Yes. Most apartments and rentals can use a water filter. Filter jugs and manually filled benchtop units make no plumbing changes. Tap-connected models require a compatible outlet, while under-sink systems generally need permission and installation by a licensed plumber.
Which filters are suitable?
| Filter type | What to consider |
|---|---|
| Filter jug | No plumbing connection or permanent change |
| Non-plumbed benchtop filter | Manually filled and usually fully removable |
| Tap-mounted filter | Must suit the tap thread, aerator and mixer design; check the manufacturer’s instructions |
| Under-sink filter using the existing mixer | Connects to the fixed cold-water service and may alter plumbing |
| Under-sink filter with a separate tap | Requires a fixed connection and may require drilling through the sink or benchtop |
For the most renter-friendly option, choose a jug or non-plumbed benchtop water filter. Do not assume a tap-mounted model is compatible or permitted simply because it is removable.
When is approval needed?
Tenants should obtain written approval from their landlord or agent before drilling, replacing fixtures, altering cabinetry or changing fixed plumbing. Check the lease and agree in writing on removal and restoration requirements.
In a strata property, ask the strata manager or owners corporation whether the installation affects common property. Landlord approval does not replace any required strata approval. Approval requirements depend on the work and the property, so confirm uncertain cases with NSW Fair Trading or the strata manager before proceeding.
What should you check?
Before buying, confirm:
- the tap or mixer is compatible with the manufacturer’s fittings
- there is enough cupboard space around waste pipes, drawers and isolation valves
- cartridges can be replaced without straining hoses or moving plumbing
- any approved removable fittings can be reinstated without damage
- the proposed work has all required written approvals.
Only make visual checks. Do not dismantle taps or pipework to test compatibility.
When is a licensed plumber needed?
Use a licensed plumber when the filter connects to fixed water services or requires pipe or fixture alterations. Do not drill near concealed services, modify shared plumbing or attempt pressurised pipe connections yourself; mistakes can cause leaks and damage your apartment or neighbouring property.
Plumbed water filter installations in Australia must comply with AS/NZS 3500.1 (the national water supply standard that requires backflow protection and pressure control to prevent filter carbon from backsiphoning into the mains and protect filter housings from pressure surges). If a fixed connection or dedicated tapware change is required, contact our Sydney water-filter installation team to assess compatibility and complete the installation safely. Fixed Today has helped Sydney apartment dwellers and homeowners since 2011 with compliant plumbing solutions, upfront fixed pricing, and clear task breakdowns. Informing our team whether your unit has individual stop taps under the sink, stone benchtops, or strict strata water-isolation guidelines helps our licensed technicians arrive with the correct pressure-limiting valves, adaptors, and diamond hole saws.
