WATER FILTER MAINTENANCE SERVICE
Water Filter Cartridge Replacement Service
Your water filtration system relies on correctly fitted filter cartridges to maintain the flow and filtration performance it was designed to provide.
As cartridges collect sediment and other material over time, water flow can reduce and filtration performance can change. The Water Filter Cartridge Replacement Service provides professional labour to remove your existing cartridges, install the replacement cartridges you have purchased and check the system before it is returned to service.
This is a maintenance service for an existing installed filtration system. Replacement cartridges must be purchased separately, and additional fittings, housings, valves or other replacement components are not automatically included.
Quick answer:
buy the correct replacement cartridges for your filtration system and Installed Today can replace them professionally. The service includes cartridge removal and installation, housing cleaning, inspection of accessible components and seals, reassembly, leak checking and operational testing before the filtration system is returned to use.
WHY REPLACE FILTERS
Why Do Water Filter Cartridges Need Replacing?
Water filter cartridges are service items. As water passes through them, the filtration media gradually collects sediment or reaches the end of its intended service life.
Leaving cartridges in service beyond the replacement interval recommended for the filtration system can contribute to reduced flow, changed taste or odour, increased pressure drop and reduced filtration performance.
Maintain Water Flow
A heavily loaded cartridge can restrict water flow and increase pressure drop through the filtration system.
```
Maintain Filtration Performance
Replacing cartridges at the appropriate interval helps the filtration system continue operating as intended.
Inspect the System
Cartridge replacement provides an opportunity to check housings, accessible seals and connections for visible wear, leaks or damage.

WE REPLACE WHAT YOU BUY
Purchase the Cartridges & We Handle the Replacement
The service is designed around a simple process: you purchase the correct replacement cartridges for your existing filtration system and the technician completes the cartridge change and standard maintenance work.
The replacement service does not automatically include new valves, fittings, housings, pipes or other replacement components.
If a damaged seal, housing, fitting or other component is found during the service, any replacement part required outside the purchased cartridges may need to be supplied or purchased separately before the repair can be completed.
HOW THE SERVICE WORKS
What Happens During a Cartridge Replacement?
1. Isolate the Water
The filtration system is isolated and pressure is released so the housings can be opened safely.
```
2. Remove Old Cartridges
The existing cartridges are removed from the filter housings.
3. Clean the Housings
Accessible housings are cleaned to remove collected sediment and residue before the new cartridges are fitted.
4. Inspect Seals & Components
Accessible O-rings, seals, housings and connections are visually checked before reassembly.
5. Install New Cartridges
The purchased compatible cartridges are fitted in the correct housing positions.
6. Repressurise & Check
The filtration system is returned to service and checked for leaks, normal flow and correct operation.

SERVICE SUITABILITY
Which Water Filter Systems Can This Service Suit?
The cartridge replacement service is intended for existing operational filtration systems where compatible replacement cartridges have already been purchased.
Under-Sink Filters
Suitable cartridge-based under-sink drinking water systems can be serviced where the housings are safely accessible.
```
Whole-Home Filters
Cartridge-based whole-home filtration systems can be serviced where the housings, isolation valves and work area are readily accessible.
Multi-Stage Systems
Multiple cartridges can be replaced where the correct compatible cartridge set has been purchased for the installed system.
```
CARTRIDGE COMPATIBILITY
Make Sure You Buy the Correct Replacement Cartridges
The replacement cartridges need to match the filtration system already installed at the property.
Cartridges can differ by physical size, filtration media, flow direction, connection style and system-specific requirements. A cartridge that physically fits a housing should not automatically be assumed to be the correct replacement.
Check the existing filter system before ordering cartridges.
Use the filtration system manufacturer's replacement cartridge requirements where available. If you are unsure which cartridges your system uses, identify the system and cartridge model before booking the replacement service.
WHEN TO REPLACE
When Should Water Filter Cartridges Be Replaced?
Replacement intervals vary between filtration systems and should follow the cartridge or system manufacturer's instructions.
Many cartridge systems use service intervals measured in months or litres treated, but actual cartridge life can vary with water quality, household usage and the type of filtration media.
- Manufacturer replacement interval has been reached
- Reduced water flow through the filtration system
- Noticeable change in filtered-water taste or odour
- Visible sediment loading in applicable cartridges
- System service reminder is due
- Rated cartridge capacity has been reached
- Cartridges have been left in service beyond their recommended life
- System has been out of use and the manufacturer recommends cartridge replacement
A general 6–12 month interval is common for some cartridge systems, but the correct replacement schedule is the one specified for the particular filtration system and cartridges installed.
ACCESS REQUIREMENTS
What Access Is Required for the Service?
The filtration system needs to be safely accessible so the technician can isolate the water supply, open the housings, remove the cartridges and complete the maintenance work.
Under-Sink Systems
The cupboard should be cleared sufficiently to provide safe access to the filter housings, isolation valve and connections.
```
Whole-Home Systems
The filtration housings and associated isolation valves should have clear working space around them.
Restricted Locations
Very tight cabinetry, obstructed plumbing or difficult access can increase the service scope and may require additional work.
