has become.
JR Installer Verdict: If filtered-water flow becomes significantly slower over time, inspect the cartridge and system rather than assuming the mixer itself has failed.

How Much Does a 3-Way Water Filter Mixer Cost?
Cost varies according to the mixer, finish, filtration system and installation requirements. A basic cartridge filter paired with a value-focused 3-way mixer is a different installation from a premium designer mixer with reverse osmosis.
JR Gas & Water displays current mixers, filtration options and installed pricing in the live range above so customers can compare real combinations rather than relying on a broad generic estimate.
What Changes the Installed Price?
- Mixer brand and model.
- High-loop, high-rise or pull-out design.
- Tap finish.
- Single, twin or specialist filtration.
- Reverse-osmosis filtration where selected.
- Existing mixer removal.
- Existing isolation valves and plumbing.
- Cabinet space and access.
- Sink or benchtop configuration.
- Additional plumbing required.
- Future cartridge replacement costs.
JR Installer Verdict: Compare the complete mixer-and-filter installation. A 3-way tap without the right filtration underneath it does not achieve the water-treatment result you are buying it for.
3-Way Mixer & Water Filter Maintenance
The mixer itself and the filtration system have different maintenance requirements. The tap is a plumbing fixture, while the cartridge beneath the sink is a consumable treatment component.
Filter Cartridge
Replace according to the cartridge capacity, water usage and manufacturer service requirements.
Mixer Operation
Controls and spout operation should remain smooth and free from leaks.
Filtered-Water Flow
A significant reduction can indicate a loaded cartridge or another restriction.
Flexible Connections
Accessible connections can be inspected during servicing for signs of leakage or deterioration.
Under-Sink Tubing
Filtered-water tubing should remain secure and correctly routed inside the cabinet.
Service History
Recording filter changes makes ongoing maintenance much easier.

How to Choose the Right 3-Way Mixer
1. Choose Your Filtration
Determine what you want treated and select the filtration technology first.
2. Choose the Mixer Shape
Compare high-loop, high-rise and pull-out designs around how the sink is used.
3. Choose the Finish
Match the mixer to the sink, handles and other visible kitchen hardware.
4. Check Dimensions
Make sure the spout height, reach and operating controls suit the sink and surrounding cabinetry.
5. Check Under-Sink Space
Allow enough room for the filter and future cartridge changes.
6. Check Compatibility
Confirm the selected mixer and filtration system can operate together as intended.
Common 3-Way Kitchen Mixer Mistakes
Choosing the Tap Before the Filter
The filter determines treatment performance, so decide what you want the water system to achieve first.
Assuming the Mixer Filters Water
A 3-way mixer distributes filtered water but does not perform the filtration by itself.
Ignoring Spout Reach
A mixer can look excellent online but be awkward if its dimensions do not suit the actual sink.
Ignoring Cabinet Space
The mixer may fit perfectly while there is nowhere practical for the filtration system underneath.
Filtering All Cold Water Unnecessarily
Using a dedicated filtered-water pathway helps avoid consuming cartridge capacity for ordinary sink use.
Confusing 3-Way with Boiling Water
A standard 3-way mixer provides hot, cold and filtered water, not instant boiling water.
Choosing by Finish Alone
Tap functionality, spout geometry and filtration compatibility matter as much as colour.
No Service Clearance
The water filter still needs enough room for future cartridge removal and replacement.
What We Look for in a 3-Way Filtered Mixer
Separate Filtered-Water Function
The point of a 3-way mixer is to provide filtered drinking water without turning every normal cold-water use into filtered-water use.
Good Everyday Mixer Design
The tap still needs to work well for washing, rinsing and filling large pots every day.
Practical Filter Compatibility
The mixer should pair cleanly with an appropriate filtration system.
Useful Filtered-Water Flow
Drinking-water flow should remain practical for glasses, bottles and cooking.
Suitable Dimensions
Spout height and reach need to suit the actual sink rather than simply looking good in a product image.
Long-Term Serviceability
Mixer parts and replacement filter cartridges should remain practical to maintain after installation.

