UNDER-SINK WATER FILTER INSTALLATION
Under-Sink Water Filter Installation Package
The Under-Sink Water Filter Installation Package is designed for customers who have purchased an under-sink filtration system and want it professionally connected to the existing kitchen or laundry plumbing.
Unlike a basic labour-only installation, this package includes the standard fittings, isolation valves and up to 2 metres of applicable pipework alterations required to integrate the filtration system into a suitable existing cold-water supply.
The package is intended for accessible under-sink installations where the filtration system fits within the available cupboard space and the existing plumbing is in suitable condition.
Quick answer:
the package covers professional installation of your purchased under-sink filtration system, standard connection fittings, inlet and outlet isolation valves where required and up to 2 metres of applicable pipework alterations. Major plumbing rerouting, system relocation, electrical work and repairs to damaged existing plumbing are outside the standard installation scope.

HOW IT WORKS
How Is an Under-Sink Water Filter Installed?
1. Cold Water Is Isolated
The suitable cold-water supply beneath the sink is isolated so the filtration connections can be installed.
```

The filtration system is mounted or positioned within an accessible under-sink location suitable for future servicing.
3. Plumbing Is Connected
Applicable fittings, isolation valves and pipework alterations are completed to connect the filter inlet and outlet.
4. Tap Is Connected
The filtered-water outlet is connected to the compatible dedicated filter tap or 3-way mixer being used with the system.
5. System Is Repressurised
The water supply is restored and accessible connections are checked for leaks.
6. Filter Is Prepared for Use
The system is flushed or prepared in accordance with the requirements of the filtration system and cartridges supplied.
```
INSTALLATION LOCATION
Where Can the Filter System Be Installed?
The standard package is designed for installation under a kitchen or laundry sink where a suitable cold-water connection and sufficient working space are available.
- Suitable under-sink cupboard or cabinet
- Existing cold-water supply nearby
- Clear access to the plumbing
- Adequate room for the filtration system
- Enough clearance for cartridge changes
- Suitable position for isolation valves
- Accessible filtered-water outlet connection
- System can be serviced without major cabinet removal
SPACE REQUIREMENTS
Make Sure There Is Enough Room Under the Sink
The filtration system needs to fit inside the available cabinet while remaining accessible for future cartridge replacement and maintenance.
Allow enough space around filter housings so they can be opened or removed during servicing. The installation should also avoid interfering with sink bowls, waste pipes, dishwasher hoses and other existing services.
Check the cupboard before ordering.
Measure the filtration system and compare it with the available under-sink space, including the clearance needed to remove filter housings or cartridges during future maintenance.
WATER CONNECTION
What Water Supply Does an Under-Sink Filter Use?
The standard under-sink filtration installation connects to the cold-water supply.
The exact connection arrangement depends on the filtration system, existing plumbing and whether the outlet feeds a separate drinking-water tap or a compatible 3-way kitchen mixer.
The existing supply needs to be in suitable condition and provide an appropriate operating pressure for the filtration system being installed.
FILTER TAP OR 3-WAY MIXER
How Does the Filtered Water Reach the Sink?
Dedicated Filter Tap
A separate drinking-water tap can be installed where the sink or benchtop has a suitable mounting position and the required tap is included in the order.
```
3-Way Kitchen Mixer
A compatible 3-way mixer can combine normal hot and cold water with a separate filtered-water pathway through one tap body.
Existing Compatible Tap
An existing filtration tap may be reused where it is compatible, in suitable condition and appropriate for the new filtration system.
```
A new filter tap or 3-way mixer is not automatically included unless it forms part of the product or installation package purchased.
ISOLATION VALVES
Why Are Isolation Valves Included?
Isolation valves allow the filtration system to be shut off for cartridge changes and maintenance without unnecessary disruption to other plumbing.
Where required for the approved installation, applicable inlet and outlet isolation valves are included as part of this package.
The final arrangement depends on the filtration system and the existing plumbing configuration beneath the sink.
EXISTING PLUMBING
What Condition Does the Existing Plumbing Need to Be In?
The standard package assumes the existing under-sink plumbing is serviceable and suitable for connection to the new filtration system.
Corroded pipework, active leaks, damaged isolation valves, unsuitable flexible hoses or other existing plumbing defects may need to be repaired before or during installation.
Existing plumbing repairs are separate.
The included pipework allowance is for integrating the new filtration system, not for replacing large sections of deteriorated or non-serviceable existing plumbing.
NOT INCLUDED
What Is Not Included in the Standard Installation?
- Relocation away from the nominated under-sink position
- Major plumbing rerouting
- Pipework beyond the included standard allowance
- Repair of damaged existing plumbing
- Replacement of unrelated valves or hoses
- Cabinet reconstruction or major carpentry
- Stone benchtop alterations unless separately approved
- Electrical modifications
- Drainage modifications unrelated to the filtration system
- Additional filtration stages not included in the purchased system
- Filter tap or 3-way mixer unless purchased
- Work outside the approved under-sink installation scope
ACCESS REQUIREMENTS
What Access Is Required for Installation?
The under-sink area needs to provide enough clear working space for the installer to reach the cold-water supply, position the filtration system and complete the connections.
Clear the Cupboard
Remove stored items from beneath the sink before installation so the work area and plumbing are accessible.
```
Visible Plumbing
Existing pipework and isolation points should be accessible without significant cabinet removal or demolition.
Service Access
The final filtration system needs enough clearance for future cartridge replacement and routine maintenance.
```
Restricted cabinetry, hidden plumbing or significant obstructions can increase the work required and may fall outside the standard installation scope.

Can You Relocate the Plumbing?
Minor pipework alterations within the included allowance are covered, but major rerouting or relocation is outside the standard package unless separately approved.
Does the Cupboard Need to Be Empty?
The area should be cleared sufficiently to provide safe access to the plumbing and enough working space to position and connect the filtration system.
Does the System Need Space for Future Filter Changes?
Yes. Adequate clearance should be maintained around filter housings and cartridges so future maintenance can be completed without removing major cabinetry or plumbing.