3-Way Kitchen Mixer FAQs
What is a 3-way kitchen mixer?
A 3-way kitchen mixer provides normal hot water, normal cold water and dedicated filtered drinking water through one kitchen tap.
How does a 3-way water filter tap work?
The mixer connects to the normal hot and cold supplies while a separate filtered-water connection receives water from the under-sink filtration system. The exact internal arrangement depends on the mixer design.
Does a 3-way mixer include a water filter?
The mixer itself is the tapware. Some packages include or are paired with a filtration system, but the actual treatment comes from the filter installed beneath the sink.
Is a 3-way mixer better than a separate filter tap?
Neither is universally better. A 3-way mixer provides a cleaner single-fixture appearance, while a separate filter tap can allow a good existing kitchen mixer to remain in place.
Can a 3-way mixer replace my existing kitchen tap?
Often yes, provided the mounting position, sink or benchtop and under-sink plumbing are suitable for the selected mixer and filtration system.
Can I install a 3-way mixer with a stone benchtop?
Yes, subject to the existing tap position and installation conditions. A 3-way mixer can be particularly useful where adding a separate filter-tap penetration is not appropriate.
Does filtered water mix with normal hot and cold water?
Compatible 3-way mixers are designed to provide a dedicated filtered-water function separate from ordinary mixer operation. The exact water-path design depends on the individual product.
Does a 3-way mixer provide boiling water?
A standard hot-cold-filtered 3-way mixer does not provide instant boiling water. Boiling, chilled and sparkling systems are a separate category using powered under-bench appliances.
Can a 3-way mixer work with reverse osmosis?
Selected mixer and RO combinations can be compatible, but the complete system should be checked before purchase because RO production, pressure and tap requirements differ from conventional cartridge filtration.
What water filter should I use with a 3-way mixer?
Choose the filter according to the water-treatment goal. Options can include standard under-sink cartridge filtration, twin-stage filtration and compatible reverse-osmosis systems.
Does a 3-way mixer remove chlorine?
The mixer itself does not remove chlorine. Suitable activated-carbon filtration connected to the filtered-water pathway can reduce chlorine where the individual cartridge is designed and rated for that purpose.
Can a 3-way mixer filter PFAS?
The tap does not determine PFAS treatment. A suitable filtration system with verified PFAS reduction performance needs to be connected to the filtered-water pathway.
Can a 3-way mixer reduce fluoride?
Fluoride reduction depends on the filtration system, not the mixer. Suitable reverse-osmosis or specialist filtration can be used where fluoride reduction is the treatment goal.
What is the difference between high-loop and high-rise mixers?
They describe different tap shapes and proportions. The best choice depends on sink size, required clearance, preferred appearance and how the kitchen tap is used.
Can I get a pull-out 3-way mixer?
Yes. JR's current range includes pull-out 3-way mixer options combining normal mixer operation, a flexible pull-out head and a filtered-water function.
Does a 3-way mixer use filters faster?
Filter life depends on the cartridge and filtered-water consumption. One advantage of a dedicated filtered-water function is that normal cold-water sink use does not need to consume drinking-water cartridge capacity.
How often does the filter need replacing?
There is no universal service interval. Cartridge life depends on the filtration system, rated capacity, water consumption, incoming water conditions and manufacturer requirements.
Do 3-way mixer taps need electricity?
A standard 3-way mixer paired with normal cartridge filtration generally does not require electricity simply to provide hot, cold and filtered water. Powered RO or premium appliance systems can have different requirements.
What finishes are available for 3-way mixers?
The current JR range includes options such as chrome, brushed nickel, stainless steel, matte black, gunmetal and brushed gold, depending on the individual mixer.
Do you install Puretec Tripla mixers?
Yes. JR's current 3-way mixer range includes multiple Puretec Tripla models, styles and finishes.
Do you install 3-way water filter mixers in Brisbane and Gold Coast?
Yes. JR Gas & Water supplies and installs 3-way filtered kitchen mixers throughout Greater Brisbane, the Gold Coast and surrounding South East Queensland service areas.
